mfsQ encoding an MFS efflux pump mediates adaptive protection of Stenotrophomonas maltophilia against benzalkonium chloride.

Abstract excerpt

The persistence of Stenotrophomonas maltophilia, especially in hospital environments where disinfectants are used intensively, is one of the important factors that allow this opportunistic pathogen to establish nosocomial infections. In the present study, we illustrated that S. maltophilia possesses adaptive resistance to the disinfectant benzalkonium chloride (BAC). This BAC adaptation was abolished in the ΔmfsQ...
