Decreased fluoroquinolone susceptibility in mutants of Salmonella serovars other than Typhimurium: detection of novel mutations involved in modulated expression of ramA and soxS.

Abstract excerpt

OBJECTIVES: Mutants of five Salmonella enterica serovars were investigated for structural changes in regulatory regions known to be involved in the up-regulation of efflux pumps. METHODS: Five Salmonella field isolates and mutants, in which efflux pump inhibitor tests previously pointed towards a...
