Figure 9: Bacterial adhesion to lung cells, (A) bacteria were pretreated with different concentrations of F/L-NAC, and then were added to A549 monolayers. Columns present the CFU counts when bacteria were treated. (B) A549 cells were treated with different concentrations of F/L-NAC and then bacteria were added to the cells. Columns here present the CFU counts when cells were treated. Data are the mean ± S.E.M. of three independent studies. P values were considered significant when compared to control *** P<0.001, ** P<0.01, * P<0.05. All experiments were repeated 3 times.
