Amikacin	≤16	32	≥64
Tobramycin	≤2	4	≥8
Tigecycline	≤4		>4
Minocycline	≤1	2–4	≥8

Abbreviation MIC minimal inhibitory concentration

^aBreakpoints of each drug, except for tigecycline, are based on the Clinical and Laboratory Standards Institute recommendations. Breakpoints for tigecycline were based on those proposed by Petrini [17]
