The changing pattern of antimicrobial resistance within 42 033 <i>Escherichia coli</i> isolates from nosocomial, community and urology patient‐specific urinary tract infections, Dublin, 1999–2009

Abstract

E. coli remains the commonest infecting uropathogen in the community and hospital setting with its incidence climbing from 50 to 60% of UTIs over the 11-year period. Neither penicillins nor trimethoprim represent suitable empirical antimicrobials for UTI and ciprofloxacin resistance in this Dublin-based study renders it unsuitable empirical therapy for nosocomial UTIs and UTIs in the urology population. The dramatic 11-year rate increase in gentamicin resistance is of paramount concern.
