Figure 5.

Biofilm dispersion index (%) of MRSA ATCC 43300 (A) and 98825 TX (B) biofilms pre-grown with Er and Met I at 0, 2 and 5 mg/L and soaked in PBS for 1 h. Data report the mean ± standard deviation of three independent measurements. Different superscript letters indicate significant differences (Tukey’s HSD, p ≤ 0.05) between the means of different concentrations whereas a * indicates significant differences between Er and the corresponding counterpart grown with Met I at the same concentration.
