a
Sensititre results were not available for 3 strains.
b
The total number of strain-drug pairs is the number that was evaluated against Sensititre/Vitek 2 and excludes pairs that show intrinsic resistance (see Table 2 for details).
c
ESBL screen results are included in the CA calculations but not the EA.
