Synergism of LL-37 with other antimicrobial proteins in killing of various bacteria. The MIC for LL-37 was determined against a number of bacteria (two strains of E. coli, P. aeruginosa, E. faecalis, and S. aureus). The MICs were determined with or without the addition of medium E or the presence of lysozyme (500 μg/ml) and lactoferrin (1 mg/ml for all except S. aureus, which was 250 μg/ml). Pancreatic phospholipase A₂ (1.25 mg/ml) was used as negative control. This experiment was repeated on three occasions with essentially identical results.
