Outline of Final Research Achievements |
During the onset of invasive streptococcal diseases, bacteria systemically disseminate via the bloodstream. The exact mechanism by which pathogenic streptococci evade host immunity and disseminate to the bloodstream remains elusive. In this study, we revealed factors of pathogenic streptococci, including Streptococcus pneumoniae, Streptococcus pyogenes, and oral streptococci, involved in tissue invasion, immune evasion, and bacterial survival in the blood stream.
