Enhanced antibacterial effect of antibiotics in the presence of AgNPs. All test strains were treated for 4 h with sublethal concentrations of ampicillin or AgNPs, or combinations of AgNPs and ampicillin (A) or combinations of AgNPs and vancomycin (B). All test strains were treated for 4 h with sublethal concentrations of vancomycin or AgNPs, or combinations of AgNPs and vancomycin. Bacterial survival was determined at 4 h by the CFU assay. The results are expressed as the means ± SD of three separate experiments, each of which contained three replicates. Treated groups showed statistically significant differences from the control group by the Student's t test (p < 0.05).
