	Breakpoint1) (µg/mL)	MIC range (µg/mL)	MIC50 (µg/mL)	MIC90 (µg/mL)	% susceptible
Cefepime	32	0.25 to 128	32	64	60.00
Imipenem	8	0.25 to > 128	16	64	35.00

According to the M100–S23 guideline (CLSI).
MIC, minimum inhibitory concentration (µg/mL); MIC50, MIC value at which growth of 50% of isolates was inhibited; MIC90, MIC value at which growth of 90% of isolates was inhibited.
