Abstract: A common parasitic disease carried by vectors is trypanosomiasis, also known as Surra. It is a hemoparasitic disease that induces adverse effects on the health and working capability of infected animals. A 5-year-old buffalo was presented at a veterinary hospital in Guntur, Andhra Pradesh, with a history of circling movements, loss of appetite, pressing of the head against the manger and swelling of the forelimbs. Upon clinical examination, the buffalo exhibits a temperature of 106^◦F with a pale conjunctival mucous membrane. A thin blood smear stained with Giemsa stain was examined under a microscope to make the diagnosis, which showed the presence of the intercellular flagellated hemoprotozoan Trypanosoma evansi. Buffalo was treated with a single dose of quinapyramine sulphate and chloride (triquin) at a dose rate of 5 mg/kg body weight via the subcutaneous route, followed by supportive drugs. The clinical signs completely disappeared after five days of therapy. After five days of treatment, the animal's blood was drawn and a microscopic inspection showed no evidence of parasitemia.
