First detection of plasmid-mediated quinolone resistance in the community setting and in hospitalized patients in Switzerland.

Correlation of quinolone-resistance, qnr genes and integron carriage in multidrug-resistant community isolates of Klebsiella spp.

Objective(s): Plasmid-mediated quinolone resistance (PMQR) determinants and integrons have a considerable contribution to bacterial drug resistance in Gram-negative pathogens. We studied the prevalence of PMQR genes and integron carriage in multidrug-resistant community isolates of Klebsiella spp.Materials and Methods: Two hundred and fi...

The Emergence of Qnr-resistance Among Klebsiella pneumoniae spp in Zahedan

Objective: Although quinolone resistance results mostly from chromosomal mutations in Klebsiella pneumoniae, it may also be mediated by plasmid – encoded qnr determinants. Plasmid-mediated quinolone resistance (PMQR) was increasingly identified in Enterobacteriaceae family worldwide. The aim of this study was to investigate the prevalence of qnr genes in clinical isolates of Klebsiella pn...

Prevalence of Plasmid-Mediated Quinolones Resistance among Klebsiella pneumoniae Strains Isolated from Hospitals in Borujerd, Iran

ABSTRACT        Background and Objective: Klebsiella pneumoniae is one of the most common causes of bacterial infections. Presence of plasmid-mediated quinolone resistance genes causes low level of resistance in K. pneumoniae. This study investigated the prevalence of resistance to quinolones and fluoroquinolones, and the frequency of qnrA, qnrB and qnrS genes amo...

PCR Detection of Plasmid Mediated TEM, SHV and AmpC β-Lactamases in Community and Nosocomial Urinary Isolates of Escherichia coli

The main purpose of this study was the pattern of antibiotic resistance and the frequency of plasmid-dependent quinolone resistance (qnr) genes in Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae isolates isolated from surgical site

Introduction: In recent years, antibiotic resistance has been on the rise, leading to limited ways to control nosocomial infections (especially surgical site infections) and the right treatment options. The main purpose of this study was the pattern of antibiotic resistance and the frequency of plasmid-dependent quinolone resistance (qnr) genes in Pseudomonas aeruginosa, Escherichia coli and Kl...

High prevalence of plasmid-mediated quinolone resistance determinants in commensal members of the Enterobacteriaceae in Ho Chi Minh City, Vietnam

Antimicrobial-resistant pathogenic members of the Enterobacteriaceae are a well-defined global problem. We hypothesized that one of the main reservoirs of dissemination of antimicrobial resistance genes in Vietnam is non-pathogenic intestinal flora, and sought to isolate antimicrobial-resistant organisms from hospitalized patients and non-hospitalized healthy individuals in Ho Chi Minh City.
