Stomach compartments of the reindeer and other related wild hoofed mammals are a habitat of very different in morphology and systematic position types of infusorians. However the fauna and life cycles of the majority of the known types of the endobiotical infusorians living in the animal stomach as well as their influence on the organism of the owner have not been sufficiently studied. Thus, studying of the fauna, features of biology and ecology of infusorians in wild ruminants inhabiting different regions of the world deepens our knowledge about these peculiar and well adapted to the organism of their owner protozoa. The present research is devoted to the study of the fauna, biological and ecological features, and the number of infusorians in the stomach of the reindeer widespread on the territory of Chukotka Autonomous Region. In order to achieve the main goal we set the following tasks: to research the species composition of the infusorians found in the digestive tract of the reindeer, to describe the quantitative structure of the infusorians, to define spatial distribution of the infusorial fauna in the digestive tract. The article contains original data on the species composition and the number of infusorians in different compartments of a reindeer stomach. 16 types of infusorians are singled out. This figure has been confirmed by other protozoologists engaged in the study of the infusorial fauna of the reindeer in different natural zones and habitats.
