Ability of A. baumannii strains to adhere and to invade A549 cells. Quantitative analysis of the adherence of A. baumannii strains to A549 cells showed significant increases (p = 0.001) after 4 h of infection. Analysis of the invasion frequency showed a significant increase (p = 0.028) comparing the 433H strain and other clinical strains, including ATCC®19606TM. The data (CFU/mL) for the invasion frequency are presented as the means and standard deviations from at least three independent experiments conducted in triplicate. Represents a significant difference. The adherence data are presented as bars, and the invasion frequencies are black lines. A. baumannii ATCC®19606TM was used as a positive control.
