Effect of human serum albumin (HSA) and pooled normal human serum (HS) on the expression of antibiotic resistance genes of A. baumannii strains. qRT-PCR of AMA16: (A) AB0057 (B) and ABUH702 (C) strains genes associated with antibiotic resistance expressed in LB, LB supplemented with 3.5% HSA, or in HS. Fold changes were calculated using double ΔΔCt analysis. At least three independent samples were used. LB was used as the reference condition. Statistical significance (p < 0.05) was determined by ANOVA followed by Tukey’s multiple-comparison test, one asterisks: * p < 0.05; two asterisks: ** p < 0.01; and three asterisks: *** p < 0.001.
