Indonesia’s Intricacies: Rhinos, Lorises, and a Dab of Dengue

View along the way to International Animal Rescue – Bogor

When one thinks of Indonesia, picturesque scenes of Bali’s beaches or bold batik patterns might come to mind. Indonesia has an entirely different meaning to me, as this archipelago constitutes one of the most biodiverse regions on the planet. Amidst the dense rainforest foliage are fascinating endemic species, but given threats from habitat loss and poaching, the future of some Indonesian species remains uncertain. In particular, Javan and Sumatran rhinoceroses exist in a precarious state, being some of the most endangered mammals in the world. Last summer, I had the privilege of traveling to Indonesia with Carmen Smith (DVM 2021) and Montana Stone (BS 2019), under the guidance of Dr. Robin Radcliffe and support from Expanding Horizons and Engaged Cornell, to partake in a multi-faceted program centered around international conservation efforts.

Building upon Dr. Radcliffe’s well-established relationships with partners in Indonesia, we were warmly welcomed by personnel from WWF-Indonesia, who had created a summer schedule with the goal of exposing us to different components of conservation work. First, we headed to the buffer zone of Ujung Kulon National Park, the last habitat of the Javan rhino. We assisted a group known as Sekala Petualang as they led conservation education programs for local school children where mainly Indonesian was spoken. It became quickly apparent that the weekly Indonesian classes we took during the spring semester before leaving were my only saving grace in that remote part of Indonesia (where cellular signals are nonexistent). Environmental stewardship was the underlying theme to the program, as educating children is an effective way to create a conservation-embracing culture. Despite living alongside a national park with Javan rhinos, a number of children were unaware that such an animal even existed in their “backyard”. It was heart-warming to see that the kids had open and receptive minds. One of Carmen’s presentations introduced veterinary medicine, yet another unfamiliarity that intrigued them. This segment of the summer underscored the importance of engaging with communities, walking in their shoes, and creating a space conducive for exchanging ideas bidirectionally. 

The next portion of the summer was spent at Institut Pertanian Bogor, a prominent university, which brought us back to the hustle and bustle of Indonesia’s urban scene. The crux of Carmen’s Expanding Horizon’s project was investigating rhino pathology as a means to better inform rhino conservation initiatives. The pathology faculty were very generous with their samples, taking us through both Javan and Sumatran rhino mortality cases. Despite my ineptitude with pathology, I was able to gain an appreciation for the challenges pathologists face working with wildlife species. I soon learned what the word “autolysis” meant as we scanned each image from the necropsy; imagine the difficulty of mobilizing a team of pathologists that must trek with their supplies to remote sites within the rainforest, finally laying their hands on the deceased rhino more than a day post-mortem, precious tissues vulnerable in the incessant Indonesian heat.

Ultimately, Carmen and I were able to translate pathology reports into English to increase their accessibility, perform literature reviews, and identify topics worthy of discussion for a scientific publication. We realized that while individuals may have a species’ best interest in mind, other parties are bound to have conflicting interests or political underpinnings that ultimately jeopardize cohesive collaborations between various conservation organizations. We learned that any work of such nature, especially in a foreign country, must be done with exacting precision and respect. This chapter of the summer would be incomplete without mentioning my bout with dengue fever, which actually made me miss a portion of the pathology work. What started as a simple cough turned into body aches, fever, inappetence, and more. I figured an illness was inevitable in a novel tropical country, so I thought this was normal (despite running out of all of my pain medication trying to ease the symptoms). Soon thereafter, Montana also fell ill with dengue, at which point I was tested. Although no one heads off to international experiences with the intention of contracting a mosquito-borne disease, the experience was a lesson in resilience and preparedness. After all, despite being ill, I was unable to turn down a day trip to Taman Mini, a phenomenal bird park!

Prior to the next portion of the program, we briefly visited an illegal pet market, which unnerves me still to this day. I had a mental image of what such a market would entail, though nothing could have prepared me for the true horror I saw. Densely packed cages teeming with stressed birds (not to mention the dead birds littering the cage bottoms) were interrupted by cages of civets, flying foxes, macaques, and more. My heart ached for the bird that would not live to see another sunrise, for the listless civet lying motionless in its cage, and for the chained baby macaque tucked away in the shadows. I felt defeated, but I realized that such scenes are the very essence of what drives me and many other veterinary students to pursue careers that contribute to the conservation of wildlife. This experience solidified why educating the next generation on the importance of conservation and environmental stewardship is essential. 

Routine health assessment of a Javan slow loris at IAR

With the atrocities from the market still fresh on our minds, Carmen and I went to International Animal Rescue – Bogor, a site that primarily focuses on rescue, rehabilitation, and release of Javan and Sumatran slow lorises. Lorises are common in the wildlife trade, and in the markets, their canines are clipped, setting the stage for dental and subsequent metabolic disease. A number of the lorises we worked with were non-releasable, so the rescue exceeded twice its anticipated capacity. We engaged in loris husbandry, spent nights observing lorises (an experience unlike any other!), and helped with their veterinary care. Multiple patients illustrated the harsh reality of a fragmented habitat. The mere existence of a road bordered by uncoated electrical wires poses a great threat to unsuspecting lorises attempting to cross the road. The prognosis is often bleak for the few lorises that manage to survive electrocution. This experience solidified my understanding of the human/wildlife dynamic, which tragically tends to swing in favor of the former.

Carmen, Montana, and Alex at Kelian Sanctuary, Borneo

Habitat loss and fragmentation set the stage for the next experience that brought us to Kelian Sanctuary in Borneo. The previous year, a Sumatran rhino named Pahu was rescued from the wild and brought to the sanctuary. Pahu is possibly only one of three rhinos remaining of her subspecies, so it is of utmost importance to rescue these isolated animals and investigate breeding options. There are Sumatran rhinos (Sumatran subspecies) that reside at the Sumatran Rhino Sanctuary in Sumatra, so collaboration is anticipated in an attempt to save this species overall. As we landed in Borneo in a precarious propellor plane, the three of us were riddled with excitement. In the few days we had at Kelian, the team composed of individuals from WWF-Indonesia and ALeRT completely immersed us in the operations at the sanctuary. Before I knew it, I was hand feeding Pahu various plants, watching her veterinary examinations and procedures, and observing her in her paddock. It was at that moment that it was clear to me that megafauna like the Sumatran rhino simply cannot be lost from this planet—it is our duty to fight with all of our passion and intensity to save such species before they slip away. Even when I was out with the team collecting food for Pahu or planting trees in the rainforest, I embraced the physical and acoustic beauty of the surrounding rainforest. During patrols of Pahu’s paddock, I witnessed gibbons, macaques, hornbills, and even a clouded leopard. During this time, Montana was able to train personnel at the sanctuary to utilize a Cornell Lab of Ornithology Swift recorder to document Pahu’s vocalizations, as no bioacoustical analysis had previously been done on Sumatran rhinos. To this day, I treasure hearing a content Pahu wallowing in the mud, “humming” and producing kazoo-like sounds, and I hope that one day everyone will know of this rhino’s plight and hear their delightful vocalizations.

As I write, I wonder whether that was my first and last time working with a Sumatran rhino. Let me re-phrase that—will the next generation even learn of critically endangered species like the Indonesian rhinos or will the species’ names be relics of a bygone era? Questions like these serve as an impetus for my passion in conservation medicine. My time in Indonesia helped me grasp what international conservation work entails, exposed me to the associated difficulties, all while leaving me inspired. I met some of the most passionate individuals in Indonesia, so I have faith that my previous questions will have favorable responses decades from now.

The Cheetah Chronicles: An Introduction

Greetings from Otjiwarongo, Namibia! My name is Elvina Yau and I am a rising 3rd year veterinary student at Cornell. My professional interests are quite varied, as I enjoy Small Animal Medicine, practice ownership, and wildlife conservation. Although companion animals and wildlife seem like disparate fields, there are pragmatic overlaps between the two disciplines that nonetheless require the advocacy of any aspiring veterinarian. I first participated in the Expanding Horizons program last summer, a formative experience studying Asian elephant welfare in Chiang Mai, Thailand. In order to further increase my exposure to wildlife species and international veterinary medicine, I am currently pursuing my second Expanding Horizons opportunity here in Namibia, Africa.

This summer, I have partnered with the AfriCat Foundation to conduct research on cheetah nutrition. Located on the Okonjima Nature Reserve, AfriCat is a non-profit organization established in 1993 whose mission is to promote the long-term conservation of large carnivores through education and research. According to the IUCN Red List, cheetahs are listed as Vulnerable. Namibia has the largest global population of roughly 2000 wild cheetahs, 90% of which can be found on livestock and game farms throughout the country. Since felids are predators that require large habitats and the majority of cheetahs live on commercial farmland, human-wildlife conflict often arises due to overgrazing from cheetahs and retaliatory killing by farmers. Clearly, transboundary conservation initiatives are needed to improve tolerance and livestock management at the human-wildlife interface, reform regional policy and legislation, and increase education at all levels of society in order to sustain a viable population of cheetahs.

My project specifically investigates the clinical, metabolic, and behavioral effects of glycine supplementation in cheetahs. The resident cheetahs at AfriCat are rescued from commercial farmland across Namibia, and are housed in spacious enclosures of 12-50 acres. Nutritional disease—namely glycine deficiency—is a prevalent health concern seen in captive and semi-free ranging cheetahs. Normally, cheetahs in the wild have a high dietary intake of glycine obtained through consumption of the carcass components of their prey, which supply rich sources of this amino acid. Glycine is a precursor for several important biomolecules such as DNA, creatine, bile acids, and glutathione (a major intracellular antioxidant). Glycine also plays a critical role in anti-inflammatory responses, neurological function, detoxification of organic acids, and maintainance of connective tissue integrity.

Although cheetahs can synthesize glycine from other amino acids like serine or threonine, this biochemical pathway is inefficient, and endogenous synthesis of glycine does not fully meet metabolic demand. While a mild insufficiency is tolerable, a chronic deficiency can be profoundly detrimental to the animal’s growth, immune response, and metabolism. Considering glycine’s properties and therapeutic benefits, our study seeks to supplement an appropriate glycine dose to the cheetahs’ diets to assess whether it is clinically promising towards their health and well-being.

Feeding trials will be conducted with sub-adult cheetahs by adding a glycine powder supplement to their standard diet for 4 weeks. Before the trial commences, each cheetah will be anesthetized to collect baseline data and samples (e.g. urine, blood). Hematology, serum chemistry panels, and urinalysis will be conducted on each cat to measure metabolites and physiological parameters like electrolytes and cortisol levels. Furthermore, abdominal ultrasounds will be performed and flexible endoscopes will be used in order to obtain gastric biopsies from each cheetah. After the 4-week trial, the cheetahs will again be anesthetized and endoscoped to collect another round of biological samples so we can compare pre- and post-glycine data. During the study, the cheetahs will also have their activity levels monitored to assess for any changes in behavior or sleep patterns. Since glycine is an inhibitory neurotransmitter, a potential side effect of dietary supplementation could be increased drowsiness.

Our dietary trials can thus illuminate the precise metabolic profile of cheetahs and test whether a glycine powder supplement helps improve the pathological conditions associated with glycine deficiency. By providing further insight into this unique and less understood aspect of carnivore health, our goal is to advance understanding of the metabolic alterations associated with malnutrition and intestinal dysbiosis, and hopefully develop a safe, inexpensive form of nutritional intervention.

Through Expanding Horizons, I am spending eight weeks in Namibia, where I can intimately experience the vibrant fauna and flora of the Okonjima Reserve. With an exciting and highly educational itinerary ahead of me, I will gain clinical perspective with big cat species in an international setting, and collaborate with esteemed professionals to learn how to better manage cheetahs in captivity and protect their population at large.

Veterinary care is essential in maintaining the health of cheetahs, while education of the global community is necessary to promote conservation efforts. In addition to my cheetah research this summer, I will be participating in AfriCat’s outreach initiatives by assisting with their Environmental Education Program. Working with local Namibian schoolchildren, we will be providing interactive lessons and activities to teach the young generation about carnivore conservation and the agro-ecosystem.

I look forward to embracing the new experiences and challenges that will accompany field research with cheetahs in Namibia this summer. Through my endeavors to improve the welfare of cheetahs and their conservation status, I am excited to dedicate my summer to impacting the lives of others as well as fulfilling my own.

Six speakers discuss different aspects of conservation medicine at the first annual Wildlife Health Day

Dr. Elizabeth Buckles discussing the histopathology of white-nose syndrome, a fungal disease affecting North American bats.

Zack Dvornicky-Raymond DVM (’19)

On Saturday, six speakers shared their experiences in conservation, wildlife, and One Health. The topics were wide-ranging, covering conservation of endangered species, zoo animal nutrition, plastic waste, and honeybee health. For every topic, the speakers highlighted the importance of wildlife health and the role of the veterinarian.

Zack Dvornicky-Raymond (’19), kicked off Wildlife Health Day with a talk that drew from both his personal experience and his knowledge of the conservation field. Zack first described his Expanding Horizons experience in Namibia where he used his veterinary skills to help the Cheetah Conservation Fund with their guard dog breeding program. He then discussed Assisted Reproductive Technologies (ARTs) and their use in breeding endangered species, drawing from his experience studying canine reproduction at the Travis Lab. Zack also drew from his experience at the Smithsonian, where he investigated better ways to transport sperm for the endangered Przewalski’s horse, information critical for preserving the genetic diversity of the species. Zack then discussed the role of contraception-based wildlife management, before finishing off with a reflection about the impact of human population growth on the state of the natural environment.

Dr. Sara Childs-Sanford discussed the unique challenges of managing nutrition in captive wildlife. Many of the nutritional problems that zoo animals face stem from our lack of knowledge of the specific nutritional requirements for these understudied species. Dr. Childs-Sanford did leave the audience with some solutions, citing successful attempts in nutrition research: improving the reproductive success of maned wolves and helping pangolins survive in captivity.

Mariah Beck (’20)

Drawing on her research and coursework, Mariah Beck (’20) shifted the focus to environmental health with her talk on our use and waste of plastic, and its effect on ocean life. She cited three main ways that plastic waste harms marine animals: entanglement, ingestion, and toxicity. Not only do plastics harm iconic species like whales and turtles, but their toxicity also harms animals like mussels which provide important ecosystem services. Mariah called on veterinarians to advocate for reducing the amount of plastic waste in the ocean and pitched ideas to help achieve this goal.

Dr. Elizabeth Buckles dove into a case study on white-nose syndrome in bats, drawing from her own experience as a veterinary pathologist who helped identify the cause of the outbreak. This inspired several principles for working with understudied species including “know your species,” “reach out to experts,” and “be creative.” Dr. Buckles finished with several wildlife pathology anecdotes, including one about how the CDC ignored warnings from veterinarians about the arrival of West Nile Virus to the United States. These examples illustrated the need for veterinarians to speak up to protect both human and wildlife health.

The conversation moved to honeybee health when Dr. Robin Radcliffe gave a lecture on colony collapse and the light that wild honeybee colonies can shed on it. Curiously, wild honeybee populations have not suffered from all of the problems that face captive bee colonies. For instance, as Dr. Radcliffe explained, wild honeybees have developed behavioral immunity to the Varroa mite which has devastated captive bee populations. His main  message was that there is a need for greater monitoring of colony health by the veterinary community, something the Cornell College of Veterinary Medicine is facilitating by adding a new distribution course on apiary medicine.

Dr. Sharon Deem speaks at Wildlife Health Day 2018.

Dr. Sharon Deem, wildlife veterinarian for the St. Louis Zoo, finished off the day as the keynote speaker. She rehashed many of the issues brought up by other speakers, while also sharing her perspective on the most important issues in wildlife health. Dr. Deem emphasized One Health, drawing on her research on diseases of camels being used as livestock in Kenya.  She left the audience with advice for future wildlife veterinarians.

Wildlife Health day drew dozens of vet students and faculty, giving members of the Cornell Veterinary community a chance to learn about the opportunities and challenges within the field. These types of events aim to increase levels of awareness and emphasize the importance of veterinarians in conservation and One Health.

Breeding Livestock Guard Dogs and Protecting Cheetahs

My name is Zachary Dvornicky-Raymond, and I’m a member of the Cornell University College of Veterinary Medicine’s class of 2019. As far back as I can remember, I have dreamed of working with wildlife and having a lasting impact on global conservation. The Expanding Horizons program gave me the opportunity to take my first steps toward fulfilling my dream.

I spent the summer of 2016 at the Cheetah Conservation Fund (CCF), based outside of Otjiwarongo, Namibia. The CCF was founded by Dr. Laurie Marker in 1990, with the goal of saving the cheetah from extinction through a multifaceted approach to conservation. Habitat loss and fragmentation, and declining prey availability, have resulted in cheetahs predating on livestock and entering into human-wildlife conflict situations with farmers.

The Livestock Guard Dog Project is a unique approach to human-wildlife conflict mitigation, whereby Anatolian Shepherd/Kangal dogs are bred and raised amongst livestock, and then placed at farms throughout Namibia. Through their presence and loud bark, the dogs reduce livestock predation by 80-100% in the herds where they are placed. By reducing predation, the program provides security for the farmer’s livestock herd, and reduces retaliatory killings, mostly against cheetahs.

The Livestock Guard Dog Project has been extremely successful in the past, not only in reducing cheetah mortalities, but also in improving the outlook that local communities have toward cheetahs. Since 1994, over 450 dogs have been placed in farms throughout Namibia. However, the program has also encountered reproductive setbacks within the breeding colony. In short, they experienced multiple failed breeding attempts and whelping complications. The goal of my project was to try to identify and solve those problems using what I learned through the DVM curriculum, combined with knowledge I had gained from working on canine reproductive research at Cornell.

Throughout my time in Namibia, I gained first-hand experience working in conservation. I worked and talked with local farmers to learn about their lives, experiences, and concerns; I observed, assisted with, and conducted veterinary procedures on numerous wild and domestic species; I learned about aspects of the veterinary medical profession that I had no idea even existed. And, as part of a team, I produced results that have truly made a difference. Our work solved many of the problems that the LSGD program was encountering and, as a testament to our success, multiple litters have been born since I left.  We truly made a difference that summer, and the effects of my work will far outlast my time at CCF – and that fact alone makes my experience worthwhile. I came in expecting the problem to be solely due to medical anomalies, but what I quickly realized is that we also had to make management and communication adjustments to truly benefit the program. We not only pinpointed the root of many of the medical problems that they were encountering, but through a collaborative effort, we created new management protocols for the breeding colony.

Looking back on that summer, specifically to the very beginning, I realize that I had high aspirations for the outcome of my trip. I am beyond pleased to write that my expectations were far exceeded. Seeing the research center and meeting the staff for the first time was nothing short of surreal. Although I had seen plenty of photos and read extensively about the work being done there, it paled in comparison to the reality. I quickly came to realize that the staff and veterinarians working with the Livestock Guard Dog Project were as excited for my project as I was, and that we had so much to teach each other. So we did.

Much of my time in the first few weeks was spent learning the ins and outs of operations at CCF. I worked extensively with the veterinarians on all of the animals at the center, from big cats to guard dogs, from goat kids to horses. The Livestock Guard Dog manager and I spent hours going through the history of the program, the setbacks they had encountered, the improvements that have been made to the program, and what we needed to accomplish together. It was a big task, but we were up to the challenge.

One of my favorite lessons from this experience was learning the role of a veterinarian within a team. All of the care provided to the animals, whether goats, dogs, or cheetahs, required collaboration between husbandry staff, veterinarians, and administration. The veterinarians relied on the husbandry staff for surveillance, monitoring, and history. After all, the husbandry staff knew these animals more than anyone else at the center. I learned quickly how important it was to listen to the team, given how diverse the areas of expertise were within the group.

When I visited local farms, where human-wildlife conflict was a reality, my primary role was again to listen and learn. By doing so, I gained a much better idea of how to approach these issues than I would have if I had just rushed in and tried to fix them alone. Even then, it took creativity and persistence to find answers and every person played a part, which was especially important when theory did not match practice.

This is perhaps the most important thing that I took from my experience: that any initiative in conservation, community outreach, conflict-remediation, or whatever the task may be, requires full buy-in, understanding, and effort from every person involved. A program achieves the greatest success only through the combined expertise of the farmers, the researchers/staff, the management, and the veterinarians. After all, conservation is just as much about improving human lives as it is about protecting and preserving the lives of animals.

My experience in Namibia came at the perfect time in my life, and was without a doubt the most personally fulfilling and inspiring journey I have been on. This opportunity solidified my resolve to pursue conservation medicine as a lifelong career. There are many problems that face our world and, although few of them can be easily solved, I believe that change can occur through collaboration and multifaceted approaches aimed at improving the lives of humans and animals together. Thank you to the Expanding Horizons program, to Cornell University, to the Cheetah Conservation Fund, to the Silent Heroes Foundation, and to everyone who supported me in making this trip possible. I look forward to completing veterinary school, and to the long journey that follows thereafter.

The Realities of Infectious Disease Research in the Field

Thanks to funding from Expanding Horizons, this summer I partnered with Conservation Through Public Health (CTPH) to conduct research in Queen Elizabeth National Park (QENP). CTPH is a non-profit non-governmental organization, focused on improving the health of animals and people around protected areas in Africa while also advancing initiatives in wildlife conservation. Put more simply, it addresses the reality that wildlife conservation cannot occur without simultaneous partnership with humans whose livelihoods are closely intertwined with, and often dependent on, the same resources that endangered wild animals need. In my opinion, one of the most interesting problems in wildlife conservation is how to make conservation a priority for everyone. Dr. Gladys Kalema Zikusoka, one of the founders of CTPH and the first wildlife veterinarian for the Uganda Wildlife Authority (UWA), was motivated to address this need. Since it was founded in 2002, CTPH has implemented public health programs in Bwindi Impenetrable National Park, QENP, Mount Elgon, and other protected areas in Uganda. CTPH has worked in communities with significant interaction with wildlife, training Conservation Community Animal Health Workers to assist researchers in sampling animals and to report signs of disease outbreaks to UWA.

Buffalo (red box) grazing in close proximity to cattle.

My objective for this summer was to conduct research on the prevalence of brucellosis and tuberculosis, both zoonotic diseases with the potential to infect humans, in African buffalo and cattle in communities around QENP. Three different villages around QENP were chosen based on disease prevalence of free range cattle and proximity to the national park. In a study published by Dr. Gladys and other researchers in 2005, the prevalence of Mycoplasma bovis and Brucella abortus was 22% and 2%, respectively. The first survey of bovine tuberculosis in QENP in 1960, which was referenced in Dr. Gladys’ study, concluded that the disease had originated in cattle and spread to buffalo. Infected buffalo were only found in areas of the park close to villages with cattle that were positive for tuberculosis. Since this wildlife reservoir has been established, the challenge now is to eradicate the disease in both populations. My research consisted of conducting surveys of pastoralists, and sampling blood from cattle to perform laboratory tests for the infectious diseases. Having worked in research laboratories throughout my undergraduate career, it was easy for me to learn the procedure for the brucellosis serum agglutination test. However, it was much more fulfilling to conduct surveys because I learned so much about common practices in raising cattle outside the United States, perceptions of foreign researchers, and how it is extremely challenging to control all the variables when conducting research in the field.

To conduct surveys, I woke up at 5:30 am to drive to villages before the cattle were led, by herdsmen, into QENP to graze for the day. It was necessary for the cattle to leave so early in order to begin feeding before the heat of the day reached its peak. Our team once drove over five miles into QENP to chase after a specific group of cattle to sample. That journey was a testament to how much energy the cattle had to expend to find food, relative to the poor nutrition they received from the dry, brittle, and overgrazed grass.

Ugandan kob grazing with domestic cattle.

In a moment that made the fatigue from chasing cattle worthwhile, I spotted a buffalo and a few Ugandan Kob mingling with the cattle. Just as there are no boundaries between wildlife and livestock, there are no boundaries between livestock and humans in the village. If a buffalo infected with Brucella abortus were to have an abortion in QENP, and a grazing cow ingested the placenta or vaginal discharges, the infection could be passed to the domestic cattle. A human that drank raw milk from an infected cattle could then become infected, as well. The challenge of developing boundaries of QENP around and within pre-existing communities without allocating grazing land is there there are insufficient natural resources. Cattle cannot rely solely on grazing within the village. While the government punishes people for grazing cattle in QENP, it does not provide alternative methods to feed cattle that are affordable. Nutrition is essential because cattle or buffalo that do not receive enough nutrition from grazing have a less robust immune system to respond to and eliminate infection.

Before beginning my research, I traveled to each village and met each village leader. The village leader is an elected individual who holds the most political influence within the village. Dr. Kellen, a Ugandan wildlife veterinarian, translated information about CTPH, the research project, and what we would need. After receiving support from all three village leaders, we traveled from house to house with a local to facilitate introductions.

Despite the support of the village leaders, I immediately ran into opposition from community members. At the first house, before we had finished communicating the premise of our research, a villager interjected to say that many researchers in the past had come, collected samples from his cattle and asked him questions, but none had distributed any results or provided compensation. This theme was repeated throughout houses in all three villages. There were also accounts of researchers injecting vaccines around the tail-head of cattle and causing necrosis of the entire tail. Anyone who assumed that we were researchers from Ugandan Wildlife Authority refused to talk to us or allow us to sample their cattle. It was concerning to see that the governmental body responsible for protecting wildlife did not seem to have the support of the people. UWA charges entrance fees for almost all the protected areas in Uganda, for many safari and animal tracking opportunities, and for permits to conduct research on animals in Uganda. However, only a small percentage of this income is given to the communities around the national parks, provided that the people have demonstrated certain initiatives toward advancing wildlife conservation.

Once we explained that we were with Conservation Through Public Health, an independently-run, Ugandan-based organization with a history of disseminating results back to communities, the locals became much more receptive to participating in our research. I surveyed 51 pastoralists and sampled 97 cattle. Through the surveys,  I was able to analyze the risk factors, such as handling of newborn calves, slaughtering of cattle, and type of milk consumed, that could lead people to brucellosis infection. I learned that the local name for brucellosis was omusuja gwente, which translates to malaria of cows. Wildlife conservation will only succeed with teamwork from multiple different sectors, and without the pastoralists reporting infectious disease outbreaks to veterinarians and UWA, a significant player in disease detection would be lost.

As a result of the surveys, I identified certain practices that places people at risk for brucellosis transmitted from cattle, including close contact with newborn calves, and leaving aborted calves in the fields or feeding them to other animals. Thirty-nine percent of respondents had observed at least 3 clinical signs of brucellosis in their cattle (abortion, stillbirth, weak calf, retained placenta, orchitis/epididymitis). From the serum agglutination test for brucellosis, I determined that there was 0% prevalence of B. abortus in the cattle that were sampled. While this is positive preliminary data, more in depth investigation should and will be conducted to whether this is the true prevalence.

As a pre-veterinary student, a professor encouraged me to pursue both wildlife and livestock interests because of the need for veterinarians in developing nations. It was a concept that was very new to me then, but resonates with me now. My initial plans for darting and sampling buffalo for my project were canceled due to numerous bureaucratic issues, but I learned that wildlife veterinary medicine isn’t usually chasing outbreaks or performing surgeries. I have a lot more to learn and explore, but I am very glad to have journeyed to Uganda to get a glimpse of what is possible in the years to come.

Veterinary students may get involved in research through a formal program, or by directly contacting a faculty member or clinician.  We encourage students interested in research to read more about the work of different faculty members all across the veterinary college and at affiliated locations, and to contact those researchers directly to get involved.  We do not currently have a central location to look up clinical research opportunities.

Doctor of Veterinary Medicine (DVM) Curriculum

The DVM Curriculum incorporates Problem-Based Learning (PBL) and hands-on labs to immerse students in active learning, problem-solving, and case-based learning from their very first day.  Read more about the overall DVM curriculum here.

For students interested in Zoo and Wildlife Medicine, a variety of elective courses can be taken during Distribution periods during the academic year, as well as field courses during breaks.  Funding is available for international experiences completed over the summer through Expanding Horizons and Engaged Cornell.

Elective Distribution Courses
Conservation Medicine (VTMED 6735)
Veterinary Medicine in Developing Nations (VTMED 6723)
One Health: Conservation with Communities (VTMED 6743)
Clinical Management of Native Wildlife (VTMED 6728)
Veterinary Aspects of Captive Wildlife Management (VTMED 6527)
Fish Health Management (VTMED 6432)
Avian Biomedicine and Diseases (VTMED 6565)
Clinical Aspects of Non-Traditional Species (VTMED 6569)

 

Field courses
Field Techniques of International Wildlife Management (VTMED 6737) – this course allows to travel to Belize to work with the Zoological Medicine faculty at the Belize Zoo. Students have the opportunity to learn about the management of captive wildlife as well as assist with everything from physical exams to dental procedures on many amazing and endangered species. The Belize Zoo is a wonderful organization that has a strong conservation mission.

One Health: Conservation with Communities (VTMED 6743) is offered as a distribution class every spring semester. The class is cross-listed between the veterinary school and the undergraduate Department of Natural Resources. Students in the class can apply for a summer internship program that will allow for them to gain hands-on experience in the field of international species conservation! Four DVM and four undergraduate students from the class are selected for internships. One DVM student and one undergraduate student are paired together to intern at each of the four field sites. Two field sites are in Indonesia, where students partner with organizations like WWF and ALeRT on rhino conservation, while two field sites are in Africa (Uganda and Republic of Congo) where students work on chimpanzee conservation through the Jane Goodall Institute.

AQUAVET is a program in Aquatic Veterinary Medicine offered each summer by Cornell and held at Roger Williams University in Bristol, Rhode Island, where students gain classroom and laboratory hands-on experience with aquatic species. AQUAVET I is a 4-week course that serves as an Introduction to Aquatic Veterinary Medicine.  Students may choose to go on to AQUAVET II, a 2-week course on the Comparative Pathology of Aquatic Animals, and AQUAVET III, a 5-week course on the Clinical Aspects of Captive Aquatic Animal Medicine.  AQUAVET also holds a summer fellowship research program at the Fish Diagnostics Laboratory at Cornell, where students spend 8 weeks investigating a selected fish viral disease.

FARVets International is a 501c3 non-profit organization run by Cornell professor Dr. Paul Maza DVM PhD.  FARVets partners with grassroots animal welfare groups in Mexico, Belize, Costa Rica, Grenada, Nicaragua, and Bulgaria, and brings veterinary students to participate in spay and neuter clinics during school breaks.  FARVets aims to address overpopulation while contributing to education on preventative medicine, pet health, wellness, and the human-animal bond, while giving veterinary students meaningful international experience.

 

During their final year, students have the option of choosing a professional “track”, which helps to guide their clinical year rotations.  The tracks are as follows:

  • Small Animal
  • Large Animal
  • Mixed Animal
  • Zoo/Wildlife
  • Small Animal & Exotics

Students who complete the Zoo/Wildlife/Exotics elective rotation spend their time at the Exotic Pet Service at Cornell University Hospital for Animals, the Rosamond Gifford Zoo, and the Janet L. Swanson Wildlife Health Center.

Student Organizations

List of Student Organizations with Zoo/Wildlife/Exotics opportunities:

Zoo and Wildlife Society (ZAWS)

The Zoo and Wildlife Society (ZAWS) strives to provide educational opportunities in zoological, exotic, and wildlife medicine for veterinary students and the greater Cornell community. ZAWS aims to promote programs in research, husbandry, education, and conservation. We present lectures, wet labs, and field trips to students throughout the year. Student representatives in the fields of reptile and amphibian medicine, avian medicine, aquatic animal medicine, exotic mammal medicine, and wildlife medicine help to promote the diverse interests within our organization. In addition, we proudly host the Special Species Symposium biennially, which brings veterinary students and professionals together in a three-day event that features an array of expert speakers and unique activities in fields outside of the standard veterinary curriculum.  For questions, email zawscornell@gmail.com.

Wildlife Disease Association (WDA)

The Cornell chapter of the Wildlife Disease Association is run as a subset of the Zoo and Wildlife Society.  WDA connects students, faculty, and researchers interested in free-ranging wildlife.

Veterinarians Interested in Developing Areas (VIDA)

Veterinarians Interested in Developing aims to connect internationally-minded veterinary students with opportunities to study or work abroad and assists in organizing Expanding Horizons presentations.

Tropical Biology and Conservation Graduate Student Association (TBC-GSA)

The Tropical Biology and Conservation Graduate Student Association is an international organization which promotes wildlife biology and conservation by facilitating interdisciplinary collaboration among scientists. Faced with complex and multifaceted global issues, our scientific approach must integrate knowledge across seemingly distant areas of study. Our biweekly meetings vary from student and faculty research presentations to topic driven discussion. Topics range from tropical biology and ecology, to anthropology, One Health, veterinary medicine, indigenous studies, sustainability and environmental studies and much more. The TBC-GSA’s goal is to bridge the many disciplines that work in conservation and biology at Cornell to facilitate multidisciplinary approaches towards projects and research. For questions, contact tbc-gsa-l@cornell.edu.

Veterinary One Health Association (VOHA)

The Veterinary One Health Association aims to provide graduate and veterinary students with programming and lectures on One Health and public health topics, and to provide networking opportunities for students interested in veterinary public health. VOHA organized the annual Veterinary One Health Symposium in Ithaca, NY, held in the fall at the vet school, and host the George C. Poppensiek Visiting Professor of Global Health lecture series. The Cornell OIE Junior Ambassador sits on our board, and thus, VOHA also hosts OIE campaign events such as lectures/labs related to African Swine Fever, antimicrobial resistance, etc.
