TABLE 1.

Minimum inhibitory concentration (MIC), fractional inhibitory concentration (FIC), and FIC indices of linalool and meropenem against KPC-KP cells.

Combinations of linalool and meropenem (μg/ml)	KPC-KP				Type of interaction
	MICO	FIC	FICI	FICIc
Linalool	11,250	5,625	0.50	1.00	Additive
Meropenem	32.00	16.00	0.50

MIC_O, MIC of one component alone; FIC, MIC of one component in the most effective combination; FICI, FIC index of one component in the most effective combination; FICIc, total FICI of the combination of both components. FICIc ≤ 0.5, synergistic; FICIc > 0.5–4.0, additive; FICIc > 4.0, antagonistic.
