Postmortem exams in nonhuman primates during yellow fever epizootic in Sorocaba Metropolitan Region (RMS), SP, Brazil

Abstract

Main mortality causes of neotropical primates are trauma and viral, bacterial and parasitic diseases. In all cases of animal death necropsy, histopathology, and complementary exams are essential to determine the cause of death. Between May 2017 and May 2018, 59 cases of death of non-human primates were registered during the Yellow Fever outbreak in the region of Sorocaba, São Paulo, Brazil. Five species of the genera Callithrix, Alouatta and Sapajus were identified. Wildlife and captivity animals were represented. All biological materials collected during necropsies were submitted to Instituto Adolf Lutz (in São Paulo, Brazil) to be tested for the Yellow Fever virus. Documented causes of death included Yellow Fever, unspecified trauma, interspecies and intraspecies aggression, firearm-induced trauma, pneumonia, and carbamate toxicosis.
