Biofilm topology by scanning electron microscopy (magnification, ×8,000). Mature biofilms treated with BN (2 MIC) with or without VCM (2 MIC) and were cultivated at 37°C for 48 h. Biofilms were gold coated prior to analysis. Scale bars, 5 µm. BN, brazilin; VCM, vancomycin; MIC, minimum inhibitory concentration.
