Mechanism of plasmid-mediated quinolone resistance [PDF]
Proceedings of the National Academy of Sciences, 2002 Quinolones are potent antibacterial agents that specifically target bacterial DNA gyrase and topoisomerase IV. Widespread use of these agents has contributed to the rise of bacterial quinolone resistance. Previous studies have shown that quinolone resistance arises by mutations in chromosomal genes.

Quinolone Resistance Genes and Their Contribution to Resistance in Vibrio cholerae Serogroup O139
Antibiotics, 2023 Background. Quinolones are commonly used for reducing the duration of diarrhea, infection severity, and limiting further transmission of disease related to Vibrio cholerae, but V. cholerae susceptibility to quinolone decreases over time.

Prevalence of Plasmid-Mediated Quinolone Resistance [PDF]
Antimicrobial Agents and Chemotherapy, 2003 ABSTRACT Quinolone resistance encoded by the qnr gene and mediated by plasmid pMG252 was discovered in a clinical strain of Klebsiella pneumoniae that was isolated in 1994 at the University of Alabama at Birmingham Medical Center.

Plasmid-Mediated Quinolone Resistance: a Multifaceted Threat [PDF]
Clinical Microbiology Reviews, 2009 SUMMARYAlthough plasmid-mediated quinolone resistance (PMQR) was thought not to exist before its discovery in 1998, the past decade has seen an explosion of research characterizing this phenomenon. The best-described form of PMQR is determined by theqnrgroup of genes.

OCCURRENCE OF QUINOLONE RESISTANCE GENES AMONG SALMONELLA SPECIES ISOLATED FROM CHICKENS [PDF]
Kafrelsheikh Veterinary Medical Journal, 2015 Resistance to antimicrobial agents within nontyphoidal Salmonella serotypes is considered a serious problem worldwide so this study was aimed to investigate the wide spread Plasmid-mediated quinolone resistance between different Salmonellae isolated from

Emergence of plasmid-mediated resistance to quinolones in Enterobacteriaceae [PDF]
Journal of Antimicrobial Chemotherapy, 2005 Although quinolone resistance results mostly from chromosomal mutations in Enterobacteriaceae, it may also be mediated by plasmid-encoded Qnr determinants. Qnr proteins protect DNA from quinolone binding and compromise the efficacy of quinolones such as nalidixic acid.

Microorganisms, 2020 Plasmid-mediated quinolone resistance (PMQR) remains one of the main mechanisms of bacterial quinolone resistance and plays an important role in the transmission of antibiotic resistance genes (ARGs). In this study, two novel plasmids, p3M-2A and p3M-2B,

Mechanisms of quinolone resistance and implications for human and animal health [PDF]
Veterinarski Glasnik, 2010 Quinolone antibiotics have been widely used in human and veterinary medicine. This has caused the development of resistance and difficulties in the treatment of complicated bacterial infections in humans.
