<p>Hematological and serum biochemistry evaluation in howler monkeys (Alouatta caraya) and capuchin monkeys (Sapajus apella): A comparative study</p>

Corpo do texto

<p>Assessment of blood parameters in captive non-human primates (NHPs) is crucial to monitor their health and ensure that their environment meets their physiological requirements. We performed blood counts, serum biochemistry and parasitological tests on 20 [howler monkeys] and 21 [capuchin monkeys]. The aim was to evaluate the health status of primates kept under human care at CENP. In both species, more than 50% of individuals had at least one parasite. There was a negative effect of age on red blood cells (RBC), white blood cells, platelets, total protein, globulin and alkaline phosphatase, and a positive effect on A:G ratio, gamma-glutamyl transferase and mean platelet volume (MPV). [Capuchin monkeys] had the highest values of platelets and alanine aminotransferase (ALT) and [howler monkeys] had the highest values of MPV, aspartate aminotransferase, ALT, amylase, glucose, bilirubin and triglycerides. Therefore, the negative effect of age was observed in both species. We observed an interaction between species and sex in red blood cells, Htc, mean corpuscular hemoglobin concentration and cholesterol. Interspecies differences found in blood parameters may reflect differences in physiological adaptations associated with ecological and morphological traits and are clinically relevant for assessing animal health and the suitability of breeding programs.</p>
