Figure 9

Enhancement of antibacterial activity of antibiotic in the presence of AgNPs. Antibacterial activities were determined by the agar diffusion method. The MICs of AgNPs for each test strain were loaded into the wells formed on plates containing a bacterial lawn. Growth inhibition was determined by measuring the zone of inhibition after 24 h. Experiments were performed in triplicate. The percentage of enhanced antibacterial activity was calculated using the formula (B - A/A) × 100. The results are expressed as the means ± SD of three separate experiments. Treated groups showed statistically significant differences from the control group by the Student's t test (p < 0.05).
