Evaluation of hematological profile, biochemical and peripheral blood smear with a view to the health profile in primates of the Cebus genre maintained in captivity

Abstract

Non-human primates serve as a model for studies on the dynamics of transmission routes and natural history of diseases shared between humans and animals. The captive environment is conducive the dissemination of zoonotic diseases. Many of these animals do not present clinical symptomatology, even when infected, which characterize them as an important source of infection for domestic animals and man. The objective of this study was to evaluate the sanity of non-human primates kept in captivity through hematological and biochemical analysis as well as peripheral blood smear, aiming to investigate the presence of zoonotic pathogens, serving as a model for future studies on the dynamics of routes of transmission of diseases shared between humans and animals. Were collected samples of blood from 15 nail monkeys (Cebus sp.), adults, clinically healthy and belonging to Park Zoobotanic of Teresina. Were stained smear sanguine blades and obtained the haematological and biochemical profiles of each animal. The data analysis was based on basic statistics. Did not observed any haemoparasite present in peripheral blood. All animals were anemic, 46,7% thrombopenics and 87% of the animals showed some type of pathological process of chronic evolution, due to the high rate of monocytes found. All animals showed high rates of alkaline phosphatase, and transaminases AST and ALT, indicating injury of the hepatic parenchyma. New studies should be conducted to better elucidate of results, seeing that biochemical physiological data primate of the genus Cebus are scarce in literature.
