Diclofenac May Induce PIA-Independent Biofilm Formation in Staphylococcus aureus Strains

Figure 4

Scanning electron microscopy images of three strains of S. aureus. Bacteria were grown in twenty-four well tissue culture plates with Thermanox plastic coverslips at 35°C for 24 h. (a, b, and c) SA139, SA150, and B103 strains, respectively, grown in medium without diclofenac (magnification: 4000x); (d, e, and f) SA139, SA150, and B103 strains, respectively, grown in medium with diclofenac (magnification: 4000x); and (g, h, and i) images of the respective strains grown in medium with diclofenac (magnification: 40000x). Scale bars: (A, B, C, D, and F) = 10 μm; (G, H, and I) = 1 μm.
