Mounting resistance in Enterobacteriaceae, such as 11 Escherichia coli and Klebsiella pneumoniae, complicates the treatment of common community-acquired infections. Although third-generation cephalo sporin resistance in E coli is still below 5% in many European countries, it has increased substantially in others, exceeding 25% and even reaching 50% in bacteria isolated from invasive infections in the European 3 Antimicrobial Resistance network.
