FIG. 4.

Flagellum-mediated motility and B. cenocepacia biofilm formation. (A) Each panel shows an image of a bacterial colony grown at 37°C for 24 h on medium solidified with 0.3% agar. (B) Electron micrograph of the fliC, ΔrpoN fliC, and ΔmotA mutants. Representative bacterial cells are shown. Bars correspond to 0.5 μm. (C) Quantitative comparison of biofilms formed by wild-type strain K56-2 and the fliC, ΔrpoN fliC, and ΔmotA mutants under static conditions. Each experiment was performed at least three times in triplicate. Error bars represent the standard error of the mean.
