Virulence Factors
Adherence components (attachment) Capsules (evasion) Invasion enzymes (entry into host, colonization) - hyaluronidase: breaks down the polysaccharide that glues the host cells together - collagenase: breaks down collagen network in connective tissues - fibrinolytic enzymes (e.g., streptokinase) that destroys fibrin of blood clots (escape) - coagulase: promotes blood clotting (protection) - various other proteases, nucleases, lipases Toxins - Exotoxins (including enterotoxins) See - Endotoxins
