Hematologic values of the wild-caught karyotype V owl monkey (Aotus vociferans)

Blood samples from 35 wild-caught owl monkeys (Aotus vociferans, karyotype V) were analyzed to estimate reference intervals of hematologic variables for the species. Findings indicated that distributions were abnormal for leukocytes, neutrophils, eosinophils, basophils, and monocytes. Statistically significant sex differences, too small to be of clinical importance, were found in values for mean cell hemoglobin concentration, leukocytes, and basophils. Reference intervals for the hematologic variables were calculated by the nonparametric percentile estimation method. Comparison of hematologic reference values for wild-caught A. vociferans with those of A. nancymae revealed statistically significant differences for packed cell volume, mean cell volume, leukocytes, eosinophils, basophils, and platelets. These differences also appeared too small to be of clinical significance.
