Susceptibilities of encapsulated and unencapsulated meningococcal strains to CAMPs. (A to E) Susceptibilities of B1940 (black columns), the B1940 siaD(−C) mutant (gray columns), and the B1940 cps mutant (white columns) to different concentrations of polymyxin B (A), human defensins (β-defensin 1, β-defensin 2, defensin HNP-1, and defensin HNP-2) (B), porcine protegrin PG-1 (C), human cathelicidin LL-37 (D), and murine cathelicidin-related peptides CRAMP and CRAMP-18 (E). Values are means of three independent experiments made in triplicate with standard errors. Asterisks mark statistically significant differences in survival values between B1940 and the B1940 siaD(−C)/B1940 cps mutant (P value of <0.05).
