BackgroundQnr genes are known to confer a low-level resistance to fluoroquinolone in Enterobacteriaceae. They are often found on the same resistance plasmids as extended spectrum -lactamase (ESBL) and constitute the most common antibiotic resistance mechanism. This study aimed to detect the presence of qnr genes in ESBL-producing E. coli and Klebsiella spp.MethodsFrom May 2013 to July 2015, 91 E. coli and 64 Klebsiella spp. strains with phenotypic resistance to quinolone were collected from several specimens and analyzed for the detection of qnrA, qnrB, qnrS genes and the -lactamase resistance genes (blaCTX-M, blaTEM, blaSHV) using simplex and multiplex PCR.ResultsIn the present study, 107 (69%; 61 E. coli and 46 Klebsiella spp.) of 155 bacterial strains tested were found harboring at least one qnr gene consisting of 74 (47.74%) qnrB, 73 (47.10%) qnrS and 4 (2.58%) qnrA. Of the 107 strains encoding qnr genes, 102, 96 and 52 carried CTX-M1, TEM and SHV type ESBL respectively.ConclusionThis study identified quinolone resistance (qnr) gene in ESBL-producing E. coli and Klebsiella spp. in Togo. These finding which suggest a possible resistance to quinolone are of high interest for better management of patients and control of antimicrobial resistance in Togo.
