Vertically Transmitted T. Annulata Induced Corneal Opacity In Bovine Calf

The present case reports an unusual case of vertically transmitted Theleria annulata induced corneal opacity in day old crossbred cattle calf. The case was presented with history of severe dejection, sternal recumbency, anorexia, pyrexia, clouding of eye, and no response to ceftriaxone and meloxicam administration for last 2 days. Clinical examinations revealed absence of prescapular lymphadenopathy and presence of exophthalmos and corneal opacity. Fecal floatation, complete blood count, blood smear, and lymph node biopsy examination were performed to make a confirmatory diagnosis. Blood smear reveals presence of several piroplasm organisms in erythrocytes. Case was efficiently and safely managed by using single deep Intramuscular injection of Buparvaquone at the rate of 2.5 mg/kg body weight along with long acting oxytetracycline @ 20 mg/kg body weight every third day along with supportive therapy. The combination was well tolerated by the calf with complete recovery with subsidence of corneal opacity within one week.
