Diagnosis and Therapeutic Management of Theileriosis in Cattle Calves

The present investigation was carried out among ten cross-bred Cattle calves of age between 1-5 months which were presented to Veterinary Clinical Complex of College of Veterinary and Animal Science, Bikaner with the history of anorexia, high fever, diarrhoea and tick infestation. Upon clinical examination pale mucous membrane, enlarged prescapular lymph nodes and increase in respiration rate and pulse rate were found. Blood samples were collected from jugular vein in vacutainers containing EDTA for haemogram. Microscopic examination of Giemsa stained thin blood smears revealed piroplasms in erythrocytes and lymph node aspirate smears revealed presence of schizonts (Koch's blue bodies) in lymphocytes. Upon haematological examination it revealed that the decrease in haemoglobin, total erythrocyte count, packed cell volume and lymphocytes, however increase in total leukocyte count and neutrophils. After confirmation of Theileriosis in calves Buparvaquone was administered at the dose rate of 1ml/20kg body weight via intramuscular route. Eight calves were very well responded to the treatment but two calves were eventually died due to severe anaemia.
