Table 3. Relationship between biofilm formation and the expression of efflux pumps and biofilm-related genes in A. baumannii in the presence of CST at its sub-MICs.

A. baumannii		Factor	adeB	adeG	adeJ	ompA	bap	pgaA	abaI
ATCC 19606		Biofilm formation	0.096	0.821**	−0.023	0.597**	0.935**	0.571*	0.905**
MDRA	R2		0.922**	0.624**	0.425	0.459	0.448	0.242	0.787**
	R3		0.726**	0.797**	0.842**	0.362	−0.060	0.855**	0.882**

Pearson correlation coefficients were calculated for ATCC19606, R2, and R3 strains cultured with different sub-MIC concentrations (0, 1/4, and 1/2 the MIC) of CST.

** Significant at the level of 0.01 (2-tailed).

* Significant at the level of 0.05 (2-tailed).
