creates a range of exotoxins, which cause gas gangrene as being the devitalised tissue spot expands. Virulence depends upon the exotoxins developed. Alpha toxin, a lecithinase that causes local tissue breakdown, with platelet aggregation, thrombosis and lowered perfusion, extends the region of devitalised tissue. When absorbed systemically, alpha toxin results in haemolysis, cardiac suppression and subsequent harmful shock. Theta toxin (perfringolysin O) also attacks vascular tissues and displays leucocidal activity and so will cause a dysregulated cytokine mediated host response manifesting as poisonous shock.
