Abstract
- Aimed at reporting markers of plasmid resistance to qnr quinolones in clinical isolates of CTX-M beta-lactamase-producing enterobacteria, a descriptive study was conducted with isolates from the strain repository of TO-06/09 project of the National Children's Health Institute. 138 isolates were recovered. Antimicrobial susceptibility was determined by the diffusion disk method, and gene identification by polymerase chain reaction. Of the 138 isolates, 67 (48.5%) were genotypically positive for qnr proteins; of these, 38 (56.7%) had qnrB determinants and 48 (71.6%) had qnrS determinants. No isolate presented qnrA determinants. qnr determinants were detected in isolates containing CTX-M beta-lactamases in a non-exposed population. [ABSTRACT FROM AUTHOR]
