Membranolytic activity of the bNK2A peptide against M. paratuberculosis. (A) MAP control (× 4800, scale bar = 2 µm); (B) MAP with 100 µM bNK2A (cell debris is indicated by black arrows; × 4800, scale bar = 2 µm); (C) MAP control (× 68 000, scale bar = 200 nm); (D) MAP with 100 µM bNK2A (intracellular content leakage is indicated by white arrows; × 68 000, scale bar = 200 nm); (E) MAP with 100 µM bNK2A (intracellular content leakage is indicated by a white arrow; × 98 000, scale bar = 100 nm); (F) MAP with 100 µM bNK2A (ghost cell is indicated by a white arrow; × 68 000, scale bar = 200 nm).
