MPX inhibits biofilm formation. (A) The results of crystal violet staining of biofilms after different concentrations of MPX were applied to S. aureus ATCC 25923. (B) OD570 measurement after crystal violet was dissolved in 70% ethanol. (C) After exposure of S. aureus ATCC 25923 to different concentrations of MPX, scanning electron microscopy was used to observe the biofilm. (D) The results of staining S. aureus with SYTO 9/propidium iodide. Error bars indicate the mean ± SEM, n = 3. Statistical significance was defined as follows: **p < 0.01; ***P < 0.001; ns P > 0.05.
