Abstract
BACKGROUND Anthropogenic disturbances are the main threats to nonhuman primates conservation, and infectious diseases may also play a key role in primate population decline. This study aimed to determine the main causes of death in neotropical primates. METHODS A retrospective study of post-mortem examinations was conducted on 146 neotropical primates between January 2000 and December 2018. RESULTS Conclusive diagnoses were obtained in 68.5% of the cases, of which 59 corresponded to non-infectious causes and 41 to infectious diseases. Trauma was the main cause of death (54/100), with anthropogenic stressors caused by blunt force trauma injuries (collision with vehicles) and puncture wound injuries associated with interspecific aggression (dog predation) were the most common factors. Other causes of death included bacterial diseases (27%), followed by parasitic diseases (12%), neoplasms (2%), and viral diseases (2%). CONCLUSIONS Free-ranging primates were mostly affected by non-infectious causes, while captive primates were by infectious conditions.

Abstract
As a result of many factors, including climate change, unrestricted population growth, widespread deforestation and intensive agriculture, a new pattern of diseases in humans is emerging. With increasing encroachment by human societies into wild domains, the interfaces between human and animal ecosystems are gradually eroding. Such changes have led to zoonoses, vector‐borne diseases, infectious diseases and, most importantly, the emergence of antimicrobial‐resistant microbial strains as challenges for human health. Now would seem to be an opportune time to revisit old concepts of health and redefine some of these in the light of emerging challenges. The One Health concept addresses some of the demands of modern medical education by providing a holistic approach to explaining diseases that result from a complex set of interactions between humans, environment and animals, rather than just an amalgamation of isolated signs and symptoms. An added advantage is that the scope of One Health concepts has now expanded to include genetic diseases due to advancements in omics technology. Inspired by such ideas, a symposium was organised as part of the 19th International Federation of Associations of Anatomists (IFAA) Congress (August 2019) to investigate the scope of One Health concepts and comparative anatomy in contemporary medical education. Speakers with expertise in both human and veterinary anatomy participated in the symposium and provided examples where these two disciplines, which have so far evolved largely independent of each other, can collaborate for mutual benefit. Finally, the speakers identified some key concepts of One Health that should be prioritised and discussed the diverse opportunities available to integrate these priorities into a broader perspective that would attempt to explain and manage diseases within the scopes of human and veterinary medicine.

Abstract
Due to the global burden of dengue disease, a vaccine is urgently needed. One of the key points in vaccine development is the development of a robust and reliable animal model of dengue virus infection. Characteristics including the ability to sustain viral replication, demonstration of clinical signs, and immune response that resemble those of human dengue virus infection are vital in animal models. Preclinical studies in vaccine development usually include parameters such as safety evaluation, induction of viremia and antigenemia, immunogenicity, and vaccine effectiveness. Although mice have been used as a model, non-human primates have an advantage over mice because of their relative similarity to humans in their genetic composition and immune responses. This review compares the viremia kinetics and antibody responses of cynomolgus macaques (Macaca fasicularis), common marmosets (Callithrix jacchus), and tamarins (Saguinus midas and Saguinus labitus) and summarize the perspectives and the usefulness along with challenges in dengue vaccine development.

Abstract
Cancer is a disease of multicellularity; it originates when cells become dysregulated due to mutations and grow out of control, invading other tissues and provoking discomfort, disability, and eventually death. Human life expectancy has greatly increased in the last two centuries, and consequently so has the incidence of cancer. However, how cancer patterns in humans compare to those of other species remains largely unknown. In this review, we search for clues about cancer and its evolutionary underpinnings across the tree of life. We discuss data from a wide range of species, drawing comparisons with humans when adequate, and interpret our findings from an evolutionary perspective. We conclude that certain cancers are uniquely common in humans, such as lung, prostate, and testicular cancer; while others are common across many species. Lymphomas appear in almost every animal analysed, including in young animals, which may be related to pathogens imposing selection on the immune system. Cancers unique to humans may be due to our modern environment or may be evolutionary accidents: random events in the evolution of our species. Finally, we find that cancer‐resistant animals such as whales and mole‐rats have evolved cellular mechanisms that help them avoid neoplasia, and we argue that there are multiple natural routes to cancer resistance.

Abstract
Much has been written about hepatic metastasis and animal models abound. In terms of the human experience, progress in treating this final common pathway, a terminal event of many human malignancies has been relatively slow. The current thinking is that primary prevention is best served by early detection of cancer and eradication of early stage cancers by screening. Some cancers spread early in their course and the role of screening may be limited. Until relatively recently there has not been a pathfinder model that makes the evasion of this unfortunate event a reality. This review discusses such an animal model and attempts to relate it to human disease in terms of intervention. Concrete proposals are also offered on how scientists may be able to intervene to prevent this deadly progression of the cancer process.

Abstract
We histopathologically and immunohistochemically investigated a case of malignant
lymphoma that spontaneously developed in a male common marmoset at two years of age.
Beginning at two years four months of age, the animal had an enlargement of the
submandibular and inguinal lymph nodes, small subcutaneous nodules near the right breast
and an approximately fivefold increase in peripheral lymphocyte count compared with the
previous examination value. The postmortem findings at two years eight months of age
showed lymphadenopathy with enlargement of the thymus and spleen. Small- to
intermediate-sized neoplastic lymphocytes had diffusely proliferated in the enlarged
nodes. The neoplastic cells were pleomorphic and had irregularly shaped nuclei. The
nuclear chromatin staining revealed hyperchromatism in the small-sized cells, and the
intermediate-sized cells exhibited vesicular staining. An immunohistochemical examination
indicated that the neoplastic lymphocytes were positive for CD3 and negative for CD20,
thus suggesting that they had originated from T cells. In addition, the proliferation of
high endothelial venules and reactive epithelioid histiocytes was observed. Scattered
tingible body-laden macrophages were infrequently detected. Neoplastic lymphocytes were
also observed in the thymus, spleen, heart, lungs, liver, kidneys, adrenal glands and
femoral and sternal bone marrow. This malignant lymphoma in a young male common marmoset
was considered to fit the category of “peripheral T-cell lymphoma, not otherwise specified
(PTCL-NOS)” according to the new WHO system of classification.

Abstract
BACKGROUND Marmosets and tamarins are increasingly used in research, but their pathology remains poorly defined compared with Old World primates. METHODS Necropsy records of 129 marmosets and 52 tamarins were reviewed; none was used experimentally. RESULTS The most common marmoset lesions were dehydration, emaciation, nephritis, colitis, and inanition. The most common tamarin lesions were dehydration, ascites, emaciation, and congestive heart failure. Colitis and heart disease were the most common cause of death in marmosets and tamarins, respectively. Immature marmoset and tamarin deaths often occurred within the first month of life. Immature marmosets usually died from inanition, stillbirth, and colitis; immature tamarins from atelectasis, stillbirth, heart failure, and colitis. Lymphoma was the most common neoplasm for both marmosets and tamarins. CONCLUSION The findings were similar to prior reports with differences in frequency and severity. We report the first case of endometriosis in a marmoset.

Abstract
Neoplastic diseases in prosimians have been sporadically reported in the literature. To provide a comprehensive review of prosimian neoplasia, a retrospective evaluation of neoplasia in a large captive prosimian colony and an extensive literature review were performed. Primates that belong to the Order Primata, Suborder Prosimii with histologic evidence of neoplasia were included. One hundred twenty-three cases of spontaneous neoplasia were identified in 101 prosimians from the Duke Lemur Center, and 124 cases were reported in 116 prosimians in the literature. Overall, this review compiled a total of 247 neoplasms in 217 prosimians. Of the 217 affected animals, 88 of 217 were males (41%), 100 of 217 were females (46%), and sex was not reported in 29 of 217 (13%). Ages ranged from 2 days to 36 years. Prosimian families represented were Lemuridae (80/217 [37%]), Cheirogaleidae (61/217 [28%]), Galagidae (44/217 [20%]), Lorisidae (28/217 [13%]), and Indriidae (4/217 [2%]). The most commonly affected species were the gray mouse lemur (Microcebus murinus) (28/217 [13%]), thick-tailed greater bush baby (Otolemur crassicaudatus) (23/217 [11%]), and black lemur (Eulemur macaco) (19/217 [9%]). Organ systems affected, in order of descending occurrence, were digestive (75/247 [30%]), reproductive (40/247 [16%]), hematopoietic (34/247 [14%]), integumentary (28/247 [11%]), endocrine (26/247 [11%]), and urinary (17/247 [7%]). The respiratory, nervous, musculoskeletal, and cardiovascular systems were infrequently affected. The most common neoplasms were hepatocellular (32/247 [13%]), lymphoma and/or leukemia (29/247 [12%]), biliary (15/247 [6%]), and mammary neoplasms (12/247 [5%]). This article should serve as a valuable reference for the types and relative frequencies of neoplasms that occur in prosimian species.

Abstract
A spontaneous T-cell-rich B-cell lymphoma (TCRBCL) occurred as a subcutaneous mass in the buccal region and enlarged submandibular lymph node in a 6-year-old female cynomolgus monkey (Macaca fascicularis). The constituent cells were examined by histology, immunohistochemistry and the double labeled-immunofluorescence method (dl-IF). Further, in situ hybridization (ISH) was employed to detect the gene expression of Epstein Barr virus (EBV). Histologically, the mass was comprised mainly of neoplastic large lymphoid cells and reactive small mononuclear cells. Immunohistochemically, the neoplastic large lymphoid cells were positive for CD20, CD79 alpha, MHC class II, and either IgG, IgM, or IgA. Polyclonal Ig production by the neoplastic large lymphoid cells was demonstrated by dl-IF, although IgG-positive ones predominated in number. On the other hand, most of the small mononuclear cells were positive for CD3 and were regarded as reactive T lymphocytes, while the remaining cells appeared to be histocytes or reactive B-cells. Transcripts of EBV gene were not demonstrated in these neoplastic or reactive cells by ISH. This is the first reported case of spontaneous TCRBCL in the cynomolgus monkey.
