Multicenter Study
Antimicrobial susceptibility of clinical Escherichia coli isolates from uncomplicated cystitis in women over a 1-year period in Spain.
High usage of antibiotics in Spain has led to an increase in resistance in urinary Escherichia coli isolates in different geographic regions. The problem of resistance in urinary E. coli in Spain was investigated by gathering a large number of isolates from 20 different sites nationwide over a 1-year period from November 2003 to October 2004 in a large population of women. The objectives of this study were to assess the resistance to the antibiotics most commonly prescribed for community-acquired urinary tract infections (UTIs), according to age and different geographical areas of Spain, and to evaluate the potential association between geographical differences in quinolone consumption and resistance to E. coli. ⋯ Fosfomycin, amoxicillin/clavulanic acid and cefuroxime-axetil are the most suitable antibiotics for empirical treatment in Spain given the high 18% and 26% resistance rates to quinolones and cotrimoxazole, respectively. Higher resistance rates to ciprofloxacin were associated with being aged 65 years and over. These data need to be considered when recommending empirical therapy for acute cystitis.
