FIG. 5.

Adherence to epithelial cells (A) and entry into epithelial cells (B) and monocyte-derived macrophages (C) by L. pneumophila strains AA100, JR32, and Lp01 grown on BCYE agar plates (A to C) or in liquid media (B and C) to exponential (Exp) or post-exponential (PExp) phase. Adherence and entry by plate-grown strain AA100 were arbitrarily set to 100. Data points and error bars represent the means and standard deviations, respectively, of assays done in triplicate. Results shown are for a typical experiment.
