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.
