| Abstract: | The detailed study of 179 strains, considered to be typical and atypical representatives of Y. enterocolitica upon their isolation, has been carried out. Of these, 129 strains have been found to belong to Y. enterocolitica with their typical biochemical properties and 50 strains, to new Yersinia species. The ecological sources of all the isolated strains are indicated. The necessity of the thorough epidemiological, clinical and laboratory study of the etiological role of Yersinia in acute intestinal diseases in humans is pointed out. |
