Adherence to A549, hydrophobicity, and biofilm formation assays results for clinical isolates of Acinetobacter baumannii. (A) A549 monolayer cells (105 cell/mL) were incubated with A. baumannii isolates (106 CFU/mL) for 3 h. ABI038 isolate was significantly more adherent than other isolates and A. baumannii ATCC19606 (control strain). (B) Cell surface hydrophobicity of isolates was measured using Microbial Adhesion to Hydrocarbon. Adherence to p-xylene by ABI022 isolate was significantly different the adherence by other clinical isolate and control strain. (C) Quantitative analysis of biofilm formation by A. baumannii isolates was determined by a microtiter-plate assay. The clinical ABI022 formed a higher biofilm in comparison with other clinical isolates (p < 0.01, p < 0.001) and A. baumannii ATCC19606 (p < 0.05). Data are shown as mean ± SD and statistical differences determined by one-way ANOVA and Dunnett's correction (***p < 0.001, **p < 0.01, * p < 0.05).
