[Increasing prevalence of fosfomycin resistance in extended-spectrum-beta-lactamase-producing Escherichia coli urinary isolates (2005-2009-2011)].

Abstract

From 2005 our institution had an increasing prevalence of ESBL-producing E. coli rising to 8.7% in 2011. Carbapenems are still the most active agents. The increase of resistance was significant for fosfomycin.
