Hematology and blood biochemistry in wild hybrid marmosets from the Atlantic Forest, Brazil

Abstract

This paper aims to describe the hematological and biochemical values of wild hybrid marmoset (Callithrix penicillata and C. geoffroyi) found in a forest zone of Southeastern Brazil. The marmosets were anaesthetized using ketamine and xylazine hydrochloride. Blood samples (0.5-1mL) were collected through the venipuncture of the femoral vein. Hematological and biochemical analyses were performed using automated counters and biochemical kits. The comparison for sex (adult males vs. adult females) and age class (juvenile vs. adult) physiological data and weight were analyzed through Student's t-test for independent samples. Significant differences between sex were observed in erythrocytes (P<0.01) and hemoglobin (P<0.05). The present study provides essential baseline information on the normal blood values of wild hybrid marmosets, the data of which are not readily accessible from the existing body of scientific literature on nonhuman primates.
