Bactericidal assays of the Kn2-7 and BmKn2 peptides against S. aureus and E. coli AB94012.

Set point indicates untreated bacteria, and 0 minutes was defined as the time of the first sample collection, which was immediately after mixing bacteria and Kn2-7 or BmKn2. The other samples were collected at 5 min, 15 min, 30 min or 60 min. All of the counts were the average of three dishes, and the experiment was repeated at least three times. (A) Time-killing curve of Kn2-7 against S. aureus AB94004. (B) Time-killing curve of BmKn2 against S. aureus AB94004. (C) Time-killing curve of Kn2-7 against E. coli AB94012.
