| Outline of Final Research Achievements |
In this study, we examined whether the culture condition of either aerobic or anaerobic might be influential to the virulence of Streptococcus pneumoniae, which is a facultative anaerobic bacterium. We here demonstrate that the virulence of S. pneumoniae is highly enhanced in vivo when pre-cultured under anaerobic condition compared with aerobic condition. This is the first report, which validated the difference of pathogenicity between aerobic and anaerobic condition. We consider that the results of our study is important for investigating the pathogenesis of facultative bacterium.
