A project was conducted to study the prevalence, clinical signs, treatment response and necropsy findings in equines suffering from Surra in Gujranwala. For this purpose, 34334 animals brought to the Brooke Hospital for Animals were tested over a five year period from April, 1997 to December, 2002. The data showed that out of 34334 animals tested, 1151 were positive for the disease, showing a prevalence of 3.35 per cent. The clinical and necropsy findings were characteristics for the disease. Out of 1151 infected animals, 1129 (98.09 per cent) responded to isometamedium chloride and recovered while only 22 (1.91 per cent) died.

Key words: Surra, clinical findings, treatment, equines.
