Abstract: Parasitological, serological and biochemical tests were used to determine Trypanosoma evansi infection in 170 horses and 150 camels sampled from Punjab region, Pakistan. The micro-Haematocrit Centrifugation Technique was used as gold standard method. Wet blood films, thin stained smears and thick stained smears showed a sensitivity of 0.8 and a specificity of 1. Positive and negative predictive values were 1 and 0.99, respectively. Serology using Suratex (R) showed a sensitivity of 1 and a specificity of 0.99. Positive and negative predictive values were 0.83 and 1, respectively. Biochemical tests showed a very low positive predictive value (around 0.38). None of the equines resulted positive at any method. In contrast, 5 (3.3%) and 6 (4%) camels were positive at parasitological and serological examination, respectively. These results seem to indicate that T. evansi infection has a relatively low prevalence in the Punjab region.
