a
BP, breakpoint used to interpret MIC results; V2, Vitek 2 breakpoints; CLSI, M100S 26th edition breakpoints.
b
Total represents the number of isolates tested multiplied by the number of antimicrobials tested.
c
EA, essential agreement (MIC ±1 doubling dilution); CA, categorical agreement; VMEs, very major errors; MEs, major errors; mEs, minor errors.
