WTA-glycosylation promotes Lm resistance against antimicrobial peptides (AMPs). Quantification of viable Lm strains, (A) Sv1/2a and (C) Sv4b, after incubation of the exponential-phase Lm strains with the antimicrobial peptides cathelicidin-related antimicrobial peptide (CRAMP) and LL-37 (10 μg/mL). Values from the AMP-treated samples were normalized to untreated controls (set at 100). Data represent mean ± SD of at least three independent experiments. Bacterial growth curves of Lm strains (B) Sv1/2a and (D) Sv4b grown in the presence of CRAMP and LL-37 (10 μg/mL). Data represent mean ± SD of three independent experiments (* p < 0.05; ** p < 0.01; *** p < 0.001; **** p < 0.0001).
