Fig. 6

Scanning electron microscopy images of Staphylococcus epidermidis in the presence or absence of pseudonajide. Bacterial cells were cultured with or without 25 μM pseudonajide (peptide 2) for 1, 4, and 24 h. Plastic slides were placed inside the culture well plates and used to analyze biofilm and cell morphology. White arrows indicate the cells with different morphologies at 4 and 24 h in the presence of pseudonajide. Images are shown at 500 and 10,000x magnification, and were obtained using a JEOL JSM-7100F scanning electron microscope
