title: [Rodents trichomonads: morphology, life cycle and several ecologic features (Polymastigina)].
abstract: Some morphological and cytochemical methods were applied to the study of the life cycle of Trichomonas parasitizing the intestine of various rodents. The comparative study of trophonts morphology showed that the only species of the genus Trichomonas--T. muris inhabits the intestine of mice, rats, field-voles, hamsters and susliks. The life cycle of T. muris includes three morphologically different stages: trophonts, pseudocysts and cysts. The pseudocysts and cysts are the infectious stages of T. muris. All rodents ingest them together with their food. The cysts of T. muris can survive for a long time (6 months and more) in the environment under the conditions of various temperature and humidity.
