Figure 1.
Effect of (A) 5-fluorocytosine (5-FC) and (B) 5-fluorouracil (5-FU) (0–1,000 μM) on P. aeruginosa PAO1 growth (left panels) and relative pyoverdine production (right panels) after 14-h growth at 37°C in the iron-poor complex medium TSBD. Values represent the mean (±SD) of six independent assays. Asterisks indicate statistically significant differences with respect to the untreated control (*P < 0.05, **P < 0.01, ***P < 0.001; ANOVA).
