Antimicrobial Resistance Profile of spp. Isolates from Retail Meat Samples under -Selective Conditions.

strains are widely present in the environment. Some antimicrobial-resistant strains of this genus have been implicated in infections acquired in hospitals. Genetic similarities have been reported between strains in nosocomial infections and those isolated from foods. However, the antimicrobial resistance of strains in foods, such as meat, remains unclear. This study initially aimed to isolate strains; instead, strains of the genus were isolated from meat products, and their antimicrobial resistance was investigated. In total, 58 strains were isolated from 381 meat samples. Of these, 32 strains (38.6%) were from beef, 22 (26.5%) from pork, and 4 (4.8%) from duck meat. Antimicrobial susceptibility tests revealed that 12 strains were resistant to more than one antimicrobial agent, whereas two strains were multidrug-resistant; both strains were resistant to colistin. Cephalosporin antimicrobials showed high minimal inhibitory concentration against strains. Resfinder analysis showed that one colistin-resistant strain carried ; this plasmid type was not confirmed, even when analyzed with PlasmidFinder. Analysis of the contig harboring using BLAST confirmed that this contig was related to of . The increase in antimicrobial resistance in food production environments increases the resistance rate of strains present in meat, inhibits the isolation of strains, and acts as a medium for the transmission of antimicrobial resistance in the environment. Therefore, further investigations are warranted to prevent the spread of antimicrobial resistance in food products.
