Hematological Data of Healthy and Natural Trypanosoma evansi Infected Camels (Camelus dromedarius) in Sokoto, Nigeria

Abstract

Presence of trypanosomes were determined using thick and thin blood smears, and differential centrifugation by the microhematocrit technique. Some hematological parameters were obtained by capillary microhematocrit centrifugation, Sahli and hemocytometer methods in blood samples collected from 100 camels in Sokoto, Nigeria. Fourteen percent of camels were infected with Trypanosoma evansi. The mean values for packed cell volume, concentration of hemoglobin and total red blood cell count were relatively lower in T. evansi-infected camels, even though these were not statistically significant. A slightly higher but not significant white blood cell counts were observed in the T. evansi-infected camels. The mean corpuscular hemoglobin concentration was significantly lower in T. evansi-infected camels. However, there was no significant variation in the mean cell volume between the groups.
