EUCAST: European Committee on Antimicrobial Susceptibility Testing; ECOFFs: epidemiological cut‐off values; NA: not available.
a
EUCAST epidemiological cut‐off values as laid down in the Decision 2013/652/EU. For some antimicrobials these values have been updated (see below).
b
For cefepime, the cut‐off value used in the analysis for Salmonella was > 0.125 mg/L.
c
For temocillin, the cut‐off value used in the analysis was > 32 mg/L.
