(A) Inactivation of wild type (black bar), gra RS mutant (white bar) and complemented mutant (grey bar) by LL-37 after 20-min incubation with 20 μg/ml LL-37. (B) Inactivation of wild-type (squares) and mutant bacteria (circles) by human neutrophils after 15, 30 and 60 minutes. The means and SEM of three independent experiments run in duplicate (A) and the means and SD of two independent experiments run in duplicate (B) are shown. P values < 0.05 as calculated by Student's t test were regarded statistically significant.
