Susceptibility testing of urinary isolates of Escherichia coli to mecillinam using NCCLS methodology.

Criteria for susceptibility testing of mecillinam against 533 isolates of Escherichia coli and a further 309 Enterobacteriaceae, according to NCCLS methodology, were determined. Correlation of MIC to inhibition zones was good for all species. For urinary isolates of E.

Cross-resistance and associated resistance in 2478 Escherichia coli isolates from the Pan-European ECO.SENS Project surveying the antimicrobial susceptibility of pathogens from uncomplicated urinary tract infections.

The antimicrobial resistance profiles, comprising 12 antibiotics, of 2478 isolates of Escherichia coli from the ECO.SENS Project involving women with acute uncomplicated urinary tract infection at 252 community health care centres in 17 countries were determined. Resistance to ampicillin alone (6.
