Plasmid-mediated qnr genes have been reported in bacteria worldwide and are widely associated with other relevant determinants of resistance in multiresistance plasmids. Here, we provide an update on a previously described multiplex PCR in order to detect all six qnr families (including qnrA, qnrS, qnrB, qnrC, qnrD, and qnrVC) described until now. The proposed method makes possible the screening of these genes, reducing cost and time, and it may demonstrate an underestimated prevalence of the latest variants described.
