Abstract
ABSTRACT: Bearded Capuchin or Black-striped Capuchin monkeys (Sapajus lidibinosus) are New World robust capuchin monkeys widely used in medical research. Few data are available concerning hematological reference values for these species, with no studies available from the Northeast region in Brazil. The aim of this study was to determine the hematological reference values for healthy bearded capuchin monkeys and to analyze the influence of sex and age factors. Blood samples were collected from 50 healthy bearded capuchin monkeys housed in captivity. These were analysed for total erythrocyte, hemoglobin, leukocyte and platelet count, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC). When considering the age factor, significant differences were reported for total erythrocyte count, PCV, hemoglobin, total leucocytes, band neutrophils, eosinophils and lymphocytes (higher in juveniles). Significant sex-associated differences were noted for total erythrocyte count, PCV, hemoglobin (higher in males) and number of lymphocytes (higher in females).We have reported for the first time the hematological profile of bearded capuchin monkeys in captivity in the state of Paraíba, Brazil. These results can contribute for a better understanding of the normal physiology of capuchin monkeys, while demonstrating that factors such as sex and age influence hematological parameters should be taken into consideration in the hematological evaluation of this species.
Highlights
Cebus libidinosus, New World tufted capuchin monkeys, were reclassified in 2015 as Sapajus libidinosus, after a phylogenetic reconstruction (MARTINS et al, 2015).Capuchin monkeys are widely used in medical research, especially in areas such as immunology, pharmacology, physiology and neuroscience (TERPSTRA et al, 1991; LARSSON et al.,1997).Clinical and laboratory tests are highly important to ensure their good health and wellbeingApproved 08.21.18 Returned CR-2018-0065.R3 by the authorRural, v.48, n.10, conditions

Hematology tests stand out as an important tool, assisting clinicians in evaluating the animal’s health status and guiding them in establishing a diagnosis, prognosis and the adoption of appropriated therapies (KENNEDY et al, 1997). To the best of our knowledge, there are no studies from the Northeastern region of Brazil. The one research concerning bearded capuchin monkeys in Brazil was carried out in the Southern region, more than 3000km from the Northeast (FLAIBAN, 2008). The aim of the present study was to determine the hematological profile of bearded capuchin monkeys maintained in captivity in the state of Paraiba, located in the Northeastern region of Brazil, and to search for possible variations in hematological values related to sex and age
