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

Figure 1

Biofilm production by six (a–f) isolates of S. aureus in tryptone soy broth (TSB) added of subinhibitory concentrations of diclofenac. The horizontal dashed line indicates the cutoff value that separates production from nonproduction of the biofilm. Assays were repeated three times with similar results, and error bars represent mean with range. (a) A108. (b) A112. (c) A139. (d) B103. (e) B105. (f) B121.
