Biochemical parameters, C-reactive protein, and proteinogram of Sapajus libidinosus kept in captivity

Abstract

Sapajus libidinosus is a New World primate belonging to the Cebidae family that lives in the caatinga and cerrado, which are known Brazilian biomes. It is currently classified as near threatened, almost endangered, by the main animal protection organizations. Knowledge of biochemistry, the C-reactive protein, and the proteinogram are important for the preservation of this species. Our study established reference intervals for several biochemical variables and the proteinogram. For this purpose, blood samples were collected from 50 S. libidinosus monkeys (25 males and 25 females) kept in captivity at the Brazilian state of Paraíba. Descriptive analysis and reference intervals were estimated following the guidelines of the American Society of Veterinary Clinical Pathology, using the Reference Value Advisor 2.1 software. In the overall population (n=50), significant differences (P < 0.05) were noted for creatinine and total proteins when considering the age factor (higher in adults), as well as for albumin and indirect bilirubin (higher in juveniles). Sex-associated differences (females versus males, P < 0.05) were reported for serum urea and creatinine (higher in males), as well as for albumin and Beta-Globulins (higher in females). In conclusion, to the authors’ best knowledge, the present results are innovative and can be used as reference intervals for assessing the animals’ health status. Moreover, it is also pioneer in determining the C-reactive protein in this species. It is important to emphasize that gender and age categories can have an influence and should be considered when interpreting the tests results.

“…Supporting this concept, the F6 and F9 with ECC 1 (emaciated) had lower concentrations of albumin. The albumin levels of the capuchin monkeys analyzed were similar to those found in a previous study for captive Sapajus libidinosus , with an average of 3.2 g/dL 28 …”
