Inhibition of listeriolysin O and phosphatidylcholine-specific production in Listeria monocytogenes by subinhibitory concentrations of plant essential oils.
Successful infection by Listeria monocytogenes is dependent upon a range of bacterial extracellular proteins including a cytolysin termed listeriolysin O and phosphatidylcholine-specific phospholipase C. Five plant essential oils--bay, clove, cinnamon, nutmeg and thyme--significantly reduced the production of listeriolysin O by L. monocytogenes. The greatest change was observed after culture wi...
متن کاملSubinhibitory concentrations of linezolid reduce Staphylococcus aureus virulence factor expression.
The influence of the antibiotic linezolid on the secretion of exotoxins by Staphylococcus aureus was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis combined with matrix-assisted laser desorption ionization-time of flight mass spectrometry and Western blot analysis. S. aureus suspensions were treated with grading subinhibitory concentrations of linezolid (12.5, 25, 50, and...

15 صفحه اولProduction of listeriolysin by beta-hemolytic strains of Listeria monocytogenes.
Listeriolysin was isolated from target rabbit erythrocyte membranes after lysis of the cells with partially purified toxin derived from a culture supernatant of Listeria ivanovii. The membrane form of the toxin exhibited properties similar to those previously found for streptolysin O. Detergent-solubilized, delipidated listeriolysin was found to comprise a heterogeneous population of partially ...
متن کاملListeriolysin as a virulence factor in Listeria monocytogenes infection of neonatal mice and murine decidual tissue.
Listeriolysin is a 60-kDa protein which allows the growth of Listeria monocytogenes in macrophages and other cells and has been shown to be a virulence factor in Listeria infections of adult mice. However, the neonate and fetoplacental unit are major populations susceptible to listeriosis. Recent data indicate that macrophage and T-cell functions are markedly inhibited in these young mice, and ...
