FIG 3 .

Percent fold changes of surface coverage of PA14 flagellar (A), type IV pilus (B), and quorum-sensing (C) mutants compared to PA14 WT on MSCFM–0.4% mucin–0.3% agar. Motility zones were measured after incubation at 37°C for 13 h. Results shown are means ± standard deviations (SD) for at least three independent experiments, with duplicates for each experiment. Asterisks indicate a statistically significant difference (P ≤ 0.05) between the mutants and WT as determined by Student’s t test.
