Abstract

SILVA, T.D.P. et al. Manual and automated blood cells count in ocelots (Leopardus pardalis - Linnaeus, 1758). Arq. Bras. Med. Vet. Zootec. [online]. 2017, vol.69, n.5, pp.1191-1197. ISSN 1678-4162.  http://dx.doi.org/10.1590/1678-4162-9299.

Automated equipment, whose use is established in hematology of domestic animals, is not yet routinely used in blood cells count of wildlife, due to lack of studies that validate its use. The purpose of this study was to evaluate the automated technique for blood cells count of ocelots (Leopardus pardalis), comparing it with the manual technique. Blood samples were collected from eight ocelots, which were submitted to counting of erythrocytes, leukocytes, platelets and packed cell volume by the standard manual method and by the device VET ® 2800 BC with the configuration for domestic cats. The results were evaluated using the t test for paired data and the techniques submitted to Pearson correlation. The automated technique showed statistically similar results to erythrocytes and leukocytes. Significant difference was found only for packed cell volume between the manual and automated techniques, but the correlation was high. Although there was no significant difference between the techniques for platelets, the correlation was low. We concluded that the 2800 BC VET ® device with the configuration for domestic cats is a reliable technique in performing the erythrocyte and leukocyte counts for ocelots. The device may be used to determine packed cell volume, provided the correction is made. The manual technique is recommended for the platelet count.
