This research is dedicated to a relevant topic in veterinary medicine, which is connected with studying of specific features in systems that are responsible for productive and reproductive functioning in cattle. The reported study was funded by RFBR and Sverdlovsk region, project number 20-416-660004 «Molecular genetic and phenotypic characteristics of the microbiota in the reproductive system of cattle». Samples of secretory product of the mammary gland and cervical swabs of 81 cows and 5 dairy farms of Sverdlovsk region (Russia) were analyzed. A number of pathogenic and opportunistic microorganisms (S.aureus, S.lugdunensis, Streptococcus spp., Enterobacter spp., Enterococcus faecium, Enterococcus faecalis, Escherichia coli, Proteus vulgaris, Bacillus spp.)and mold fungi (Mucor spp., Penicillum spp., Aspergillus spp.) were isolated as a result of microbiological testing of the biological samples. The microbiota structure of the reproductive tract and the lacteal gland is demonstrated in physiologically normal state and during the inflammatory process. The phenotypic characteristic of isolated microorganisms, as well as evaluation of biochemical parameters and pathogenicity were indicated.
