Inhibition Of Bacillus Anthracis And Potential Surrogate Bacilli Growth From Spore Inocula By Nisin And Other Antimicrobial Peptides
JOURNAL OF FOOD PROTECTION(2006)
摘要
The ability of nisin, synthetic temporin analogs, magainins, defensins, and cecropins to inhibit Bacillus anthracis, Bacillus cereus, Bacillus thuringiensis, Bacillus mycoides, and Bacillus subtilis growth from spore inocula was determined using well diffusion assays. Nisin, magainin II amide, and defensins were inhibitory in screening against B. anthracis Sterne or B. cereus ATCC 7004, but only nisin inhibited virulent B. anthracis strains. The MICs of nisin against the 10 Bacillus strains examined were 0.70 to 13.51 mu g/ml. Synthetic temporin analogs also inhibited B. anthracis but were not as potent as nisin. None of the strains examined were appropriate B. anthracis surrogates for testing sensitivity to antimicrobial peptides.
