Abstract excerpt

BACKGROUND: Fluoroquinolone (FQ) resistance is increasing worldwide among Salmonella species. Among the mechanisms involved, increased efflux via the tripartite AcrAB-TolC efflux system is mainly modulated through control of expression via the ramRA regulatory locus gene products. Interestingly, in some reference strains these have also been experimentally shown to regulate cell invasion-related genes of the type...
