Abstract

The authors studied the prevalence of cryptosporidiosis by screening 455 bovine fecal samples collected from five different organized dairy farms and veterinary hospitals located in and around Bangalore, South India. The fecal samples were examined by Sheather’s sugar flotation method for detection of oocysts, 5.71 percent were found positive for cryptosporidiosis. The species were identified as Cryptosporidium parvum and Cryptosporidium andersoni based on the morphology and micrometry of the oocysts by Modififi ed Ziehl- Neelsen staining, Kinyoun’s staining method and Safranin methylene blue staining methods. The prevalence and intensity of cryptosporidiosis was found more in calves of less than one month of age compared to adults and more frequently seen in diarrheic than in non-diarrheic samples. The highest prevalence of cryptosporidiosis was found in the HF crossbreeds followed by Jersey cross. No cryptosporidium oocysts were found in Deoni,
Surti buffalo calves and non-descript breeds. The sex wise prevalence of cryptosporidiosis was observed more in females compared to males. A statistically significant difference was found between sexes, age and breed prevalence of cryptosporidiosis. Finally it was concluded that the prevalence of cryptosporidiosis in bovines in this region is under diagnosed and the sub clinical status of infection is potentially high.
