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.

Plasmid-mediated Quinolone Resistance among Non-TyphiSalmonella enterica Isolates, USA
Emerging Infectious Diseases, 2010 We determined the prevalence of plasmid-mediated quinolone resistance mechanisms among non-Typhi Salmonella spp. isolated from humans, food animals, and retail meat in the United States in 2007. Six isolates collected from humans harbored aac(6′)Ib-cr or

A mutational analysis and molecular dynamics simulation of quinolone resistance proteins QnrA1 and QnrC from Proteus mirabilis [PDF]
, 2010 Background The first report on the transferable, plasmid-mediated quinolone-resistance determinant qnrA1 was in 1998. Since then, qnr alleles have been discovered worldwide in clinical strains of Gram-negative bacilli.
