The researches studied opportunistic microbiocenoses at different technological sites of a commercial dairy farm in a three-year dynamics. The composition and sensitivity of the opportunistic pathogenic microflora to antibiotics were determined. It was established that the generic and species composition of the core of microbiocenoses was represented by typical opportunistic strains and was characterized by relative constancy at each site. The most common representatives were Enterococcus spp., P. aeruginosa, Proteus spp., S. aureus, E. coli, and C. albicans. A comparative analysis of antibiotic resistance in 2017 and 2020 revealed an upward trend in AMR. At all the examined sites, an increase in the proportion of microorganisms with reduced sensitivity to three or more antibiotics was revealed. An increase in the number of multi-resistant isolates was found in the calve site.
