Table 3.
Antimicrobial susceptibility values for all E. coli isolates. The MICs were determined by broth microdilution and interpreted using ECOFF cut-off values (in columns) in μg ml−1 and show the numbers of isolates (in rows) with MIC above these values for each antimicrobial tested. Full description of the each antimicrobial is given in Methods
