- Abstract
Research of opportunistic microbiocenosis in livestock enterprises of the Ural region was conducted. Dairy farms located in areas with different levels of technogenic contamination of agrobiocenoses with metals Cu, Cd, Fe, Zn, Hg, As, Pb and radionuclides 90Sr, 237Cs 210Pb were studied. The proportion of S. aureus strains in the opportunistic microbiocenosis of different farm departments was analyzed, and the selected strains were also tested for sensitivity to the antibiotics most frequently used in the industry. It was found that on all the studied farms predominate S. aureus strains with reduced sensitivity to antibiotics, the most common in animal husbandry practice. It was discovered that the proportion of strains of S. aureus resistant to rifampicin, cefazolin and tetracycline is increasing in areas with discernible technogenic contamination of agrobiocenosis. The share of multi-resistant strains of Staphylococcus aureus, resistant to 3 or more classes of antibiotics, was also maximum in ecologically unfavorable areas.
