| Sample | Inhibition Zone (mm) Staphylococcus aureus | Inhibition Zone (mm) Escherichia coli |
|---|---|---|
| PVA | - | - |
| CHI | - | - |
| PVA/AMP 0.3% | 2.34 ± 0.69 | - |
| PVA/AMP 1.0% | 3.54 ± 0.60 | 1.26 ± 0.05 |
| * CHI/AMP 0.3% | 3.26 ± 0.87 | - |
| * CHI/AMP 1.0% | 4.36 ± 0.35 | - |
| PVA/ADD/AMP 0.3% | - | 1.27 ± 0.17 |
| PVA/ADD/AMP 1.0% | 1.30 ± 0.17 | 1.13 ± 0.05 |
| * CHI/ADD/AMP 0.3% | 3.61 ± 0.31 | 1.16 ± 0.21 |
| * CHI/ADD/AMP 1.0% | 4.18 ± 0.21 | 1.10 ± 0.16 |
| * PVA/CHI/ADD/AMP 0.3% | 1.18 ± 0.04 | - |
| * PVA/CHI/ADD/AMP 1.0% | 1.20 ± 0.10 | - |
* ANOVA test showed that CHI was the unique component which its significance was higher than ρ < 0.05.
