Enhanced effect of antibiotics and AgNPs on ROS generation. All test strains were treated with sublethal concentrations of antibiotics or AgNPs, or combinations of AgNPs with antibiotics for 12 h. ROS generation was measured by the XTT 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).
