Outline of Final Research Achievements |
Antixoxidative machineries that eliminate reactive oxygen species are of great benefit to bacteria to grow aerobically and to escape from oxygen-dependent bacterial killing by macrophages. Cysteine persulfide and glutathione persulfide are present abundantly in mammalian cells and act as potent antioxidants. Here we investigated the occurrence of persulfide in Gram-negative bacteria. Roles of persulfide species on bacterial resistance against oxidative stress was studied. Cysteine persulfide and glutathione persulfide/trisulfide were detected in all bacteria studied. Treatment of Salmonella Typhimurium with persulfide donors significantly increased intracellular persulfide levels. More importantly, persulfide boosted bacteria became highly resistant against oxidative stress-mediated bacterial killing induced by hydrogen peroxide challenging and by macrophages. These data suggest the importance of reactive persulfides in bacterial resistance against oxidative stress.
