Minimal effective concentrations obtained by a radial diffusion assay for LL-37, fragments 106 and 110, the 18-mer LLKKK, and BMAP-27 for gram-negative and -positive bacteria and C. albicans^a

Pathogen	NaCl concn (mM)	Minimal effective concn (μM)
		LL-37	Fr 106	Fr 110	18-mer	BMAP-27
E. coli	0	0.26	0.40	0.33	0.33	0.14
	150	1.2	0.42	0.47	0.66	0.50
P. aeruginosa	0	0.18	0.26	0.18	0.29	0.20
	150	0.19	0.22	0.15	0.06	0.10
S. aureus	0	1.5	0.86	0.8	1.2	0.67
	150	4.6	2.6	2.4	0.39	0.45
C. albicans	0	10	5.1	2.4	2.2	0.36
	150	>40	>40	>40	>40	>40

^aThe values were determined at a low (0 mM) or physiological (150 mM) concentration of NaCl. Each value is based on data from three independent experiments.
