Prevalence of Cryptosporidium infection in cattle in Isfahan, Iran.
Cryptosporidium are commonly identified as intestinal pathogens in humans and animals. Fecal samples from 480 cattle randomly selected from 30 regions in Isfahan, Iran, were examined to investigate the prevalence of Cryptosporidium infection. Cryptosporidium oocysts were identified by using sheather's concentration and the Ziehl-Neelsen modified staining technique in 30 of 480 cattle ranging from less than 6 mo of age to older than 1 yr of age. Infected animals were found in 86.6% (26/30) of regions investigated. Overall prevalence of infection was 6.25%, but higher in cattle less than 6 mo of age (10.8%) and this was statistically significant (P<0.05). Both sexes of cattle were infected with Cryptosporidium parasites, but prevalences were higher in diarrheic (56.7%) than in non-diarrheic (39%) cattle. Cryptosporidium appears to be prevalent in cattle in Isfahan.
