ABSTRACT
BACKGROUND: Cebus flavius is a New World Monkey found in the northeast of Brazil, listed as critically endangered. So far, no hematologic or blood chemistry reference intervals have been determined for this species. METHODS: Hematologic and biochemistry reference values were determined for 20 clinically healthy C. flavius, kept in captivity in the Wild Animals Screening Center, João Pessoa, Paraíba, Brazil. The influence of gender and age on these variables was evaluated. RESULTS: Considering sex, significant differences are found for the total count of erythrocytes, hematocrit, hemoglobin, mean corpuscular hemoglobin, and creatine kinase. Regarding the age, levels of creatinine and alanine aminotransferase are significantly higher in adults and levels of creatine kinase and calcium are significantly higher in juveniles. Considering age, no hematologic differences were found. CONCLUSIONS: The factors age and gender had influence on some hematologic and blood chemistry variables and should not be neglected for a correct blood interpretation.
