AFM and FEG-SEM visualization of the effect of temporins-SH on P. aeruginosa bacteria (A–C) and parasites (L. infantum promastigotes and T. cruzi epimastigotes; D–I). A–C, AFM imaging of P. aeruginosa: A, untreated control bacteria; B, bacteria after 1 h incubation with 50 μM SHa; C, bacteria treated for 1 h with 6 μM [K3]SHa. Bacteria were severely damaged by temporins compared to the control. D–G, AFM imaging of L. infantum promastigotes and T. cruzi epimastigotes: D and E, L. infantum untreated (D) or treated with 5 μM [K3]SHa (E); F and G, T. cruzi without peptide (F) or with 5 μM [K3]SHa (G). H and I, FEG-SEM visualization of L. infantum promastigotes without peptide (H) or with 5 μM [K3]SHa. Morphological changes were observed for parasites that were incubated with peptides (E, G and I).
