Abstract
The article analyzes the literature data and own research on the distribution and species composition of helminths and eimeria in brown bears in the East Kazakhstan region. The aim of the study was to identify a type of helminth in American black bears (Ursus americanus). The relatively low level of parasite detection in this study is in line with expectations for populations of brown bears (Ursus arctos) living in large areas. Tasks: to identify and study the type of helminths in the brown bear. On the territory of the Russian Federation, the brown bear has 17 species of helminths (including 3 species of trematodes and 14 species of nematodes) and 2 species of protozoa. Most of the discovered species of helminths, eimeria, cryptosporidia both in zoos, circuses, and in the natural habitat of brown bears: European, Siberian and Far Eastern parts of Russia have epizootological and epidemiological significance. For the first time, we registered bears in the territory of the Republic of Kazakhstan.
