| Pseudomonas aeruginosa (clinical isolate) | 10±0.0 | 20±3.6 | 10±1.3 | 20±1.0 |
| Salmonella Typhimurium ATCC 14028 | 10±0.58 | 10±0.46 | 10±0.0 | 20±0.0 |
| Klebsiella pneumoniae ATCC 700603 | 10±0.0 | 10±1.73 | 5±0.0 | 20±0.0 |
| Shigella sonnei ATCC 25931 | 10±1.0 | 10±0.5 | 5±0.0 | 10±1.0 |
| Streptococcus bovis ATCC 49147 | 5±0.0 | 10±0.1 | 10±3.4 | 20±0.0 |
| Staphylococcus epidermidis ATCC 12228 | 5±0.0 | 10±0.5 | 10±0.7 | 10±0.0 |

Determination of MICs and MBCs for AgNPs was performed at least three times in duplicate. MIC, Minimal inhibitory concentration; MBC, Minimal bactericidal concentration.
