The MIC tests were performed by a broth microdilution method according to the European Committee on Antimicrobial Susceptibility Testing standards (EUCAST, http://www.eucast.org). was estimated by three independed biological repetition.
MDR – acquired resistance to more than 3 groups of antibiotics; ESBL + - Extended-Spectrum Beta-Lactamases, S – sensitive, no acquired resistance.
