Experimental cryptosporidiosis in mice, calves and chicken.

Experimental infections attributed solely to Cryptosporidium were carried out in newborn SPF mice, calves and chicken in order to study the prepatency, patency and incubation periods, describe the clinical symptoms and find and describe any correlations between the association of Cryptosporidium with the intestinal mucosa and presence of pathological lesions. The paper also gives the clinical and paarsitological parameters of Cryptosporidium infection of calves from a field survey and compares them to the results of experimental study.
