Hematological and biochemical changes in water buffalo calves (Bubalus bubalis) infected with Trypanosoma evansi

Four water buffalo calves (Bubalus bubalis) were each inoculated intravenously with 106T. evansi (camel isolate) and the fifth calf kept as non-infected control. The blood and sera of all calves were examined every 4 days during the first month post-inoculation (pi) and then once weekly until the end of the experiment (88 days pi). They were examined for hematological and biochemical changes, liver and kidney function tests. Hemoglobin concentration (Hb%), packed cell volume (PCV) and red blood cell count were significantly decreased. Total leucocytic count, lymphocytes and monocytes showed significant increase. Liver function tests revealed significant elevation in the activity of lactate dehydrogenase enzyme (LDH), globulin, total biliruben and indirect biliruben while alkaline phosphatase enzyme showed significant decrease. Kidney function tests revealed significant decrease of both creatinine and urea.
