High Prevalence of Plasmid-Mediated Quinolone Resistance among ESBL/AmpC-Producing Enterobacterales from Free-Living Birds in Poland.

ABSTRACT: In this study, we investigated the occurrence of plasmid-mediated quinolone resistance (PMQR) in extended-spectrum β-lactamase- (ESBL) and/or AmpC-type β-lactamase-producing Enterobacterales isolates from free-living birds in Poland. The prevalence of the qnrB19 gene was 63%, and the distribution of isolates in terms of bacterial species was as follows: 67% (22/33) corresponded to Escherichia coli, 83% (5/6) to Rahnella aquatilis, 44% (4/9) to Enterobacter cloacae and 33% (1/3) to Klebsiella pneumoniae. The qnrB19 gene was also found in a single isolate of Citrobacter freundii. The molecular characteristics of qnrB19-positive isolates pointed to extended-spectrum beta lactamase CTX-M as the most prevalent one (89%) followed by
