Prevalence of plasmid-mediated quinolone resistance genes and biofilm formation in different species of quinolone-resistant clinical Shigella isolates: a cross-sectional study [PDF]
European Journal of Medical ResearchBackground The purpose of this study was to look into the presence of plasmid-mediated quinolone resistance (PMQR) genes and biofilm formation in several species of clinical Shigella isolates that were resistant to quinolones.

Quinolone Resistance in Gallibacterium anatis Determined by Mutations in Quinolone Resistance-Determining Region. [PDF]
Antibiotics (Basel), 2023 Control of the important pathogen, Gallibacterium anatis, which causes salpingitis and peritonitis in poultry, relies on treatment using antimicrobial compounds. Among these, quinolones and fluoroquinolones have been used extensively, leading to a rise in the prevalence of resistant strains.

Mechanism of Quinolone Action and Resistance
Biochemistry, 2014 Quinolones are one of the most commonly prescribed classes of antibacterials in the world and are used to treat a variety of bacterial infections in humans. Because of the wide use (and overuse) of these drugs, the number of quinolone-resistant bacterial

Journal of Pure and Applied Microbiology, 2022 Klebsiella pneumoniae (K. pneumoniae) is an important pathogen associated with various infections. The emergence of antibiotic resistances, such as quinolone resistance and those due to extended-spectrum beta-lactamases (ESBL), reduces the available ...

Plasmid-Mediated Quinolone Resistance [PDF]
Microbiology Spectrum, 2014 ABSTRACTThree mechanisms for plasmid-mediated quinolone resistance (PMQR) have been discovered since 1998. Plasmid genesqnrA, qnrB, qnrC, qnrD, qnrS,andqnrVCcode for proteins of the pentapeptide repeat family that protects DNA gyrase and topoisomerase IV from quinolone inhibition.

Mechanisms of drug resistance: quinolone resistance [PDF]
Annals of the New York Academy of Sciences, 2015 Quinolone antimicrobials are synthetic and widely used in clinical medicine. Resistance emerged with clinical use and became common in some bacterial pathogens. Mechanisms of resistance include two categories of mutation and acquisition of resistance‐conferring genes.
