Fig. 1From: Antibacterial, antibiofilm, and anti-quorum sensing activities of pyocyanin against methicillin-resistant Staphylococcus aureus: in vitro and in vivo studyA The corresponding zone of inhibition produced by PCN (2, 3, and 4) around wells against MRSA at a concentration of 40 µg/ml, SDW was a negative control (1). B The dose-dependent antibacterial activity produced by PCN against MRSA isolates at concentrations of 40, 20, and 10 µg/ml. The error bars indicate standard deviations. The asterisks represent statistical significance (P < 0.05)Back to article page
