Two neutrophil defensins, rabbit peptides NP-1 and NP-5, were examined for their in vitro antibacterial activity against a panel of Gram-positive and Gram-negative organisms isolated from mastitic cows. Incubation for 60 minutes with 5 micrograms/ml of NP-1 in 10 mM sodium phosphate buffer resulted in substantial killing (greater than 95%) of all organisms tested. Although NP-5 was virtually inactive under these same conditions, supplementation of the incubation mixture with dilute nutrient media sensitized otherwise resistant organisms to this defensin. For both NP-1 and NP-5, bactericidal activity was dependent on time and concentration. Our findings demonstrate that the spectrum of defensin bactericidal activities include clinically important bovine pathogens. Further, the data demonstrate that NP-1 and NP-5, peptides which are homologous in 18 of their 33 residue positions, possess distinct mechanisms of action.
