POTENTIAL RISKS OF THE SPREAD OF ANTIBIOTIC-RESISTANT MICROORGANISMS AND ANTIBIOTIC-RESISTANCE GENES IN POTABLE WATER - HUMAN ORGANISM CHAIN.

Objective: The aim: Determination of circulation interrelations between antibiotic-resistant microorganisms of Enterobacteriaceae family and their resistance genes in clinical strains and potable water samples taken in Uzhhorod and Uzhhorod district.

Patients And Methods: Materials and methods: We carried out generic identification of the microorganisms isolated from clinical samples of the oral cavity of 64 patients suffering from periodontal inflammatory diseases, and potable water samples taken from sources of public centralized and decentralized water supply; the isolated microorganisms were tested for antibiotic sensitivity by the Kirby-Bauer disc diffusion method according to EUCAST. With the help of molecular-genetic methods, the total DNA of potable water was isolated and tested for the presence of the following genetic resistance determinants: carbapenems blaNDM; blaOXA48-like; tetracyclines blaTet-M; cephalosporins blaCTX-M.
