Antibacterial activities of naturally occurring compounds against antibiotic-resistant Bacillus cereus vegetative cells and spores, Escherichia coli, and Staphylococcus aureus.

摘要: After demonstrating the lack of effectiveness standard antibiotics against acquired antibiotic resistance Bacillus cereus (NCTC 10989), Escherichia coli 1186), and Staphylococcus aureus (ATCC 12715), we showed that following natural substances were antibacterial these resistant pathogens: cinnamon oil, oregano thyme carvacrol, (S)-perillaldehyde, 3,4-dihydroxybenzoic acid (beta-resorcylic acid), 3,4-dihydroxyphenethylamine (dopamine). Exposure three pathogens to a dilution series test compounds oil was most active substance. The oils pure exhibited exceptional activity B. vegetative cells, with being at nanogram per milliliter levels. In contrast, activities spores very low. Activities in approximate order: > approximately carvacrol perillaldehyde dopamine beta-resorcylic acid. order susceptibilities inactivation as follows: (vegetative) >> S. E. (spores). Some may be effective antibiotic-resistant bacteria foods feeds.
