Plasmid-mediated quinolone resistance determinant qnrS in Enterobacter cloacae [PDF]

Clinical Microbiology and Infection, 2006
PCR was used to investigate the occurrence of the plasmid-encoded quinolone resistance determinants qnrA and qnrS among diarrhoeagenic enterobacterial isolates recovered from Hanoi, Vietnam, during the period March 2001 to April 2002. In total, 162 Escherichia coli isolates, 28 Shigella isolates and three Enterobacter cloacae isolates were negative for

Enantiomeric profiling of quinolones and quinolones resistance gene qnrS in European wastewaters [PDF]

Water Research, 2020
Wastewater-based epidemiology (WBE) was applied for the first time in seven cities across Europe with the aim of estimating quinolones consumption via the analysis of human urinary metabolites in wastewater. This report is also the first pan-European study focussed on the enantiomeric profiling of chiral quinolones in wastewater.

Plasmid-mediated quinolone resistance determinants in fluoroquinolone-nonsusceptible Escherichia coli isolated from patients with urinary tract infections in a university hospital, 2009–2010 and 2020

Journal of Global Antimicrobial Resistance, 2022
Objectives: This study aimed to characterize the plasmid-mediated quinolone resistance (PMQR) in fluoroquinolone nonsusceptible E. coli (FQNSEC) isolated from patients with urinary tract infections (UTIs) in 2019–2010 and 2020. Methods: A total of 844 E.

In-vitro mutagenesis of qnrA and qnrS genes and quinolone resistance in Escherichia coli [PDF]

Clinical Microbiology and Infection, 2007
Plasmid-mediated quinolone resistance is being reported increasingly worldwide among isolates of enterobacteria. This resistance is mostly associated with Qnr-like determinants that confer resistance to quinolones, e.g., nalidixic acid, and reduced susceptibility to fluoroquinolones. This study investigated whether amino-acid substitutions in QnrA1 and
