Plasmid-mediated quinolone resistance by genes qnrA1 and qnrB19 in Salmonella strains isolated in Brazil.
Considering the importance of the mechanisms involved in quinolone resistance, this study evaluate the presence of PMQR in 126 epidemic and not epidemic strains of Salmonella spp. It was noted that presence of PMQR, by itself, did not generate resistance to ciprofloxacin; but detection of qnr genes in Salmonella spp. and the identification of the qnrB19 variant in a strain of poultry origin ale...

Sir, Chromosomal mutations in the topoisomerase II gene gyrA and altered drug accumulation were considered to be the only mechanisms of quinolone resistance until 1998, when the plasmidmediated quinolone resistance gene, qnrA, was described in an isolate of Klebsiella pneumoniae. Since then, other plasmidborne resistance genes, qnrB, qnrS (and their variants), aac(60)-Ib-cr and qepA, have been ...

identical pattern (pattern A), whereas Ec 461 was different (pattern B) by both of the typing methods. The presence of the OXA-2 gene has been frequently detected in Pseudomonas and it was first reported in E. coli from Israel in 2005. To the best of our knowledge, the presence of this gene in E. coli is the first report from India and the second in the world. The implication/s of the recent de...

متن کاملAssociation of Transferable Quinolone Resistance Determinant qnrB19 with Extended-Spectrum β-Lactamases in Salmonella Give and Salmonella Heidelberg in Venezuela
Four nontyphoidal Salmonella strains with resistance to extended-spectrum cephalosporins and nonclassical quinolone resistance phenotype were studied. Two S. Give were isolated from pediatric patients with acute gastroenteritis, and two S. Heidelberg were recovered from raw chicken meat. Phenotypic characterization included antimicrobial susceptibility testing and detection of extended-spectrum...
