A Novel Insight into Dehydroleucodine Mediated Attenuation of Pseudomonas aeruginosa Virulence Mechanism

Table 3

FICa: MIC of the combination/MICa alone. FICb: MIC of the combination/MICb alone. FICI: FICa + FICb. FICI interpretation: synergistic effect when FICI ≤ 0.5, additive effect when 1 > FICI < 0.5, and antagonistic effect when FICI > 1.

Microorganism	MIC (μg/mL) Chloramphenicol	FICa	FICb	FICI	Effect
