Staph Aureus
Pathogenesis 6ct |
- Enterotoxins: fast acting, heat stable
-TSS toxin-1 -Exfolatins: skin-exfoliating toxin (involved in -scalded skin sun (SSS) -Bulbous Impetigo) -Proiten A binds to Fc of IgG... inhibits Phagocytosis -coagulase -cytolytic toxin (alpha toxin) |
- Enterotoxins: fast acting, heat stable
-TSS toxin-1 -Exfolatins: skin-exfoliating toxin (involved in -scalded skin sun (SSS) -Bulbous Impetigo) -Proiten A binds to Fc of IgG... inhibits Phagocytosis -coagulase (with staph it is localized) (Strep is spread) -cytolytic toxin (alpha toxin) |
|
