Antimicrobial activity of two bactenecins against spirochetes

Infect Immun. 1993 Jul;61(7):3081-3. doi: 10.1128/iai.61.7.3081-3083.1993.

Abstract

Bac5 and Bac7 are antimicrobial peptides of bovine neutrophils that act on enteric gram-negative bacteria. We report here that these two peptides immobilize and kill Leptospira interrogans and Leptospira biflexa with MBCs of 6 to 25 micrograms/ml. Conversely, although both peptides bind to Borrelia burgdorferi, the organism is resistant to their action.
