[Morphobiological characteristics of Hasstilesia ovis (Trematoda: Brachylaimidae) and the pathomorphological changes it causes in sheep intestines].
Data on the life cycle of the trematode Hasstilesia ovis are given for the second time in order to point to the errors occurring in helminthological literature. The species has one intermediate host, the terrestrial molluscs Pupilla muscorum and Vallonia costata. Cercariae are turned into metacercariae without leaving molluscs. Pathomorphological changes in the intestine of the sheep caused by these parasites are described. The authors came to the conclusion that the parasites have a pathogenic effect upon the host and cause a disease which should be called hasstileosis.
