Biochemical Parameters of Two Sympatric Primates in the Atlantic Forest: The Native Callithrix jacchus and the Exotic...

We analyzed blood biochemical parameters in two groups, Callithrix jacchus (C. jacchus) and Saimiri sciureus (S. sciureus), in sympatry in the Atlantic Forest, Northeastern Brazil. The procedures included precapture and capture for health assessment and blood collection between January and September 2019. The parameters analyzed were triglycerides, total cholesterol (TC), VLDL, LDL, HDL, total protein (TP), albumin, globulins, urea, and creatinine (this only in S. sciureus). Females in C. jacchus group presented high means of TC (195.4 ± 34.8 mg/dL), LDL (76.6 ± 57.6 mg/dL), and HDL (142.7 ± 86.4 mg/dL) in relation to other cited literature values, and there were significant differences in TC, protein profile, and urea when comparing ages. Females in the S. sciureus group had higher means of TC (463.9 ± 101.8 mg/dL), HDL (137.3 ± 65.5 mg/dL), and albumin (4.95 ± 0.8 g/dL) and juveniles had higher means of HDL (116.3 ± 67.8 mg/dL), TP (15.62 ± 3.3 g/dL), albumin (4.62 ± 0.7 g/dL), and globulin (10.99 ± 3.6 g/dL). The animals were clinically healthy and the data presented can help in understanding the clinical health conditions of these species, as well as provide subsidies in the development of conservation strategies.
