Abstract
Urinary tract infections (UTIs) are prevalent worldwide, particularly among women. Their incidence increases with age, and treatment is increasingly challenging owing to antibiotic resistance and the lack of new agents. We investigated the susceptibility of current urinary isolates to fosfomycin and other antibiotics across Europe. This cross-sectional study collected consecutive urinary isolates from non-hospitalised women at 20 centres in Belgium, the UK, Italy, Spain and Russia. Bacteria were tested by disk diffusion with relevant antibiotics. As a quality control, a central laboratory re-tested, by agar dilution, (i) isolates found resistant to fosfomycin and (ii) every tenth isolate; all non-Russian sites were included. A total of 2848 isolates were analysed, principally Escherichia coli (2064; 72.5%), Klebsiella spp. (275; 9.7%) and Proteus spp. (103; 3.6%). For E. coli, agents active against >90% of isolates were nitrofurantoin (98.5%), fosfomycin (96.4%) and mecillinam (91.8%). Fosfomycin and nitrofurantoin remained active against >90% of cephalosporin-resistant E. coli. Among 143 E. coli recorded as susceptible locally by disk tests, 138 (96.5%) were confirmed susceptible by minimum inhibitory concentration (MIC) tests, however resistance was only confirmed in 29/58 (50.0%) of those reported resistant by local disk tests. Escherichia coli was found to be the most common uropathogen isolated and was highly susceptible to fosfomycin, nitrofurantoin and mecillinam, all used effectively for more than 30 years. Guidelines advocating fosfomycin for uncomplicated UTIs in women remain microbiologically valid.
