In Mice, Crypotsporidium muris affecting the4 gastric glands and cryptospordium parvum in the small intestine. Since 1971 cryptoporidium has been found to be associated with bovine dairrhoea which stimulated veterinary interest. Now cryptosporidium is recognised as an important parasite with worldwide distribution. Anderson (1991) obtained C. muris like occysts in camel faeces, inoculated them per os into mice and demonstrated acid-fast-positive oocysts in faecal smears as well as colonization of gastric glands, however identical experiments using similar oocysts from cattle produced no evidence of trasmission. These findings place in doubt the likelihood that the indistinguishable oocysts from different hosts are the same species of cryptosporidium. Following the initial report of human cryptosporidosis in Iran, anothe rreport indicated that healthy people, cows and neonatal calves excreted C. parvum oocysts, thus consdituting a potential zoonotic problem. And then another report indicated the strong possibility of asymptomatic zoonotic transmission due to prologed association of shepherds with their sheep. In view of the increasing evidence of pathogenicity of C. muris like infection in animals, the present study was undertaken to determine the presence or absence of C. muris like oocysts in the faeces of cattle and camel in various town in Iran. At one of these towns, gastrointestinal samples of mice were also examined to determine the possible role of mice in transmission of oocysts.
