Q

Mechanisms of Bacteria-Induced Injury

A
  1. Bacterial Virulence
    • Depends on ability of bacteria to adhere, invade and delivere toxins
  2. Bacterial Adherence
    • Entry into macrophages directed by receptors that recognize antibodies
    • Entry into epithelial cells- depend on bacteria surface and epithelial cell receptor (integrins)
  3. Bacterial Endotoxin
    • LPS- induces host cytokine release
  4. Bacterial Exotoxins
    • Toxins released that interfere with cellular metabolism and allow bacteria to outgrow competing bacteria
