The goal of this work was to document the cases of intestinal coccidiosis causes by Eimeria cameli in camel calves from Bikaner, India. Eimeria cameli is a cosmopolitan coccidium of camelids and has oocysts quite distinct from other coccidian species, in respect of larger size, very thick outer wall and considerably longer period of sporulation. The current work reports E. cameli from camel calves of a farm in Bikaner, India and makes some notes on the sporulation process, apart from the unsporulated oocyst morphology. Two out of the 34 faecal samples of camel calves under 2 years of age had unsporulated oocysts of E. cameli, which were recovered by sedimentation. Noteworthy in the morphological study the identification of an enlarged region in the inner layer of the oocyst wall, always in the opposite end of the micropyle. The sporulation time recorded in the present study was 19 days at 37 degrees C. Unexpectedly, some oocysts not sporulate even after 30 days in appropriate conditions of sporulation at room temperature even when kept in Petri dishes under aeration. The present study clearly determines the sporulation process of Eimeria cameli oocysts from dromedary camel.
