  4. Abstract:
  5. This study describes some epidemiological and patho-physiological aspects of Trypanosoma evansi (causative agent of “surra”) infection in camels (n=255) and Nili Ravi buffaloes (n=233). Clinical ailments like fever, shivering, edema of pads and urticarial swelling were observed in infected animals. Overall prevalence of T. evansi infection in buffaloes was 9.01 and 15.12% based on blood smear examination and PCR, respectively, while in camels, the prevalence was 10.58 and 15.29% based on smear examination and PCR, respectively. Results on epidemiological data did not indicate significant association of different factors of hosts with prevalence of T. evansi. Hematological parameters including hematocrit, mean corpuscular volume (MCV), leukocyte counts, neutrophils, eosinophils and monocytes increased significantly (P<0.05) while erythrocyte counts, hemoglobin (Hb) concentration, mean corpuscular hemoglobin concentrations (MCHC), and lymphocytes decreased significantly in infected buffaloes. In infected camels, leukocyte counts, neutrophils, eosinophils, monocytes, and basophils increased significantly (P<0.05) while erythrocyte counts, Hb concentration, hematocrit, and lymphocytes decreased significantly. Serum biochemical parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in infected camels while ALT and ALP, LDH, and Lipid per oxidation product (LPO) in infected buffaloes increased significantly (P<0.05). Results showed significantly decreased values of AST, total proteins, magnesium, calcium, and phosphorus in infected buffaloes. © 2021, University of Agriculture. All rights reserved
