Plasmid-mediated resistance to cephalosporins and fluoroquinolones in various Escherichia coli sequence types isolated from rooks wintering in Europe.

ABSTRACT: Extended-spectrum-beta-lactamase (ESBL)-producing, AmpC beta-lactamase-producing, and plasmid-mediated quinolone resistance (PMQR) gene-positive strains of Escherichia coli were investigated in wintering rooks (Corvus frugilegus) from eight European countries. Fecal samples (n = 1,073) from rooks wintering in the Czech Republic, France, Germany, Italy, Poland, Serbia, Spain, and Switzerland were examined. Resistant isolates obtained from selective cultivation were screened for ESBL, AmpC, and PMQR genes by PCR and sequencing. Pulsed-field gel electrophoresis and multilocus sequence typing were performed to reveal their clonal relatedness. In total, from the 1,073 samples, 152 (14%) cefotaxime-resistant E. coli isolates and 355 (33%) E. coli isolates with reduced susceptibility to ciproflox
