Bacteriocarriage of the Siberian weasel (Mustela sibirica) in the Transbaikal Territory

The paper presents the results of research aimed at identifying bacterial carriers in the Siberian weasel living in the Trans-Baikal Territory. The studied material was obtained in the Akshinsky mu nicipal district of the Trans-Baikal Territory as a result of seasonal hunting. A total of 7 strains of mi crobial cultures were obtained. Morphological, cultural, tinctorial, biochemical, as well as pathogenic properties and their relationship to various antibiotics were studied in all the isolated microbial strains. Based on the analysis and comparison with the classical characteristics of the biological properties of the isolated microbial cultures, the circulation of the following microorganisms Listeria monocyto genes, Escherichia coli, Staphilococcus aureus with classical biological properties were found in the Siberian weasel. Pathogenic properties were observed in the strains of Escherichia coli and Staphilo coccus aureus. It was not possible to isolate microbial cultures from parenchymal organs in three weasels, as the animals turned out to be sterile. All the isolated bacterial strains had hemolytic activity. The Escherichia coli strain caused the death of laboratory white mice. In our opinion, these microor ganisms can cause the disease escherichiosis in the population of the Siberian weasel and cause the deaths of a significant number of these animals. Thus, the bacterial cultures isolated in the course of the research from the Siberian weasel have epizootic and epidemic significance, they can cause the development of acute infectious diseases in representatives of wild fauna, as well as in humans. The obtained results can be used in long-term forecasting of the occurrence of infectious diseases in the population of wild animals, epizootological geographical demarkation of the territory of the region, when developing a plan of veterinary and preventive measures in hunting farms and on publicly accessible hunting grounds.
