Figure 2. SCWDs differ in their antibacterial effect.

Antibacterial effect of SCWDs against (A) E. coli and (B) S. aureus. Gentamicin was used as a positive control, and gauze only was used as a negative control. Scatter dot plot with zone of inhibition given in cm². Ten replicates (n=10) were performed for each SCWD. Statistical analysis was performed using ordinary one-way ANOVA with Tukey’s multiple comparisons test. Error bars = mean ± SD. Mean is represented as a red line. **p<0.01, ***p<0.001, and ****p<0.0001. ns: not significant, SCWD: silver-containing wound dressing, E. coli: Escherichia coli, S. aureus: Staphylococcus aureus.
