Figure 3From: Potential novel therapeutic strategies in cystic fibrosis: antimicrobial and anti-biofilm activity of natural and designed α-helical peptides against Staphylococcus aureus, Pseudomonas aeruginosa, and Stenotrophomonas maltophiliaActivity of AMPs at bactericidal concentrations against preformed P. aeruginosa biofilms. BMAP-27, BMAP-28, P19(9/B), and Tobramycin were tested at 1x (white bars), 5x (gray bars), and 10xMIC (black bars) against preformed biofilm by 6 P. aeruginosa CF strains. Results are expressed as percentage of biofilm’ viability compared to control (not exposed, 100% viability). ** p < 0.0001, Fisher’s exact test.Back to article page
