摘要
Quinolones are among the drugs of choice in the management of cholera caused by Vibrio cholerae. In this study, we demonstrate that, in addition to mutations detected in the target genes gyrA and parC, proton motive force-dependent efflux is involved in quinolone resistance in clinical isolates of V. cholerae.
