Prevalence of plasmid-mediated quinolone resistance in Escherichia coli isolated from diseased animals in Taiwan
Escherichia coli (E. coli) is a zoonotic pathogen that often causes diarrhea, respiratory diseases or septicemia in animals. Fluoroquinolones are antimicrobial agents used to treat pathogenic E. coli infections. In this study, 1,221 E. coli strains were isolated between March, 2011 and February, 2014. The results of the antimicrobial susceptibility testing showed a high prevalence of quinolone ...
متن کاملExtended-Spectrum-Beta-Lactamases, AmpC Beta-Lactamases and Plasmid Mediated Quinolone Resistance in Klebsiella spp. from Companion Animals in Italy
We report the genetic characterization of 15 Klebsiella pneumoniae (KP) and 4 isolates of K. oxytoca (KO) from clinical cases in dogs and cats and showing extended-spectrum cephalosporin (ESC) resistance. Extended spectrum beta-lactamase (ESBL) and AmpC genes, plasmid-mediated quinolone resistance (PMQR) and co-resistances were investigated. Among KP isolates, ST101 clone was predominant (8/15,...
متن کاملAssociation of plasmid-mediated quinolone resistance and virulence markers in Escherichia coli isolated from water.
This work aimed to investigate the association of the carriage of plasmid-mediated quinolone resistance (PMQR) genes, the virulence potential encoded in pathogenicity islands (PAIs) and the phylogenetic background in Escherichia coli strains isolated from waters of diverse origin. Antimicrobial susceptibilities were determined by the disc diffusion method. Screening for PMQR (qnr, aac(6')-Ib-va...
متن کاملPlasmid-mediated quinolone resistance in clinical isolates of Escherichia coli from Shanghai, China.
Although quinolone resistance usually results from chromosomal mutations, recent studies indicate that quinolone resistance can also be plasmid mediated. The gene responsible, qnr, is distinct from the known quinolone resistance genes and in previous studies seemed to be restricted to Klebsiella pneumoniae and Escherichia coli isolates from the University of Alabama in Birmingham, where this re...
متن کاملPlasmid-mediated quinolone resistance pump QepA2 in an Escherichia coli isolate from France.
One hundred twenty-one extended-spectrum beta-lactamse-producing enterobacterial clinical isolates were screened for the qepA gene. A single CTX-M-15-positive Escherichia coli isolate (0.8%) that produced the putative pump QepA2 was identified. This qepA2 gene was located onto a 90-kb mobilizable plasmid that conferred reduced susceptibility to hydrophilic fluoroquinolones.
