Training Nonhuman Primates to Cooperate during Blood Collection: A Review

Viktor Reinhardt
Animal Welfare Institute, Washington, DC

Traditionally, laboratory nonhuman primates are regarded as dangerous and often vicious animals. Therefore, forced restraint is often recommended for handling them. During blood collection, one of the most common laboratory procedures, primates are restrained either mechanically in a cage or manually on a table. Despite such precautions, however, restrained animals occasionally bite and scratch handling personnel, posing a serious risk of zoonoses transmission (Valerio et al., 1969; Zakaria et al., 1996). Such accidents are not surprising, because the subdued animal is afraid and therefore tries to defend itself.

The excitation associated with involuntary blood collection is reflected in numerous physiological deviations which preclude the collection of scientifically reliable data (Reinhardt et al., 1995). This problem is usually dealt with by not mentioning how the experimental subjects were handled and by using more of them to improve statistical significance (Brockway et al., 1993).

The scientific and ethical inadequacy of forced restraint is implicitly acknowledged by the International Primatological Society, which underscores in its International Guidelines for the Acquisition, Care and Breeding of Nonhuman Primates (1989) that restraint "should be used only when less stressful alternatives are not feasible." Training animals to cooperate during procedures offers such an alternative, which: * refines scientific methodology by controlling extraneous stress-related variables; * decreases the risk of injury by no longer giving the animal a reason to show aggressive defense reactions; * reduces the amount of time and the number of people required to perform a procedure by eliminating the need to subdue the resisting subject; * challenges the intelligence of animals and attending personnel alike; and * improves the work environment of animal care personnel by creating a human-animal relationship which is based on trust rather than fear. The International Primatological Society explicitly states that "primates of many species can be trained for sample procedures, such as presenting a limb for a blood collection," and advocates such training "whenever possible" (IPS, 1989).

Casual Observations

Numerous authors allude to the possibility of training nonhuman primates to cooperate during blood collection.
* Rhesus macaques (Macaca mulatta). Elvidge et al. (1976): females "have been trained to jump from their cage into an aluminum box and offer a hind leg for sampling." Bernstein et al. (1977) and Eaton et al. (1994): males and females were transferred to small cages, where they had been trained to present a leg for blood collection. Rosenblum & Coulston (1981): both sexes "were trained to present an arm through a small cage opening" to facilitate blood sampling. Herndon et al. (1984): males "often extended a leg from the cage without struggling for sample collection." Billiard et al. (1985): blood samples were obtained from both sexes "by the volunteer method in which an animal learned to present a leg out of a transfer cage." Scallet et al. (1989): males "had been readily conditioned to voluntarily present an arm for sampling, which enabled them to avoid restraint."
* Longtailed macaques (M. fascicularis). Hein et al. (1989): females "were trained to present their arms through the bars of the cage" for venipuncture.
* Chimpanzees (Pan troglodytes). Byrd (1977): one animal was trained "to tolerate a fingerprick to obtain blood for cell counts." McGinnis & Kraemer (1979): blood samples "can be collected easily from chimpanzees that have been trained to cooperate in venipuncture." Fulk (1992): "a few institutions have trained chimpanzees to extend an appendage through the containment barrier in order to collect medical specimens." Laule et al. (1992): male chimpanzees were "trained to allow voluntary blood sampling."
* Various species. Wall et al. (1985): female vervet monkeys (Cercopithecus aethiops) were "trained to present a limb for unstressed sampling." Suleman et al. (1988): vervet monkeys, Sykes monkeys (C. mitis), and baboons (Papio anubis) "were trained to present an arm or leg for blood collection." Chambers et al. (1992): "Non-human primates, particularly the larger macaques, vervets, baboons and apes, are readily trained to cooperate in procedures such as presenting an arm for blood collection."

Detailed Reports

Only a few authors provide the detailed protocols that were used to teach nonhuman primates to cooperate during blood collection.
* Walker et al. (1982) and Dettmer et al. (1996) trained rhesus macaques and capuchin monkeys (Cebus apella), respectively, to extend their legs for venipuncture in a squeeze cage by habituation. The animals were restrained to the front of the cage, allowing the experimenter to reach inside and grasp a leg. They were then reinforced with food for sitting quietly and allowing a blood-draw. Rhesus macaques "quickly learn to extend their legs and after only a few trials volunteer their legs readily" (Walker et al., 1982); "None of the capuchin monkeys learned to present a leg, but four (of eight) showed little resistance" (Dettmer et al., 1996).

* Phillippi-Falkenstein & Clarke (1992) conditioned rhesus macaques to accept blood collection. The animals were first acclimatized to being confined in the front portion of the sampling cage. Once the animals were "habituated to sitting in the front of the cage, a technician reached in for the monkey's foot and pulled it through the hole in the sample cage. If an animal offered no resistance or extended its leg, no restraint was applied. The leg was held and gently pinched to acclimate the animal to being touched. After three minutes, the animal's leg was released, gently pushed into the cage, and a reward given." After 17 days of training, all animals remained calm when blood samples were collected and three of the five females "extended their legs voluntarily."

*Vertein & Reinhardt (1989) trained adult pair-housed rhesus females for blood collection in their home cages rather than in a sampling cage. The animals were first acclimatized to being confined once a day in the front portion of their cages. In subsequent sessions, each subject's leg was touched several times. Next, the trainer gently pulled the leg out of the cage, holding it for about 20 seconds before releasing the leg and offering a food reward. During the 24th and last session, blood was collected. None of the eight monkeys showed signs of resistance, but only three of them willingly presented a leg for venipunture.

* Reinhardt (1991) modified this training protocol in order to improve the overall success rate. Plexiglass panels were fitted over the open cage doors during each training session; they had an aperture large enough for a monkey's leg to fit through, but small enough to prevent the monkey from escaping. Initially, the back wall was pulled so close to the front of the cage that the males could not turn around freely. This allowed the trainer right from the beginning to reach through the aperture of the panel, groom a leg of the subject, carefully lift the leg, gently yet firmly pull the leg out of the cage, and puncture the saphenous vein. Once the animal stopped resisting, the back wall was pulled less close, leaving the trainee leeway to refuse being touched and room to turn freely around. Sessions were never terminated before a leg was brought out for long enough to draw a blood sample. When this was achieved the back wall was pushed into its normal position and the animal rewarded with favored food. On average, 24 minutes distributed over six training sessions were required to overcome the males' initial resistance; an additional 14 minutes distributed over seven sessions were then invested until each of the 15 males voluntarily presented a leg behind, in, or through the aperture of the panel and showed no resistance during blood collection. Pair-housed males and single-housed males did not differ significantly in their training performance. Once the training goal was achieved, the males reliably cooperated not only with the trainer but also with the attending care personnel.

* This training protocol was applied with equal success in six adult female stumptailed macaques (M. arctoides), and with less success in six juvenile female rhesus macaques (Reinhardt & Cowley, 1992; Reinhardt, 1992).

Figure 1a: Adult male rhesus macaques can be trained within a cumulative total of less than one hour to actively present a leg in their homecage ...

Figure 1b: .... and display no resistance during blood collection.

* Priest (1990, 1991) shaped the behavior of Loon, an adult male drill (Mandrillus leucophaeus), to cooperate during blood collection in his home cage. First, the animal was conditioned to reach on command into a stainless steel tube, which was attached to the front of the cage, grasp with his extended arm a rod positioned at the end of the tube, and remain in this position until a clicker sounded, immediately followed by a food reward. Through a hole cut in the tube, the trainer gradually desensitized Loon to being touched at the venipuncture site while Loon was still holding onto the rod. Finally, veni-puncture was accomplished and blood withdrawn.

* Laule et al. (1996) trained Allie, an infant female chimpanzee, for venipuncture. She was taught to sit on a table and allow her arm to be manipulated and held by the trainer. Next, she was desensitized to having her arm touched by, first, the trainer's finger, then a cotton swab, and then a syringe without a needle, with a blunt needle, and finally with a sharp needle. The first blood draw occurred during the 18th training session, with a total of 275 minutes invested prior to that. Allie showed no resistance but sat quietly and eagerly accepted rewards.


These reports provide sufficient evidence that nonhuman primates need not be forcibly restrained and distressed during blood collection. Since primates are intelligent, it is not surprising that even adult male rhesus macaques, supposedly very aggressive and hence intractable, learn within less than one hour to voluntarily present a limb and accept blood collection in their home cages (Figures 1a-b). There is no reason why the training techniques developed for rhesus macaques could not be applied with the same effectiveness to macaques in general and to other medium-sized primates such as capuchin and vervet monkeys and female baboons. The technique developed for Loon, the male drill, is probably adequate for other more powerful primates such as male baboons and chimpanzees.

So far only a few laboratory primates have been taught to cooperate during blood collection. This suggests that the myth of the unpredictably fractious monkey still prevails. The publications cited here question this myth and encourage more attempts to replace conventional blood sampling procedures with training techniques that draw on the animals' inherent learning capabilities and willingness to cooperate, thereby improving animal welfare, personnel safety, and research methodology.

Letter To The Editor

In the last issue of Laboratory Primate Newsletter, a notice on changes to nomenclature is included. Your conservative approach of the past was probably prudent, but your recent adoption of nomenclatural changes is also right on target. Wilson and Reeder (Mammal Species of the World: A Taxonomic and Geographic Reference, 2nd Ed.) are now the acccepted sources for mammalian taxonomy, and this level of acceptance is much higher than indicated. CITES has adopted all aspects of its recommended changes and ISIS, the computer data base used by zoos, is preparing to incorporate these changes as well. When money becomes available, names of species covered by the Endangered Species Act are also likely to be changed as appropriate. - Alan Shoemaker, Collection Manager, Riverbanks Zoo, Columbia, SC 29202

Nonhuman Primates in Viral Hepatitis Research

Marisa St. Claire


Over the past 30 years, seven hepatitis viruses have been identified and named A, B, C, D, E, G, and GB. These viruses are approaching HIV, the virus that causes AIDS, in their collective contribution to human illness and death, and are far easier to contract than HIV. More than 500,000 Americans become infected with some form of viral hepatitis each year, and about 16,000 die annually from the complications. Probably the best described has been Hepatitis B virus (HBV), a DNA virus that replicates through an RNA intermediate. HBV is transmitted via parenteral drug use, sexual contact, blood products, and occupational exposure. HBV infection is frequently seen among HIV-positive individuals; up to 90% of HIV positive persons are also seropositive for HBV. Hepatitis C virus (HCV), a RNA virus discovered in 1988, is like HBV in that it is primarily blood-borne, and both HCV and HBV cause acute as well as chronic hepatitis and can lead to cirrhosis and hepatocellular carcinoma in humans. Epidemiology data from case-control and cohort studies and from laboratory investigations indicate that up to 80% of cases of hepatocellular carcinoma are attributable to persistent infection with HBV. HBV is thus second only to tobacco among known human carcinogens. HCV accounts for 150,000 cases per year with 10,000 deaths annually in the U.S., and up to 80% of HIV-positive individuals are also seropositive for HCV.

Hepatitis A virus (HAV) and hepatitis E virus (HEV) are transmitted enterically and induce acute hepatitis but rarely result in chronic hepatitis. HAV has received media attention due to food-borne outbreaks. A recent example is the HAV-contaminated strawberries from Central America and Mexico, which were purchased for schoolchildren in the southwestern United States in early spring of 1997. Approximately 72,000 cases of HAV were reported in the U.S. between 1992-1994, but the true incidence is probably in the millions, since many cases are clinically inapparent. Major epidemics of HAV are especially prevalent in developing countries due to fecal contamination of food and water. HEV resembles HAV in the manner of spread and is prevalent in Asia, Mexico, and Africa. HEV typically causes an acute disease with low mortality, except in pregnant women, where there is a high risk of death - up to a 30% fatality rate among women infected with HEV during pregnancy in developing nations.

Hepatitis D virus (HDV), or delta virus, is exceptional in that it is dependent on co-infection with HBV for causing disease, and can modify the illness associated with that virus. Recently, novel blood-borne viruses were discovered and named hepatitis GB virus, (HGBV) a Flavivirus-like agent, and hepatitis G virus (HGV). Both are positive, single-stranded RNA viruses and resemble HCV. The HGBV are further subdivided into GB-A, GB-B, and GB-C, although HGB-C is actually HGV. HGB-A viruses appear to be indigenous to New World Primates. HGBV-A-like viruses have been detected in Saguinus mystax, S. labiatus, S. oedipus, S. nigricollis, Callathrix jacchus, and Aotus trivirgatus. These animals appear to be chronically infected, and no apparent disease has been seen with infection with HGB-A. Although HGV was initially isolated from a human, HGBV-A and -B are not currently thought to be infective to humans.

Animal Models of Viral Hepatitis

Hepatitis A Virus: Macaques (Macaca spp.), owl monkeys (Aotus spp.), and tamarins are susceptible to infection with HAV, although they rarely, if ever, exhibit clinical signs of infection other than liver enzyme elevations and seroconversion. Most commonly, the rhesus macaque (Macaca mulatta) and mustached tamarins (Saguinus mystax) are used in HAV research. Although some types of HAV may be grown in vitro, wild-type HAV is isolated and biologically amplified in cell culture only with great difficulty, and some strains of HAV are completely refractory to isolation in cell culture. Thus, many strains of HAV cannot be studied without a nonhuman primate host.

Hepatitis B and Hepatitis C Viruses: Chimpanzees (Pan troglodytes) are the only species, other than humans, that are susceptible to infection with HBV and HCV. Although chimpanzees rarely show any clinical signs, liver enzyme elevations and antibody formation occurs, and some viruses may be re-isolated from the liver of infected animals.

Hepatitis E Virus: Macaques and Aotus can be infected with HEV. Nonhuman primates are vital for the study of HEV, since it has not been replicated in cell culture. Nonhuman primates serve to biologically amplify HEV, thus allowing study of this virus.

Hepatitis G and GB Virus: Tamarins can be infected with HGV (a.k.a. HGB-C) or HGB-B and develop hepatitis. Many New World species appear to be chronically infected with HGB-A and suffer no ill effects.

Other Hepatitis Viruses: Of all the species of nonhuman primates, only chimpanzees can be infected with all known human hepatitis viruses. Therefore, novel hepatitis viruses may be inoculated into chimpanzees (who show no adverse effects from infection), which serve as a biological amplification system, allowing study of these viruses.

Nonhuman primate models have been exceedingly important in hepatitis virus research. Isolation and identification of many exotic viruses has been possible only through the use of nonhuman primates. Development of vaccines for both hepatitis A and B was done in nonhuman primates, and these vaccines have done much to reduce morbidity and mortality in susceptible human populations. In 1980, Taiwan started a program of vaccinating all infants, which resulted in a ten-fold reduction in HBV carrier state and a five-fold reduction in the incidence of hepatocellular carcinoma in Taiwanese children.

Since the highest incidence of hepatocellular carcinoma occurs in the sixth decade of life in humans, it will be many years before we realize the full extent of reduction of mortality due to vaccination. Since 1990, the World Health Organization has recommended a policy of universal vaccination of all children for HBV. Eighty-five countries throughout the world are currently participating, including the United States.

While HAV does not appear to cause chronic infections or increase the risk of development of cancer, as does HBV, it causes tremendous morbidity and some mortality in immunocompromised persons. The recent introduction of a vaccine for HAV (Havrix™) appears to be contributing to its decrease in populations which are most at risk (as well as most likely to be offered vaccination, i.e. health care workers, persons traveling to developing nations, etc.).

Recommendations for Vaccination: Personnel working with nonhuman primates or human cell culture/body fluids should consider vaccination for both HAV and HBV. In addition, some facilities have chosen to vaccinate their nonhuman primates for HAV and HBV if these animals will be part of a study in which liver enzymes, or other clinical parameters that may be affected by infection, are to be monitored. Although the nonhuman primates that are susceptible to human hepatitis viruses do not appear to experience any adverse effects following infection, study directors may wish to have their animals vaccinated so that they may rule out HAV or HBV as a potential cause in the event of a rise in liver enzymes. When performing viral hepatitis research, it is important to screen all incoming nonhuman primates for seroconversion to the various hepatitis viruses prior to putting them on study. Given the prevalence of hepatitis viruses among the general human population and the ease of spread, particularly of HAV and HEV, it is not uncommon to find primates that have already been exposed via their human caretakers.

Elderhostel: An Interesting Way to Increase Public Exposure to Nonhuman Primates in Laboratory Settings

Steven J. Schapiro, Michale E. Keeling, and Marilyn J. Hill
The University of Texas M. D. Anderson Cancer Center,

What you're about to read will not be "scientific", but will supply you with some information that might be useful to you and your facility. We run Elderhostel programs at the Department of Veterinary Sciences of the University of Texas M. D. Anderson Cancer Center in Bastrop, Texas. We'll tell you a little about Elderhostel, what we do with Elderhostel, why we do it, and how it has turned out so far. We'll close with a letter/story that a couple of our Elderhostelers wrote shortly after attending one of our programs. In brief, Elderhostelers, in general, are a group of people that (1) can appreciate the importance of primate models to biomedical research and the importance of conserving endangered primates; (2) are actively seeking knowledge about biomedical research techniques and progress; and (3) are absolutely thrilled when you tell them and show them how you are working with nonhuman primates in a research environment.

Elderhostel is an international organization devoted to providing low-cost, high-quality continuing education programs to adults 55 years of age and over. Thousands of different programs, on virtually every topic you could think of, are offered every year throughout the world. About 300,000 adults enroll in programs each year. A typical Elderhostel program lasts 6 nights (5 days) and includes three separate 7.5 hour courses, but there are as many exceptions to this rule as there are exemplars. Intensive programs, service programs, intergenerational programs, and longer programs are all included in the quarterly catalog. The key to all the programs are the Elderhostelers: people who have chosen to participate in your particular program, and are thus highly motivated to learn about your topics.

At the Department of Veterinary Sciences, we were searching for a low-risk way to publicize the high-quality research we were doing. We know how well we care for our nonhuman primates and other animals, and how this improves the quality of studies that are performed using these well-defined animal models. But it was becoming increasingly obvious that the average person in the public did not know this. We decided that people 55 and older - people who had seen health problems that existed prior to the recent rapid advancements of biomedical research, people who had lost loved ones to afflictions that we are now making progress toward conquering, people who are well-educated and respected in their communities - would be an ideal pilot target audience for us to open our facility to and show all that we do. While we recognize (as do most of the animal rights groups) that school-age individuals are probably the most important subset of the population to "go after" for long-term impact, we wanted to make our initial foray into proactive community education with an audience that we considered likely to be sympathetic to our work and goals.

We offer our Elderhostel program twice a year, in mid-spring and in early fall - the weather is a major influence on our schedule of offerings in Central Texas. Each program consists of three courses and a variety of extracurricular and social activities. The three courses we typically offer are (1) Primate Behavior, (2) Veterinary Medicine and Human Medicine, and (3) The Immune System. All courses are taught by M. D. Anderson faculty and are fairly challenging and rigorous. Courses include lectures, demonstrations, hands-on activities, and numerous readings. Primate-related activities include behavioral observation of chimpanzees and rhesus monkeys, demonstrations of enrichment and positive reinforcement training, and observation of chimpanzees and rhesus monkeys receiving their annual physical exams.

About 88 Elderhostelers have now participated in our programs; both hostelers and our staff have been quite pleased with how the programs have turned out. We still make minor adjustments from one offering to the next, but in general, we have a very workable program in place. We routinely challenge participants at "graduation" to become active and vocal advocates of animal research in general, and primate research in particular. This past April, we were challenged by the participants to do a better job at getting our message to the public. They were so enthusiastic about our program that they wanted us to help them organize a "Bastrop Elderhostel Alumni Network" to really make a difference. We are in the process of doing so now.

We will close with a letter/story written by Mary J. and Phil Zenchoff, two participants at our most recent (April, 1997) Elderhostel program. Obviously, every participant does not send us a similar piece, but the Zenchoffs' story should illustrate (1) what type of impact this kind of educational program could have on the people who come to learn; and (2) what type of community outreach benefits could be gained by your primate research facility from participating in such a program.

We would be happy to talk about our experiences in developing an Elderhostel program and the nuts and bolts of running such a program. (You won't make any money, but if it's done right, you probably won't lose any money, either.) Just contact us at the address above.

Welcome to the Planet of the Apes!

"What's your best Elderhostel?" we are often asked, having racked up 37 of these programs during the past 10 years. Until our week in Science Park at the Department of Veterinary Sciences in Bastrop, Texas this April, we always burbled and said, "They're all great - how can we choose?" Now, with apologies to all the other great ones we've experienced, we answer, "The Planet of the Apes beats them all!"

"What!! Science - chimps - labs! But you're not scientific, Mary" and our friends' noses would wrinkle as I described our plans. Ah yes, but my woman's intuition told me, from the first reading of the descriptive blurb in the Elderhostel catalog, that this week would be wonderful beyond belief. My scientific husband, on the other hand, feared that the technical courses would be so watered down that he would lose interest. By the end of the first class, he was "champing at the bit" for a longer program, and I, of course, was ecstatic, both for myself and for him. Now why was this program so different from all our other trips?

Well, first of all, the science focus was far deeper than any program we had ever experienced before. Our friends' fears that it would be "beyond" anyone without a background in immunology, cancer research, microbiology, primate behavior, and so on, proved to be unfounded. This program was set up as "one size fits all." If you could barely tell an atom from an elephant, you still learned and felt comfortable in the classes.

On the other hand, if you had a fairly solid background in the areas mentioned above, you leaned back happily and soaked in more data. The veterinarians and scientists used slides, hand-outs, and clear graphic explanations to present their points. In addition, we had a fantastic loose-leaf binder packed full of relevant articles that we could peruse at our leisure.

After our classroom lecture each day, we marched off to the lab and saw many of the processes just described in class, such as the cloning of cells, implemented before our wondering eyes. There is a feeling of awe that sweeps over you when you listen to a scientist who has made breakthroughs in creating a vaccine against AIDS, explaining his findings in his inimitably enthusiastic way. Somehow there is a profundity to the experience that remains with you forever.

Then there were the early morning (optional) walks with one of the veterinarians through the wild-flower-dotted fields of Science Park. As we walked, she explained the work being done on bone-replacement after the removal of tumors. At Science Park, sheep are used for this research. We watched in amazement as the research sheep gamboled around their pasture on their sturdy, new-growth legs, with nary a baa-d step, and we rejoiced at the thought of humans, who can someday soon have bone tumors removed, and walk unaided thereafter. Besides, we got into breakfast first if we went on the early walk! Speaking of breakfast, the food was fabulous. The staff prepared both breakfast and lunch, and Southern hospitality was the keyword all week. Dinners were in a class by themselves and will be described later.

And ah! The chimps! We watched with our surgical masks carefully positioned (so WE wouldn't infect the chimp) as he had his yearly physical. There he was, outstretched on the examining table (under light anesthesia, of course) while the veterinarian took a sonogram, measured his body-fat, and yes! checked his prostate. We had a blow-by-blow explanation as the vet performed the procedures - and no, the anesthesia didn't wear off while we were there! I think I heard the chimp mutter, "Next time, Doctor, it's MY turn," but maybe that was my imagination.

Another day, after a fascinating lecture, we trooped off to the chimp area and practiced our observational skills in teams, monitoring the actions of different chimps as they frolicked after their morning meals. Just as a comfort for those who think of smelly monkey houses when we mention "chimps," all our observations were done outdoors, on the roof of the chimp area, while our evolutionary forebears meandered around their playground, probably observing us as well.

Evenings were not for rest! We ate wonderfully and heartily at a different place each evening, toured beautiful historic homes in Bastrop where the owners themselves showed us around, and kicked up our heels in a country Western dance hall, where the Elderhostel staff made sure that no one was left to flounder. Even the Science Park Director came to share the fun and Texas-two-stepped like a pro. Best of all, the staff took multiple photos of all our activities - and on our last day, we could purchase copies of whichever shots we wanted. My only complaint was that there were no picture postcards of Bastrop available in the local stores. Hey, I had my first sentence all set - "Greetings from the Planet of the Apes!"

Re-reading this letter, I only have one qualm - it just doesn't capture both the profundity and the fun of the Bastrop week. The only way to do that is - try the Science Park Elderhostel yourself! - Mary J. & Phil Zenchoff

AWI Offers Enrichment Advice

The Animal Welfare Institute (AWI) has long been interested in improvements in the housing and handling of nonhuman primates used in laboratories. Refinement techniques, which have been tested and implemented at the macaque colony of the Wisconsin RPRC, provide inexpensive but safe stimulation for expression of social behavior and a variety of other species-typical activities. These include training techniques to ensure the animals' cooperation during routine handling procedures, thus minimizing distress reactions.

Developed and implemented by ethologist and former WRPRC veterinarian Viktor Reinhardt, the innovations reflect the spirit of the Animal Welfare Act. AWI encourages other institutions to make use of Dr. Reinhardt's expertise and incorporate some of his ideas into their own plans. A 60-slide series entitled "Environmental Enhancement for Caged Rhesus Macaques" and a written summary are available on loan from AWI, P.O. Box 3650, Washington D.C. 20007 [fax: 202-338 9478; e-mail:]. This series, including summary text and pictures, are available on the Primate Enrichment Forum website at its new address, <>, on the Wisconsin Primate Center server on which the Center has generously donated space.

Dr. Reinhardt will visit interested institutions to offer advice on improving primate housing and handling. AWI will cover consultant fees and lodging expenses. Travel expenses must be covered by the institution. If you are interested in having Dr. Reinhardt visit your institution as a consultant, please contact him at 4605 Crescent Road, Madison, WI 53711 [608-274-9056; e-mail:].

Geographic Information Systems and Conservation

Cedric Campbell Muir is studying population genetics of the orangutan. He has enlisted the help of some computer people to help create some 3-D maps of the Borneo area using USGS bathometry data (geo-topology matrix). They have created videos which simulate the geographic effect of glacially induced sea level and other changes which allow a "fly-by" perspective of the landscape. He has found these "very examine possible migratory pathways which have historically been available (e.g., an extensive `land bridge' which joined the islands of Borneo, Java, Sumatra, and the S. Asian mainland)." You can see some demo videos on his web page: To view the video, you will need to have a video plug-in (right click on a PC) or be accessing the web through Windows 95 (or newer). An article with all the technical details of how the videos were created has been submitted to an electronic journal, assemblage, and is currently in review. For more information, you may contact Dr. Muir at the Institute of Molecular Biology and Biochemistry, Simon Fraser University, Burnaby, B.C., Canada, V5A 1S6 [e-mail:]. - Posted to Primate-Talk

CSU Library Needs Books and Journals

The campus of Colorado State University was damaged in a flash flood on 28 July. CSU's Library was especially hard hit. The Library is nearing the end of a major expansion, and a large part of its holdings was housed in the basement in anticipation of completion of the expansion later this year. The basement suffered extensive damage, and the Library lost all of its bound journals, some 18,000 subscriptions, plus a large number of books. An effort is underway to rebuild the collection, but it will be years before this task is completed.

Kathy Packard, of CSU's Department of Biology, has written asking for help. If anyone nearing retirement is interested in donating back issues of journals or scholarly books to a worthy cause, please consider making the donation to CSU's Library. [Editor's note: We have offered a complete back set of the LPN.]

If you have resources to share, please contact Joel Rutstein, Library, Colorado State Univ., Fort Collins, CO 80523 [e-mail:], who will be coordinating donations. He asks for your patience: Library staff are stretched thin as they try to cope with the flood as well as day-to-day running of the Library.

Environmental Enrichment - Letter From A Zookeeper

Christine Mallar
Zoo Atlanta

Our awareness as animal care professionals has certainly changed in the past few years about the importance of enrichment for captive animals - it's not just important, it's as necessary as food and water. If an animal in a research setting is stressed, it may very well affect his physical well-being, immune system, etc. which may in turn affect the data people are seeking. In a zoo setting, mentally and physically healthy animals exhibit the most natural behaviors for the public and are the ones producing healthy offspring. However, there is a time lag between the evolution of this consciousness and the policies of the institutions involved. This is most clearly seen in the meager allotment of funds to purchase enrichment items. Another area of concern (a pet peeve of mine) is the statement "the animals really liked it, but they made such a mess with it that the caretakers wouldn't give it anymore". I have read this several times during a discussion of enrichment "failures" on the enrichment e-mail discussion group on line and have been wanting to discuss it ever since. As a zookeeper, often a cleaner of hideous messes, I feel I can speak to this issue from both perspectives: benefit to the animals and cost to the caretakers.

When I first became a keeper seven years ago, enrichment was considered a luxury - if you had the time maybe you'd do it, but if you're short staffed, it's the thing you'd skip. However, a few of us very quickly learned its value in preventing behavioral problems that create far more headache and heartache in the long run. When we attempted to implement it regularly, we were sometimes ridiculed by administrators and other keepers, and accused of frittering away our time "playing" with the animals. When we began a positive reinforcement training program, we had to sneak sessions in during our lunch hours. Then, as we started seeing results - our animals were accepting injections voluntarily, easily shifting into squeeze cages, and letting us treat topical wounds - most of the others began to accept the value of such programs and became our strong supporters. Since then, we have made simple enrichment part of the everyday routine: we have a blank calendar with each square filled in, so the keeper just looks at it each day and knows, for example, it's cardboard box day, gives out boxes, and initials the calendar. Cleaning up those box fragments becomes part of cleaning that cage. Just as feces are a fact of life in a monkey cage, so now is some paper or a pile of hay.

The lag we still see is in staffing - caretakers should not be forced to omit enrichment because they cannot complete their tasks otherwise. In the same way that a budget must include buying enrichment items, it is imperative that there be enough people to handle the new tasks. Likewise, enrichment should be part of a keeper's routine, part of the job description, and part of the understood duties for the day. A keeper who doesn't medicate an animal because it's too much trouble to grind up a pill would obviously be held accountable. This has to happen with enrichment as well. If someone can't or won't do it, there are other people out there who would gladly fill that position and pick up that ball (or should I say - give that ball to a monkey). - From a posting to Primate Enrichment Forum, 25 July 1997

Travelers' Health Notes: Pyronaridine: A New Antimalarial Agent

The WHO Special Programme for Research and Training in Tropical Diseases (TDR) is developing a new antimalarial agent, pyronaridine, for the treatment of uncomplicated malaria. Pyronaridine is a blood schizontocide that was first synthesized in China in 1970. Available data do not support international registration of the drug, yet they do indicate that it may be effective for the treatment of chloroquine-resistant malaria and that it is well tolerated after oral administration.

TDR is currently conducting a series of Phase I and IIa clinical trials with a newly designed capsule formulation of pyronaridine that has a better pharmacokinetic profile than the previously available tablet manufactured in China and coated for enteric absorption. These trials have been designed to characterize the pharmacokinetic profile, clinically effective dose, safety, and efficacy of the new capsule formulation of pyronaridine when used for the treatment of uncomplicated malaria. - From the TDR Newsletter 53, June 1997

Volunteer Opportunity: "HELP Congo"

"HELP Congo" ("Habitat Ecologique et Liberté des Primates") is a not-for-profit organization dedicated to the rehabilitation of ex-captive chimpanzees in the Conkouati Sanctuary, South Congo (near Pointe Noire). Since 1990, HELP has been taking care of seized orphan chimpanzees. Today, a total of 45 young chimpanzees are kept on several small islands and supplemented with food.

In November 1996, Caroline Tutin and other primatologists organized the first release operation. Seven chimpanzees were released into the Triangle area, a larger island with crossing paths to the main land, which already supports a small wild chimpanzee population. The released chimps were fitted with radio-collars, so their movements and basic activities can be monitored. HELP activities in the Coukouati Sanctuary also include a program of public awareness in the local communities (anti-poaching), the establishment of a tree nursery, and the development of ecotourism.

HELP is currently looking for volunteers to assist in various activities (ecological data collection on released chimpanzees, care of the 45 orphan chimps, public awareness and local capacity building, veterinary and administrative aspects, etc.). Volunteers may come for at least one month, but long-term involvements (3 months or more) are strongly encouraged. Background in primatology, eco-ethology, or telemetry and prior field work experience are preferred but not necessary. Volunteers must be able to cover their airfares and their living expenses in the Conkouati Sanctuary (allow US$900 per month).

HELP is also currently raising funds to purchase telemetry and forestry equipment for future release operations (US$5,500). Any suggestion on potential funding sources is welcome.

NAS Chimpanzee Committee Report

At the request of the National Institutes of Health, the Institute of Laboratory Animal Resources, National Acad-emy of Sciences (NAS), appointed 12 experts in biomedical research, colony management, demography, population genetics, conservation, and humane issues to provide recommendations on future scientific needs for chimpanzees in biomedical research and their long-term care.

Recommendations centered around: 1) the number of captive chimpanzees needed for future research and how they might best be provided; 2) the number of chimpanzees needed to provide offspring sufficient to meet future biomedical requirements and sustain a U.S. chimpanzee population; 3) options for long-term care and funding for chimpanzees no longer needed for research or breeding.

The committee also considered the following: population management strategies, including birth control and selective euthanasia; research with animals no longer needed for biomedical research; the role and mechanisms of non-government organizations in managing these animals; and the roles of both government and non-government agencies and institutions in providing support and funding for long-term care facilities.

The committee's report, Chimpanzees In Research: Strategies For Their Ethical Care, Management, And Use, were made public on July 16, 1997. The Committee suggests the existing chimpanzee population is more than adequate to meet research needs for at least five years. Moreover, increasing the number of chimpanzees maintained in the major NlH-supported biomedical chimpanzee facilities would risk eroding the quality of their care as a result of overcrowding, pressure on limited resources, and contamination of breeding and other research-naive animals by those used in infectious-disease studies. Therefore, the following recommendations were made:

(1) A breeding moratorium should be imposed for at least five years (1997-2001).

(2) Euthanasia should not be endorsed as a general means of population control.

(3) A core population of approximately 1,000 chimpanzees should be assured lifetme support by the federal government, and ownership of these animals should be transferred to the government.

(4) The concept of sanctuaries capable of providing for the long-term care and well-being of chimpanzees that are no longer needed for research and breeding should become an integral component of the strategic plan to achieve the best and most cost-effective solutions to the current dilemma.

(5) A single multiagency organized unit, the Chimpanzee Management Plan (ChiMP) should be established within the office of the Director of the National Institutes of Health, or as described below, and be given direct administrative and fiscal responsibility for government-owned animals that are considered necessary to meet current and long-term national needs.

(6) An appropriate advisory council of non-government experts should be created as a chartered committee for the purpose of establishing policies of ChiMP and for monitoring the short-term and long-term implications of these recommendations, including implications for research use, breeding colony size, demography, genetics, and long-term care.

Workshop Announcements: Methods and Techniques in Behavioral Research

Measuring Behavior `98, the second international workshop on measuring behavior, will address the integration of advanced behavioral research with physiological measurements. New developments both in the behavioral and physiological sciences make such an integration feasible. The development of techniques and generic software tools can form a bridge between disciplines, which are often unaware of techniques already available in other fields. For example, data analysis methods stemming from ethology are now being used by applied psychologists, and path analysis techniques originally designed by entomologists are proving useful for behavioral pharmacologists studying rodents. Moreover, recent developments in radiotelemetry, brain imaging, chip technology and biosensor techniques originally used by physiologists are now being used for simultaneous recording of physiological processes and behavior. The sponsors hope that Measuring Behavior `98, like Measuring Behavior `96, will serve as a common ground for crossfertilization of research disciplines.

Measuring Behavior `98 will be held in Groningen, The Netherlands, 18-21 August, 1998. It will consist of plenary sessions, demonstrations, training sessions, scientific tours, user meetings, etc. For further information, contact Measuring Behavior `98, Workshop Secretariat, Attn: Rosan Nikkelen, P.O. Box 268, 6700 AG Wageningen, The Netherlands [+31-(0)317-497677; fax: +31-(0)317-424496; e-mail:].

News Briefs

Project Betampona: Lemur Restocking Project

In cooperation with Malagasy authorities, the Madagascar Fauna Group, an international consortium of 30 zoological institutions, is moving forward with plans to re-stock black-and-white ruffed lemurs (Varecia variegata variegata) at the Natural Reserve of Betampona, a small (2228 ha) reserve in eastern Madagascar. Betampona is the sole forested mountain range in a vast region where eastern lowland forest has been lost to cultivation. A small Varecia population, at least eight other lemur taxa, and many bird, reptile, and other species will all benefit from increased protection brought by the project. Goals include the development and testing of reintroduction protocols for lemurs, and the integration of captive breeding programs with efforts to increase the viability of Betampona's remaining wild Varcia population. With preliminary behavioral, ecological, and genetic research completed and most of the necessary funds raised (funded in part by a grant from the Walt Disney World Company through AZA's Conservation Endowment Fund), captive-bred animals from the Ruffed Lemur Species Survival Plan population have been selected for release by the AZA Prosimian Advisory Group. Pairs have been formed and are now in "boot camp" at Duke University Primate Center and the Wildlife Conservation Society's St. Catherine's Wildlife Survival Center, located in Georgia, to prepare them for life in the wild. - From Endangered Species Update, March/April, 1997

Primate Imports in 1997 to Date

Shirley McGreal reported on Primate-Talk that IPPL had received from the U.S. Fish and Wildlife Service a list of live primate imports to the United States from 1 January-2 June 1997. "There may be other shipments not yet entered into the USFWS computer system. There were, according to USFWS, 28 shipments totalling 2691 primates valued at $3,255,124."

Primate Use in Fiscal Year 1996

The U.S. Dept. of Agriculture's FY96 Animal Welfare Enforcement Report indicates that 52,327 nonhuman primates were "in use" in laboratories during last fiscal year. This is to be compared with 55,113 in FY94 and 50,206 in FY95. The National Association for Biomedical Research, in reporting these figures, notes that an "accurate count of primates is difficult to obtain because they live long lives in captivity, and the same animals may be reported over and over from one year to the next."

Another Monkey Species Found in Brazil

A Dutch scientist has proven that a monkey species in the Brazilian rain forest is the world's second smallest monkey species.

A local man arrived at Marc Van Roosmalen's primate orphanage in Manaus, 1,800 miles northwest of Rio de Janeiro, in April, 1996, carrying a tiny monkey. It was mouse-size and greenish-gray, with white fringe around its face, a black crown, and a black tail. "As soon as I saw it I knew it was something new," Van Roosmalen said via telephone from Manaus.

Van Roosmalen identified the monkey as a black-headed Saguinus dwarf. To prove it was a new species, he needed to find a few more of them, but all he knew was that the monkey had been found on a boat on the Rio Madeira. After more than a year of hiking in the jungle, he located them near the Rio Aripuana.

DNA testing confirmed it was a new species in the Saguinus genus. The name Van Roosmalen used will stand until a full scientific description and formal name can be published; it is expected in the Brazilian journal Goeldiana later this year. - Associated Press, August 19, 1997

Fire in Poco das Antas Reserve

A raging fire has destroyed about one-sixth of the Poco das Antas nature reserve, which houses a colony of 350 endangered monkeys, ecologists in Brazil said on August 20. Some 700 hectares of the 5,000-hectare reserve had been destroyed by the blaze, putting at risk the entire population of rare golden lion-tamarins (Leontopithecus rosalia), many of which are descendents of monkeys born and raised in zoos. The nature park also houses other animal species, including birds, deer, lynx, otters, snakes, and sloths, as well as various native plants.

Park director Dionisio Pessamilio said arson is suspected. "Since spontaneous combustion is impossible, the only hypothesis is a criminal fire," Pessamilio said.

More than 50 firefighters tried to extinguish the fire, which broke out on August 18. Firefighters were assisted by workers from Brazil's Environmental Institute. The fire is the worst since 1,500 hectares of parkland in the Poco das Antas was destroyed in a 1991 blaze. - Posted to Primate-Talk by Robert Beale, from a report by Agence France Presse

Grants Available

Innovative Approaches to Develop New Technologies

The mission of the Biomedical Technology area of the National Center for Research Resources (NCRR) is to support research to identify, create and develop innovative technologies and to provide these technologies for biomedical research. Areas of emphasis are biomedical engineering, biomedical computing, and technologies for the study of structure and function at all levels of living systems. The purpose of this Program Announcement (PA) is to encourage submission of new Exploratory/Developmental Grant applications to explore new research paradigms in engineering, instrumentation, physical sciences, mathematics, or computer science as applied to biomedical research. The projects should provide the opportunity to develop new technologies, methods, devices, and materials that provide greater understanding of fundamental elements of biological phenomena. These efforts should lead to new approaches to the solution of basic research questions in order to prevent, diagnose, and treat disease and disability and ultimately to improve human health. The technologies/instruments/ methodologies to be developed under this program must be applicable to a variety of NIH research areas. Applications to develop technologies that apply only to one categorical NIH institute or a specific disease generally do not meet the guidelines for this program. Such applications will be considered only if the applicant clearly demonstrates the long-term potential of the technology for having a broad impact on biomedical research.

Application receipt date is October 17, 1997. The PA, which describes the research objectives, application procedures, review considerations, and award criteria for this program, may be obtained electronically through the NIH Grant Line (data line 301-402-2221), the NIH GOPHER (, the NIH Website <>, and by mail and email from Dr. Dov Jaron, Biomedical Technology, NCRR, 6705 Rockledge Dr., Rm 6160, MSC 7965, Bethesda, MD 20892-7965 [301-435-0755; fax: 301-480-3659; e-mail:].

Mucosal Immunity in Disease

The National Institutes of Health (NIH) invite applications for investigator-initiated basic and preclinical research into the human mucosal immune system and its regulation. Included are the gastrointestinal, oral, respiratory, reproductive, and urinary mucosa, with their specialized lymphoreticular structures and cells. The goal of this announcement is to increase high quality research on the mechanisms of response of the human mucosal immune system to disease-specific antigens. Use of primate models may be appropriate. Increased understanding of the human mucosal immune system and its response in disease and to exogenous factors should allow the design of more rational immunotherapies and vaccines for the treatment or prevention of autoimmune and infectious diseases, including HIV infection and its complications.

Novel HIV Therapies: Integrated Program

The Division of AIDS (DAIDS), National Institute of Allergy and Infectious Diseases (NIAID), invites applications for the discovery, preclinical evaluation, development, and/or pilot clinical study of novel agents and strategies to suppress HIV replication, interfere with disease progression, and ameliorate the consequences of infection. The National Institute of Mental Health invites applications to identify and treat the nervous system complications of HIV infection that result in CNS dysfunction. The Integrated Preclinical/Clinical Program (IPCP) described in this PA combines applications for the National Cooperative Drug Discovery Groups for the Treatment of HIV Infection, which supports preclinical discovery of new therapeutics; applications from collaborative groups seeking transition from preclinical to clinical studies during the award period; and applications for the Strategic Program for Innovative Research on AIDS Treatment, which supports pilot clinical studies of novel treatments. By combining these into a single PA, the IPCP will provide a continuous spectrum of research opportunities to groups interested in the discovery and development of new therapies for HIV infection. This PA is designed for multi-disciplinary preclinical and clinical research groups, each consisting of a minimum of three interrelated projects, in which the participation of the private sector is strongly encouraged. Responsive applications will involve creative and original therapeutic research that emphasizes diverse facets of HIV infection. Excluded from this PA are targets and approaches already under extensive investigation by academia and the pharmaceutical sector, non-targeted random screening of potential inhibitors, and research on AIDS-associated opportunistic pathogens and malignancies.

The preclinical portion of the IPCP supports the discovery and development of a specific therapeutic approach or strategy in a concerted manner with obvious contribution by and need for each project and core to the overall group objective and development plan. A successful preclinical group should develop a new therapeutic strategy that can subsequently be translated to clinical evaluation.

The National Institute on Drug Abuse (NIDA) will support innovative, integrated preclinical and clinical research to validate novel approaches and identify potential compounds that are safe and effective short-term (to reduce and stop cocaine and other psychomotor stimulants use) and long-term (to prolong abstinence) pharmacotherapies for the treatment of cocaine and other psychomotor stimulants addiction. A Strategic Program for Innovative Research on Cocaine (and other psychomotor stimulants) Addiction Pharmacotherapy can focus its therapeutic research activities on, for example, modulating specific receptor sites, (e.g., the dopamine transporter, D3 receptor, a serotonin receptor, etc,) or neurotransmitters that are believed to be involved in cocaine and other psychomotor stimulants addiction, or on development of biologically based anti-cocaine medications, such as antibodies, enzymes, and catalytic antibodies, or on advancing the neurobiological understanding of cocaine and other psychomotor stimulants addiction that will construct new therapeutic concepts. Studies should have a truly novel or innovative approach. This program complements existing, more traditional preclinical and clinical programs for the development of cocaine and other psychomotor stimulants treatment medications.

Research on Immune Tolerance

NIH invites applications that will elucidate basic mechanisms responsible for inducing and maintaining antigen-specific immune tolerance, that will facilitate translation of experimental knowledge on immune tolerance into clinical therapies for the treatment or prevention of immune-mediated disease, or that will promote more effective development of vaccines by preventing pathogen-induced immune tolerance.

Immunological Aspects of Hematopoietic Stem Cells

NIH invites applications for studies of the early stages of lymphoid lineage commitment and development from hematopoietic stem cells. Although much has been learned in recent years to enhance understanding of the later stages of T, B and natural killer (NK) cell development, definition of the complex processes that regulate lymphoid lineage commitment and early lymphoid progenitor cell differentiation requires expanded research efforts. Work in this area is expected to provide basic information needed for future applications to human immunodeficiency diseases, autoimmune diseases, hematopoietic stem cell transplantation, and gene transfer therapy.

Tuberculosis Research

The National Institute of Allergy and Infectious Diseases (NIAID) and National Heart, Lung, and Blood Institute (NHLBI), NIH, invite applications that propose to investigate the "latent" phase of infection by Mycobacterium tuberculosis (M.tb) and the mechanism(s) by which M.tb is reactivated in some hosts. For the purposes of this initiative, "the latent state" refers to that state of infection during which clinical disease is inapparent, yet infection of the host has been established. The mechanisms by which this phase terminates in some hosts and persistent bacilli are re-activated, leading to development of active disease, are also of interest.

Chemical Modifiers: Radiation Response of Tumors

The Division of Cancer Treatment, Diagnosis, and Centers (DCTDC) of the National Cancer Institute (NCI) invites research grant applications from interested investigators for preclinical exploration of the therapeutic potential of new and novel chemical modifiers of radiation response of tumors. Optimization of leads arising from the applicant's own work or from the published literature should include the design and synthesis of new compounds, using combinatorial chemistry, and preclinical evaluation in vitro and in vivo.

Application receipt dates are October 1, February 1 and June 1. For more information, contact Helen B. Stone, DCTDC, NCI, 6130 Executive Blvd, Suite 800, Bethesda, MD 20892-7440 [301-496-9360; fax: 301-480-5785; e-mail:].

Antigen Recognition in Allograft Survival

The National Institutes of Health invite applications for studies to further our understanding of the immune response to direct or indirect presentation of allogeneic major histocompatibility complex (MHC) antigens and to determine the contribution of each pathway to acute and chronic graft rejection. Research to date has focused on direct recognition of allogeneic MHC; therapies designed to block this pathway have been successful in reducing acute rejection of transplanted organs. However, chronic rejection is still an impediment to long-term survival. The indirect pathway of allorecognition has recently been implicated primarily in chronic graft rejection; however, an additional role for this pathway in the enhancement of acute rejection has been suggested. Knowledge from basic, preclinical and clinical studies aimed at characterizing the relative role of the direct and the indirect allorecognition pathways in enhancing or preventing graft rejection could lead to the development of specific interventions to modulate immune recognition after transplantation and ultimately increase graft survival.

Minor Histocompatibility Antigens

NIH invites applications for studies to further our understanding of the role of minor histocompatibility antigens (MiHA) in graft vs. host disease (GVHD) following bone marrow transplantation and the possible involvement of MiHAs in chronic graft rejection of solid organ transplants. Most of the research efforts to date have centered on the role of the major histocompatibility complex (MHC) antigens in rejection of transplanted tissues and organs. This Program Announcement is directed at characterizing the immunologic response to MiHA and at defining the manner and extent to which that response affects successful long-term engraftment. The immune response to MiHA is a major, if underappreciated, cause of graft failure in bone marrow transplantation. This initiative is designed to promote research to characterize the immunologic response to MiHA, and to attempt to define how that response can be prevented to enhance graft survival. It will support basic, pre-clinical, and clinical studies using molecular and cellular approaches to dissect the immune response to these antigens. These studies may lead to new information with the potential for clinical applications thereby improving long-term graft survival in bone marrow and solid organ transplant recipients.

Innate Immunity

The National Institute of Allergy and Infectious Diseases (NIAID) and the National Institute of Dental Research (NIDR), National Institutes of Health (NIH), invite applications for research studies of the innate immune system. Two general systems of immune recognition have been selected through evolution: innate immunity and acquired immunity. The innate immune system provides broad, but relatively nonspecific host defenses that lack the properties of antigenic specificity and immunologic memory that characterize acquired immunity. However, recent discoveries point to many robust mechanisms of innate immunity and have highlighted important functional links between the innate and acquired immune responses. The purpose of this announcement is to support basic and preclinical studies of the mechanisms of innate immunity in order to: a) develop new strategies to augment antimicrobial defenses; b) develop novel approaches for immunomodulation in chronic infectious and inflammatory disorders; and c) identify new methods, based on mechanisms of innate immunity, to modulate acquired immune responses (e.g., to enhance vaccine efficacy).

Immune Response to Xenotransplant Antigens

The National Institute of Allergy and Infectious Diseases (NIAID), National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), and National Heart, Lung and Blood Institute (NHLBI) invite applications to enhance our ability to transplant organs and tissues across species barriers (xenotransplantation) by increasing our understanding of the human immune response to antigens present on the surface of organs or tissues from nonhuman species, and the development of methods to allow rapid identification and treatment of infectious diseases that might occur by transmission of disease-causing organisms across species barriers. This research would lead to the development of new therapies to allow xenografts to survive and function in humans and the generation of new, sensitive detection methods to decrease the risk of infectious disease associated with xenotransplantation.

Anatomy & Physiology

* Hormonal response to restraint in rhesus monkeys. Gauquelin-Koch, G., Blanquie, J.-P., Viso, M., Florence, G., Milhaud, C., & Gharib, C. (C. G., Lab. Physiol. de l'Environ., Fac. de Méd. Lyon Grange-Blanche 8, Ave. Rockefeller, 69373 Lyon cedex 08, France). Journal of Medical Primatology, 1996, 25, 387-396.
. . . Blood-volume-regulating hormones were measured in four adult male monkeys during (1) 10 days in a metabolic cage; (2) 16 days restrained in a metabolism chair; and (3) 10 days in the metabolic cage. An increase of active renin (30%) and vasopressin (25%) was observed at the end of (2). A decrease of atrial natriuretic peptide, urodilatin, and Na excretion occurred during the first days of (2). A dramatic increase (tenfold) in urinary excretion of growth hormone occurred during all of (2) and the beginning of (3).

* Development of spontaneous endometriosis in baboons. D'Hooghe, T. M., Bambra, C. S., Raeymaekers, B. M., & Koninckx, P. R. (Dept of Ob/Gyn, University Hospital Gasthuisberg, B-3000 Leuven, Belgium). Obstetrics & Gynecology, 1996, 88, 462-466.
. . . Twenty-four baboons with laparoscopically confirmed normal pelves underwent laparoscopies over 32 months. The cumulative incidence of minimal endometriosis (proven by histology) was 64% up to 32 months of follow-up. The 8 baboons that developed proven endometriosis were followed over longer periods of time and had undergone more laparoscopies than the animals that did not develop the condition.

Animal Models

* Isolated cerebral hypothermia by single carotid artery perfusion of extracorporeally cooled blood in baboons. Schwartz, A. E., Stone, J. G., Finck, A. D., Sandhu, A. A., Mongero, L. B., Adams, D. C., Jonassen, A. E., Young, W. L. & Michler, R. E. (Dept of Anesthesiology, Box 46, College of Physicians & Surgeons, Columbia Univ., 630 W. 168th St, New York, NY 10032). Neurosurgery, 1996, 39, 577-582.
. . . Bilateral cerebral deep or moderate hypothermia can be induced by selective perfusion of a single internal carotid artery, with minimal systemic cooling and without cardiovascular instability. This global brain hypothermia results from profoundly altered collateral cerebral circulation during artificial hypothermic perfusion.

* Antibodies against CD14 protect primates from endotoxin-induced shock. Leturcq, D. J., Moriarty, A. M., Talbott, G., Winn, R. K., Martin, T. R., & Ulevitch, R. J. (Johnson Pharm. Res. Inst., 3535 General Atomics Ct, San Diego, CA 92121). Journal of Clinical Investigation, 1996, 98, 1533-1538.
. . . Lipopolysaccharide (LPS), residing in the outer membrane of gram-negative bacteria, is considered a major initiating factor of gram-negative septic shock syndrome in humans. LPS forms a complex with binding protein in plasma, which engage a specific receptor, CD14, on the surface of myeloid cells, leading to the production of potent proinflammatory cytokines. Cynomolgus monkeys were treated with one of two different inhibitory anti-CD14 mAbs, then challenged with intravenous endotoxin. The anti-CD14 treatment regimens were successful in preventing profound hypotension, reducing plasma cytokine levels, and inhibiting the alteration in lung epithelial permeability that occurred in control animals.

* Fecal short-chain fatty acids associated with inflammation in cotton-top tamarin model for idiopathic colitis. Stonerook, M. J., Tefend, K. S., Sharma, H. M., Peck, O. C., & Wood, J. D. (J. D. W., Dept of Physiology, College of Med., Ohio State Univ., 300 Hamilton Hall, 1645 Neil Ave, Columbus, OH 43210). Digestive Diseases & Sciences, 1996, 41, 1618-1624.
. . . Tamarins with moderate or severe colitis had significantly reduced levels of fecal short-chain fatty acids.

* IL-4 induced leucocyte trafficking in cynomolgus monkeys: Correlation with expression of adhesion molecules and chemokine generation. Gundel, R., Lindell, D., Harris, P., Fournel, M., Jesmok, G., & Gerritsen, M. E. (Preclinical Research, Bayer Corp., 400 Morgan Lane, West Haven, CT 06516). Clinical & Experimental Allergy, 1996, 26, 719-729.
. . . Interleukin-4 (IL-4) induces a selective recruitment of lymphocytes from the vasculature while the number of neutrophils are increased in the circulation. IL-4 treatment caused the percentage of CD16+ cells in the circulation to decrease and induced a rapid and sustained increase in hematocrit. IL-4 induced the expression of vascular cell adhesion molecule-1 (VCAM-1) on the surface of the endothelium and caused a dramatic increase in plasma levels of MCP-1. IL-4 may have a primary role in the early selective recruitment of lymphocytes to sites of tissue inflammation by the induction of VCAM-1 and the release of large amounts of potent chemoattractants, and may represent a target in the development of new therapeutics for the treatment of inflammatory disease.

* Immune response to epitopes of hepatitis C virus (HCV) structural proteins in HCV-infected humans and chimpanzees. Wang, Y.-F., Brotman, B., Andrus, L., & Prince, A. M. (A. M. P., Lab. of Virology & Parasitology, New York Blood Ctr, 310 E. 67th St, New York, NY 10021). Journal of Infectious Diseases, 1996, 173, 808-821.
. . . The patterns of immune response in HCV-infected humans and chimpanzees were in many ways dissimilar in terms of antibody response to HCV capsid and GOR epitopes and reactivity with different linear epitopes on HCV E2.

* Respiratory effects of opioid full and partial agonists in rhesus monkeys. Libuori, A., Morse, W. H., & Bergman, J. (Harvard Med. School, NERPRC, Box 9102, 1 Pine Hill Dr., Southborough, MA 01772-9102). Journal of Pharmacology & Experimental Therapeutics, 1996, 277, 462-472.
. . . Respiratory and behavioral effects of the -selective opioids levorphanol, methadone, and codeine and the mixed-action opioids buprenorphine, butorphanol, and nalbuphine were studied in awake, seated rhesus monkeys wearing plastic masks through which they breathed air or differing concentrations of CO2 mixed in air. All opioids produced dose-dependent decreases in ventilation that were more pronounced as the concentration of CO2 increased. In behavioral experiments, all drugs produced dose-related decreases in responding under a 30-response fixed-ratio schedule.

* Vaccine protection by a triple deletion mutant of simian immunodeficiency virus. Wyand, M. S., Manson, K. H., Garcia-Moll, M., Montefiori, D., & Desrosiers, R. C. (R. C. D., Address same as above). Journal of Virology, 1996, 70, 3724-3733.
. . . Twelve rhesus monkeys were vaccinated with SIVmac316nef (lacking nef sequences), and 12 were vaccinated with SIVmac2393 (lacking nef, vpr, and upstream sequences in U3). Seventeen of the animals developed persistent infections with the vaccine viruses. Seven, however, developed infections that were apparently transient in nature. Six of these yielded virus from peripheral blood when tested at weeks 2 and/or 3, three had transient antibody responses, but none had persisting antibody responses. All 24 monkeys were challenged with 10 rhesus monkey infectious doses of wild-type, pathogenic SIVmac251 at weeks 8, 20, and 79 following receipt of vaccine. None of the 7 with apparently transient infections were protected upon subsequent challenge. Analysis of cell-associated viral loads, CD4+ cell counts, and viral gene sequences in the remainder of the monkeys led to these conclusions: 1) There was a trend toward increased protection with length of time of vaccination. 2) Solid vaccine protection was achieved by 79 weeks with the highly attenuated SIV2393. 3) Solid long-term protection was achieved in at least 2 animals in the absence of complete sterilizing immunity. 4) Genetic backbone appeared to influence protective capacity: animals vaccinated with SIV2393 were better protected than animals receiving SIV316nef. 5) The titer of virus-neutralizing activity in serum on the day of challenge correlated with protection when measured against a primary stock of SIVmac251, but not when measured against a laboratory-passaged stock.

* Recombinant subunit vaccines as an approach to study correlates of protection against primate lentivirus infection. Hu, S.-L., Polacino, P., Stallard, V., Klaniecki, J., Pennathur, S., Travis, B. M., Misher, L., Kornas, H., Langlois, A. J., Morton, W. R., & Benveniste, R. E. (Bristol-Myers Squibb Pharm. Res. Inst., 3005 First Ave, Seattle, WA 98121). Immunology Letters, 1996, 51, 115-119.
. . . Envelope gp160 vaccines, when used in a live recombinant virus-priming and subunit-protein-boosting regimen, protected long-tailed macaques against low-dose intravenous infection by a cloned homologous virus SIVmne E11S. The same regimen was also effective against intrarectal challenge by the same virus and against intravenous challenge by E11S grown on primary macaque peripheral blood mononuclear cells. However, only limited protection was observed against uncloned SIVmne. Priming with live recombinant virus was more effective than immunization with subunit gp160 alone, indicating a potential advantage of native antigen presentation and the possible role of cell-mediated immunity in protection. Whole gp160 was more effective than the surface antigen (gp130), even though both antigens elicited similar levels of neutralizing antibodies. These and other results indicate that multiple mechanisms may contribute to protection. It may be advantageous to incorporate multiple antigens in the design of recombinant subunit vaccines against AIDS.

Animal Welfare

* Videostimulation as enrichment for captive rhesus monkeys (Macaca mulatta). Platt, D. M. & Novak, M. A. (Behavioral Biology, NERPRC, One Pine Hill Dr., Southborough, MA 01772). Applied Animal Behaviour Science, 1997, 52, 139-155.
. . . Nine monkeys were exposed to 5 experimental phases: no monitor, blank monitor, videotape, blank monitor, and video game. Monkeys both watched selected videotapes and manipulated the video game joystick, but they spent substantially more time watching tapes than manipulating the joystick, and females were more interested in both than were males. Both socially and individually housed monkeys became more active; individually housed monkeys slept less.


* Seasonal trends in intestinal nematode infection and medicinal plant use among chimpanzees in the Mahale Mountains, Tanzania. Huffman, M. A., Gotoh, S., Turner, L. A., Hamai, M., & Yoshida, K. (Primate Res. Inst., Kyoto Univ., Kanrin, Inuyama, Aichi 484, Japan). Primates, 1997, 38, 111-125.
. . . The incidence of nematode infections was analyzed, over two annual dry and rainy season periods and a third rainy season, for seasonal trends to elucidate the possible influence of parasite infection on previously reported seasonality of medicinal plant use. Observations were consistent with previous reports for increased use of these plants during the rainy season and with the hypothesis that use of the plants is stimulated by presence of parasites.

* Immigration in wild groups of golden lion tamarins (Leontopithecus rosalia). Baker, A. J. & Dietz, J. M. Philadelphia Zoo, 3400 W. Girard Ave, Philadelphia, PA 19104). American Journal of Primatology, 1996, 38, 47-56.
. . . Seventeen territorial groups of wild golden lion tamarins were monitored for 10 to 76 months. Immigration into established groups was rare and occurred mostly in the context of replacement of breeding individuals. Aggression by resident tamarins toward potential immigrants appeared to be the proximate factor limiting movement into groups. Most such aggression was intrasexual, but potential female immigrants were sometimes chased by male as well as female residents. Immigration was highly male-biased (85% of individuals). Factors possibly contributing to this bias were inheritance of breeding positions by adult daughters, ability of males but not females to join groups already containing a same-sex breeding individual, and the fact that potential female immigrants appeared to face some intersexual as well as intrasexual aggression.

* Adsorptive capacity of charcoals eaten by Zanzibar red colobus monkeys: Implications for reducing dietary toxins. Cooney, D. O. & Struhsaker, T. T. (Dept of Chem. Engineering, Univ. of Wyoming, Laramie, WY 82071). International Journal of Primatology, 1997, 18, 235-246.
. . . Colobus monkeys on Zanzibar eat charcoal from burned trees and lying near kilns. Charcoal from burned stumps and from kilns were compared with commercial activated charcoals for their ability to adsorb organic material. The charcoal from kilns compared well to the commercial product, supporting the hypothesis that the monkeys have learned to eat it to counteract toxicity due to phenolic and similar compounds that occur in significant concentrations in the Indian almond and mango leaves which constitute a major part of their diet.

Development and Aging

* Characterization of dermatologic changes in geriatric rhesus macaques. Huneke, R. B., Foltz, C. J., VendeWoude, S., Mandrell, T. D., & Garman, R. H. (Wash-ington Univ. School of Med., Div. Comp. Med., 660 S. Euclid Ave, Campus Box 8061, St. Louis, MO 63110). Journal of Medical Primatology, 1996, 25, 404-413.
. . . Skin and blood samples from 9 geriatric animals (mean age = 25 yr) were examined and compared with those of control adult (mean age = 10 yr) and sun-exposed (mean age = 11 yr) animals. Major gross findings included increased areas of erythematous skin, wrinkling, focal skin scaling, thinning of hair, foot calluses, and exudative lesions. Histologic skin changes included subacute dermatitis, acanthotic dermatitis, and a lesion resembling an early solar lentigo in the sun-exposed animal. These changes were not associated with hormonal abnormalities or bacterial pathogens. Histologic changes are compatible with nonspecific skin changes observed in elderly humans.

* Age-related changes in ovarian morphology from birth to menopause in the Japanese monkey, Macaca fuscata fuscata. Nozaki, M., Yamashita, K., & Shimizu, K. (Sado Marine Biol. Station, Niigata Univ., Sado, Niigata 952-21, Japan). Primates, 1997, 38, 89-100.
. . . Ovarian morphology was studied in 47 nonlactating females of various ages, ranging from newborn to 28 years. Ovary size increased during the first decade of life, reached a plateau around 10 years, and declined gradually thereafter. The ovarian cortex of newborn animals consisted of numerous clusters of mitotic primordial germ cells, which were found up to 28 days of age. Corpora lutea or corpora albicantia were found in ovaries more than 4 years old, while remnants (together with thick-walled blood vessels and fibrosis) appeared in some ovaries after 16 years and were observed in most after 26 years of age.


* Gongylonematiasis in the common marmoset (Callithrix jacchus). Brack, M. (Deutsches Primatenzentrum, Abt. Pathologie u. Tierärz. Versorgung, 37077 Göttingen, Ger-many). Laboratory Animal Science, 1996, 46, 266-270.
. . . Two cases of gongylonematiasis in marmosets at two research facilities in Germany are reported. The hel-minthiasis was transmitted from colony A to colony B by one infected female and within colony B by cockroaches. Clinical signs of disease in the infected animals consisted of intense itching and scratching of the edematous and slightly hyperemic perioral tissues. Histologically the adult helminths lodged predominantly in the mucous membranes of the upper and lower lips; less frequently in the labial cutaneous parts or in the tongue.

* Hemorrhagic typhlocolitis associated with attaching and effacing Escherichia coli in common marmosets. Thomson, J. A. & Scheffler, J. J. (Wisconsin RPRC, Univ. of Wisconsin, 1223 Capitol Ct, Madison, WI 53715-1299). Laboratory Animal Science, 1996, 46, 275-279.
. . . Three common marmosets were necropsied during an outbreak of hemorrhagic diarrhea in a colony of 230 animals. Necropsy revealed consistent hemorrhagic typhlocolitis and variable ileitis associated with gram-negative bacilli closely adherent to enterocytes. Electron microscopy revealed bacilli attached intimately to shallow cup-like projections of enterocyte apical membranes with loss of microvilli. E. coli isolates from affected marmosets were serogroup O26 and were positive for the E. coli attaching and effacing locus and negative for shiga-like toxin I and II, heat-stable enterotoxins a and b, and heat-labile enterotoxin by DNA probe hybridization.

* Colonic adenocarcinoma in a rhesus macaque (Macaca mulatta). Johnson, E. H., Morgenstern, S. E., Perham, J. M., & Barthold, S. W. (Dept of Animal & Vet. Sci., College of Agriculture, Sultan Qaboos Univ., P.O. Box 34, Al-Knod, Postal Code 123, Muscat, Sultanate of Oman). Journal of Medical Primatology, 1996, 25, 435-438.
. . . A spontaneous colonic adenocarcinoma and endometriosis was diagnosed in a 34-year-old female macaque. The tumor caused partial obstruction of the ascending colon and histologically resembled the commonly described "napkin-ring" tumors of the descending and sigmoid colon found in humans. Serum levels of CA 125, a high-molecular-weight glycoprotein antigen that has been reported elevated in a variety of pathological conditions of the pelvic cavity in humans, was severely elevated. Both the adenocarcinoma and the endometriosis may have contributed to this finding.

* Simian immunodeficiency virus infection in a patas monkey (Erythrocebus patas): Evidence for cross-species transmission from African green monkeys (Cercopithecus aethiops sabaeus) in the wild. Bibollet-Ruche, F., Galat-Luong, A., Cuny, G., Sarni-Manchado, P., Galat, G., Durand, J.-P., Pourrut, X., & Veas, F. (Lab. Rétrovirus, ORSTOM, 911 Ave. Agropolis, BP 5045, 34032 Montpellier cedex 1, France). Journal of General Virology, 1996, 77, 773-781.
. . . Physical contact has been documented between African green monkeys (AGMs) and patas monkeys. Elevated SIV seroprevalence rates have been reported for AGM species. Among 85 AGMs and 54 patas monkeys studied, 47% and 7.5%, respectively, had antibodies that cross-reacted with HIV-2 envelope proteins. From two AGMs a virus was isolated; from the patas monkeys, virus isolation was generally not possible, but from an ill animal a virus designated pamG31 was amplified by polymerase chain reaction (PCR). For the two SIVagm isolates, an 830 bp region spanning the env and nef genes was amplified and sequenced. Comparisons of sequences from the env/nef region revealed 80% identity between pamGT31 and SIVagm isolates from AGMs of the sabeus subspecies, and 94% identity between the two SIVagm isolates. This is the first report of a lentiviral infection in a patas monkey.

* Genetic diversity of simian immunodeficiency viruses from West African green monkeys: Evidence of multiple genotypes within populations from the same geographical locale. Bibollet-Ruche, F., Brengues, C., Galat-Luong, A., Galat, G., Pourrut, X., Vidal, N., Veas, F., Durand, J.-P., & Cuny, G. (Address same as above). Journal of Virology, 1997, 71, 307-313.
. . . Genetic diversity of the SIV viruses found in various AGM subspecies far exceeds the diversity observed in the other lentivirus-infected human and nonhuman primates and is thought to reflect ancient introduction of SIV in the AGM population. This paper investigates genetic diversity of SIVagm in wild-living AGM populations from the same geographical locale in Senegal. For 11 new strains, two regions of the genome spanning the first tat exon and part of the transmembrane glycoprotein were PCR-amplified and sequenced. Phylogenetic analysis of these sequences shows that viruses found in sympatric populations cluster into distinct lineages, with at least two distinct genotypes in each troop, suggesting an ancient introduction of these divergent viruses in the AGM population.

* SIVagm infection of its natural African green monkey host. Norley, S. G. (Paul-Ehrlich-Inst., Paul-Ehrlich-Str. 51-59, 63225 Langen, Germany). Immunology Letters, 1996, 51, 53-58.
. . . Possible reasons for the apathogenicity of SIVagm in its natural AGM host were investigated. The level of infection in the peripheral blood was reminiscent of the level in asymptomatic HIV-1-infected patients, although never reaching the levels associated with AIDS. Like humans, AGM CD8+ cells secrete a factor able to suppress SIVagm (and HIV-1) replication but, unlike humans, AGMs have a very high percentage of CD8+ lymphocytes in circulation. Also, unlike humans during the asymptomatic stages of infection, AGM lymph nodes do not seem to act as a reservoir for SIVagm and the lymph node structure is not affected.

* Characterization of transgenic pigs expressing functionally active human CD59 on cardiac endothelium. Diamond, L. E., McCurry, K. R., Martin, M. J., McClellan, S. B., Oldham, E. R., Platt, J. L., & Logan, J. S. (Nextran, 303B College Rd East, Princeton, NJ 08540). Transplantation, 1996, 61, 1241-1249.
. . . Using specific lines of transgenic pigs that express low levels of human CD59, a complement regulatory protein that acts at the terminal stage of the complement cascade, evidence is presented that shows that the human CD59 protein inhibits assembly of the membrane attack complex and reduces tissue damage when the heart is transplanted to a baboon.
