L-lysine treatment affects the cell permeability of bacteria. (A–C). Pretreatment of A. baumannii 19606 with 20 mM L-lysine for 3 h accelerated antibiotic killing of 25 μg/ml Gen (A), 30 μg/ml Kan (B), or 20 μg/ml Ami (C). (D–F) L-lysine increased the cell permeability of A. baumannii 19606 (D), E. coli ATCC 25922 (E) and K. pneumoniae ATCC700603 (F).
