Shiga toxin Stx2 production is promoted by enrofloxacin in experimental in vitro-selected mutants of Escherichia coli O157:H7 resistant to fluoroquinolones.

Foodborne pathogens and disease - 1 Mar 2009

Maurer Claire, Meunier Daniele, Madec Jean-Yves

Abstract excerpt

Enrofloxacin-resistant mutants of Stx2-producing Escherichia coli O157:H7 from cattle were selected. Mutants produced threefold higher Stx2 levels than native strains after induction with enrofloxacin. Mutants were also inducible using hundredfold higher enrofloxacin concentrations than the ones...
