Characterization of Ciprofloxacin Resistance in Laboratory-Derived Mutants of Vibrio parahaemolyticus with qnr Gene

Foodborne Pathogens and Disease, 2018
Ciprofloxacin, a broad-spectrum fluoroquinolone, is a bactericidal antibiotic targeting DNA gyrase and DNA topoisomerase IV encoded by the gyrA and parC genes. Resistance to fluoroquinolones requires the accumulation of multiple mutations including those

Quinolone-resistant uropathogenic E. coli: is there a relation between qnr genes, gyrA gene target site mutation and biofilm formation?

Journal of Medical Microbiology, 2021
Introduction. The resistance to quinolone reported in uropathogenic Escherichia coli (UPEC) is commonly caused by mutations in the target site encoding genes such as the gyrA gene.

Evolution and Recombination of the Plasmidic qnr Alleles

Journal of Molecular Evolution, 2008
qnr is an important and recently emerged plasmidic fluoroquinolone resistance gene. Numerous qnr alleles have been detected, but previous studies have suggested that there is little functional divergence among them. We performed phylogenetic analysis of representative qnr alleles and examined the phylogeny for the occurrence of positive selection (d(N)/
