Orientin Enhances Colistin-Mediated Bacterial Lethality through Oxidative Stress Involvement

Table 1

Antibacterial activities of colistin and orientin and their friction inhibitory concentration index.

Test isolates	Zone of inhibition (mm)		MIC (μg/mL)		MBC (μg/mL)		FICI	Interactions
	Colistin	Orientin	Colistin	Orientin	Colistin	Orientin
K. pneumoniae	23	25	16	64	128	512	0.37	Synergistic
P. aeruginosa	18	11	64	256	256	1024	0.31	Synergistic

MIC: minimum inhibitory concentration, MBC: minimum bactericidal concentration, and FICI: friction inhibitory concentration index.
