Abstract:
Bovine theileriosis is a fatal tick borne haemoprotozoan disease of cattle caused by an apicomplexan parasite Theileria spp. In India Theileria annulata is an important species that infects cattle and causes severe economic loss. The present case elucidates the successful management of bovine theileriosis in the cattle at field level. A four year old female Jersey crossbred cattle was presented with anamnesis of not taking feed, fever and tick infestation. On clinical examination the animal was found to be dull and depressed, had pyrexia (106 ˚F), pale mucous membrane, petechial haemorrhage on the vaginal mucous membrane, enlarged pre-scapular lymph nodes and severe tick infestation. Examination of peripheral blood smear revealed the presence of intra-erythrocytic piroplasms of Theileria organism. The animal was treated with Buparvaquone (Bupamax) deep IM, @ 2.5 mg/kg BW, accompanied with supportive therapy (iron supplement).
