Figure 4. Effects of AgNPs and/or co-treatment with ascorbic acid (AA) on bacterial isolates total thiol (A and B), superoxide dismutase (SOD) (C and D), and total antioxidant capacity (TAC) (E and F). Data are presented as mean of duplicates ± standard error mean (SEM). α is significant at p<0.05, and β at p<0.01 versus control and/or AgNPs 1x MIC (total thiol in S. aureus - B), ɣ at p<0.0001 versus control and/or AgNPs 3x MIC (total thiol in S. aureus - B).
