“…Hemosiderosis is a common incidental finding among New World Primates kept under human care, being reported in genus like Callithrix, Brachyteles , Lagothrix , and Aotus 30,31 . Its occurrence is related to high levels of iron in the diet, increased endogenous corticosteroids, or chronic inflammation and, although it was present in many cases, it was not associated with the cause of death 30–32 …”

“…30,31 Its occurrence is related to high levels of iron in the diet, increased endogenous corticosteroids, or chronic inflammation and, although it was present in many cases, it was not associated with the cause of death. [30][31][32] Causes of death referent to circulatory system were attributed from metastatic splenic hemangiosarcoma with spleen rupture in an adult male and neonatal triad in a newborn female. Neonatal triad is a serious condition composed by hypothermia, dehydration and hypoglycemia which newborns are susceptible during the first week of life.…”

BackgroundThe Vieira's titi monkey (Plecturocebus vieirai) was recently described and characterized as endemic to Brazil. According to the IUCN red list, this species is classified as critically endangered (CR). At the date of the publication of this manuscript, there are no published data on the health aspects of this species.MethodsFor this study, the necropsy, and histopathological data of the mortality of P. vieirai at Sorocaba Zoo (São Paulo, Brazil) were collected and analyzed.ResultsCauses of death diagnosed included disorders of the urinary, gastrointestinal, immune, and circulatory systems.ConclusionsThis study provides information regarding the pathological conditions of P. vieirai and points to urinary and gastrointestinal diseases as the main causes of death in this species at Sorocaba Zoo. These results can help veterinarians who have this species under their care diagnose and deal with it more quickly, increasing the probability of survival.

“…The authors, however, believes that the negative results may be due to a low bacteremia, once the animals from the study were all asymptomatic. Also, bartonellosis was investigated by PCR, Warthin-Starling stain and IHC in two cases of hepatic peliosis in captive owl monkeys (A. infulatus), but no evidence of bacteria was found (204).…”

Neotropical primates are represented by more than 200 species and subspecies distributed in five families. Considering that some of these species are considered endangered, disease investigation in these populations is critical for conservation strategies. Therefore, an increasing number of studies and publications on this topic became available in the past few years. This review deals with infectious diseases of neotropical primates, with focus on free-ranging animals, including those caused by bacterial, viral, protozoal, metazoan, or mycotic infectious organisms, with particular emphasis on gross and microscopic lesions associated with these diseases. In addition, a few relevant unpublished cases of infection by Staphylococcus spp., Streptococcus spp., E. coli and Pseudomonas spp. were included in this review.

The owl monkeys (Aotus sp.) are considered excellent experimental models for biomedical research, in particular for studies on vision 1 and malaria. 2 For such studies, the use of animals with normal liver function is crucial to ensure an adequate experimental protocol. The liver is involved in several physiological functions, including biosynthesis, detoxification, digestion, and immunity, being the major elimination pathway for several drugs. 3 Hepatic diseases may impair these functions and result in accumulation of toxins in the body, 4 which can affect experimental treatments. Monitoring hepatic function is therefore essential to avoid the impact of pre-existing liver conditions in the outcome of experiments.Liver conditions such as fatty liver disease, spontaneous gallstone formation, and focal nodular hyperplasia have been reported in Aotus trivirgatus, 5 Papio sp, 6 Saimiri sciureus, 7 Macaca fascicularis, 8
