ABSTRACT

The present work was carried out to study the morphology of Cryptosporidium oocysts recorded in diarrhoeic calves. A total of 148 faecal samples of diarrhoeic calves were screened for Cryptosporidium oocysts by modified Ziehl-Neelsen staining technique for morphological studies. Out of 148 samples, 31 (20.9%) samples were found positive for oocyst of Cryptosporidium species. The morphometric analysis revealed that the range of longitudinal diameter of the oocysts were 5.05±0.349-5.275±0.248 µm and the transverse diameter of the oocysts were 4.67±0.354-4.775±0.184 µm with a shape index (length/width) of 1.08-1.104.Based on oocyst dimension and shape index, it was assumed that ovoid and sub-spherical oocysts belonged to Cryptosporidium parvum.
