Figure 1.

Antimicrobial peptides exert activity against vegetative bacilli and endospores. B. anthracis Sterne bacilli (A, B) or spores (C, D) were incubated for 3 h with a range of the log10 peptide concentrations in 10 mM phosphate buffer and percent (%) survival was determined (EC50). Standard deviations of the mean are shown on each graph as error bars.
