Figure 3

Effect of 5-fluorocytosine (5-FC) and 5-fluorouracil (5-FU) (0–1,000 μM) on growth and relative pyoverdine production (upper and lower panel, respectively) of P. aeruginosa PAO1 and five isogenic spontaneous mutants resistant to 5-FU (R1–R5) cultured in TSBD for 14 h in microtiter plates at 37°C. Values represent the mean (±SD) of three independent experiments. Asterisks indicate statistically significant differences with respect to the corresponding untreated control (*P < 0.05, ***P < 0.001; ANOVA).
