Antimicrobial activity of AvBD-6 and AvBD-12 against E. coli, S. Typhimurium and S. aureus. Bacteria (105 CFU/ml) were incubated with various concentrations of AvBD-6 or AvBD-12 in the presence of 5 mM NaCl (■), 50 mM NaCl (▲), or 150 mM () at 37 °C for 3 h. a Antimicrobial activities of AvBD-6. b Antimicrobial activities of AvBD-12. Antimicrobial activity was presented as percent of killing as compared to no-AvBD control. Data are means of three independent experiments ± SD (n = 3). Asterisks indicate statistically significant difference between 5 mM and 50 mM and 150 mM of NaCl (*p < 0.05, **p < 0.01)
