A cross-sectional study was conducted to determine the prevalence of bovine cryptosporidiosis using 110 fecal samples of crossbred diarrhoeic calves from two different areas (Muktagacha, Mymensingh and Shajadpur, Sirajgonj) in Bangladesh during April 2012 to September 2014. The fecal samples were screened by rapid detection kit and confirmed by Modified Ziehl- Neelsen staining, and polymerase chain reaction (PCR). The positive samples along with standard positive control yielded 1325bp band on PCR. The overall prevalence of cryptosporidiosis in crossbred calves was 28.18% (31/110) by rapid detection kit. The higher prevalence of cryptosporidiosis was found in the calves from Shajadpur (29.76%) than the calves from Muktagacha (23.08%).The prevalence of cryptosporidiosis was significantly (p<0.001) higher in calves between 1-2 months (70%) age group than less than one month age group (24.49%). Cryptosporidiosis was not observed in calves over two months age. The prevalence of cryptosporidiosis was higher in males (34.75%) than females (24.64%) although not significant statistically. It is evident that the prevalence of cryptosporidiosis in bovine in these areas is under diagnosed and the clinical status of infection is potentially high.
