Coccidiosis is one of the economically important disease-causing heavy morbidity and mortality in young animals caused by a single-celled parasite called coccidia. A month-old non-descript cow calf was presented with symptoms of hemorrhagic diarrhoea, anorexia, dullness and dehydration. By detecting coccidial oocysts on coprological examination, the case was diagnosed as winter coccidiosis. The calf was successfully treated with Sulphadiazine and Trimethoprim @ 30 mg/kg b.wt coupled with supportive therapy. An uneventful recovery occurred following 3 days of treatment and the faecal samples showed no evidence of oocysts.
