Objectives: To assess ciprofloxacin resistance among Escherichia coli isolates from bacteraemia patients in England in relation to age, sex and Region.

Methods: Routine susceptibility data for bacteraemia isolates were collected from over 90% of hospitals in England.

Results: During 1995–2001, the prevalence of ciprofloxacin resistance trebled, from 2.1% to 6.5%. Isolates from men were more frequently resistant than those from women, possibly because infections in men more often involve nosocomial strains. Resistance was rare (<1.5%) in isolates from patients aged <1 year; among older patients, resistance was unrelated to age in isolates from women, but peaked in the 15–44 age group for men.

Conclusions: The prevalence of ciprofloxacin resistance in E. coli from bacteraemia is strongly associated with sex and, to a lesser extent, age.

Keywords: Keywords: E. coli, bacteraemia, gender, ciprofloxacin resistance
