[The significance of the incidence of coccidia of the Cryptosporidium species in the etiopathogenesis of neonatal diarrhea syndrome and enteritis in calves on the basis of simultaneous histopathologic and parasitologic studies].

In 1985, a histopathological examination was conducted in the ileum and a parasitological examination in the ileum and rectum of 345 emergency slaughtered calves.
