Figure 3:

Effects on C. albicans biofilm viability, as assessed by the XTT assay, of treatment with different combinations (+ with, − without) of green diode laser (532 nm), erythrosine (ERY) and synthetic killer decapeptide (KP). Results are expressed as mean values and standard deviation (SD) of the optical density (OD) at 490 nm. Data were analysed by one-way ANOVA and Tukey post hoc test. **p < 0.01, ****p < 0.0001, significant difference vs control (no treatment); bars with the same letter represent no significant difference. Data reported are from one representative experiment out of three experiments with comparable results.
