[Antibiotic Resistance Genes in Cattle Gut Microbiota: Influence of Housing Conditions].

Resistance to antimicrobial drugs is an urgent problem not only in public health, but also in animal husbandry. The widespread use of antimicrobials in feed additives is one of the main reasons for the rapid spread of antibiotic resistance in the microbiota of the gastrointestinal tract of farm animals. To characterize antibiotic resistance genes (resistome), we performed metagenomic analysis of the feces of 24 cattle from different regions of Russia, including cows of different breeds and yaks.
