The salivarian trypanosome, Trypanosoma evansi, commonly called as surra in India causes major disease in camels, equines and dogs and in which it can often be fatal in the absence of treatment. In this manuscript a case study of trypanosome infected dog is detailed. A Female Dobermann dog of three years age was reported to a private Veterinary clinic at Proddatur, the Rayalaseema region of Andhra Pradesh, India with the clinical symptoms of pyrexia (105ºF), severe anemia and pale mucous membrane with lateral recumbency. The dog was adopted in a farm house along with few buffaloes and often fed with cooked beef. The blood was screened for hemprotozoan parasites by wet blood film (WBF) and Leishmann’s staining technique and the case was confirmed as Trypanosoma evansi by microscopic examination. Complete blood profile was carried out manually, in which hypochromic regenerative anaemia was noticed. The animal was initially stabilized with intravenous iron sucrose infusion; soon after,

Canine Vector borne disease, Iron sucrose infusion, Trypanosoma evansi.

Severe to moderate reduction in TEC, PCV, Hb and TLC values with marginal neutrophilia, relative lymphocytopenia and hypochromic anaemia was the common findings of canine trypanosomosis, however the differential diagnosis of occurrence of similar haemogram in other blood protozoan diseases is mandatory. It is recommended to stable the trypanosomosis infected anemic dog with intravenous iron sucrose therapy before the administration of diminazine aceturate. Further, diminazine aceturate is strictly dose specific in canidae family and lethal to exceed 3.5mg/kg body weight. Concomitantly, the dose of diminazine can be extended up to 7.0 mg/kg to other cloven footed animals by deep intramuscular route.
