Fig. 2From: Antibacterial, antibiofilm, and anti-quorum sensing activities of pyocyanin against methicillin-resistant Staphylococcus aureus: in vitro and in vivo studyConcentration-dependent eradication of MRSA strains (n = 10) pre-established biofilms after PCN treatment using the crystal violet assay. A The corresponding crystal violet-stained biofilm of MRSA after PCN treatment at different concentrations in a microtiter plate. B Micrographs of the disrupted biofilm of MRSA after PCN treatment at different concentrations on the glass surface by LM. C The scatter plot indicates the percentage of reduction in biofilm mass of MRSA strains after PCN treatment at concentrations of 40, 20, and 10 µg/ml. SDW served as a negative control. The error bars indicate standard deviations. The asterisks represent statistical significance (P < 0.05)Back to article page
