Abstract:
:Virulence of many bacterial pathogens is based, at least in part, on the action of phospholipases. The consequences may be immediate and direct, as in the action of Clostridium perfringens alpha toxin on red cells or platelets, or subtle, as with phosphatidylinositol-specific phospholipases of Listeria monocytogenes and other bacteria.
