Scanning electronic microscope (SEM) high-resolution images of E. coli ATCC 25922 in the presence of BotrAMP14 (8.1 μM) and CrotAMP14 (2.2 μM) peptides after 0 min (A,B), 5 min (C,D), 30 min (E,F) and 60 min (G,H) of incubations. Arrows indicate cell damage. Panels A, C, E, and G represent the treatments with BotrAMP14. Panels B, D, F, and H represent the treatments with CrotAMP14 peptide.
