AMPs affect the bacterial membrane integrity. Scanning electron microscopy (SEM) images of bacterial strains treated with peptides pept_84 and pept_1545 and a positive control, melittin B. subtilis and E. coli were treated with peptides at a final concentration equal to 1/2× and 1× MIC for 8 h, and S. haemolyticus was treated with peptides at a final concentration equal to 1/2× and 1× MIC for 24 h. Scale bars: 2 μm.
