Figure 3. oprF biofilm defect in TSB is independent of PQS.

24-hour static microtiter biofilm assays were performed in TSB with PAO1 (black), ∆pslD (blue), ∆pqsA (stripes), ∆pqsH (dots), ∆oprF (red), ∆oprF∆pqsA (stripes with red outline), and ∆oprF∆pqsH (dots with red outline). Biofilm formation is normalized to WT. Error bars, SEM (N = 3); letters, statistical groupings (p < 0.01; one-way ANOVA with post hoc Tukey HSD).
