Illustration of the biofilm eradication mechanism of PCN against MRSA isolates (n = 10). A and C The reduction in EPS production after PCN treatment at 1/2 and 1/4 MICs of PCN was determined by the phenol–sulfuric acid method. B The effect of PCN on bacterial viability within a pre-established MRSA biofilm shows a reduction in bacterial viability after treatment with 40 and 20 µg/ml of PCN. The error bars indicate standard deviations. The asterisks represent statistical significance (P < 0.05)
