The Prevalence of Fluoroquinolone Resistance Mechanisms in Colonizing Escherichia coli Isolates Recovered from Hospitalized Patients

Abstract excerpt

BACKGROUND: Fluoroquinolones are the most commonly prescribed antimicrobials. The epidemiology of fecal colonization with Escherichia coli demonstrating reduced susceptibility to fluoroquinolones remains unclear. METHODS: During a 3-year period (15 September 2004 through 19 October 2007), all patients hospitalized for >3 days were approached for fecal sampling. All E. coli isolates with reduced susceptibility to...
