    Included Quiz Questions

    1. Contain a secretory injection system
    2. Secreted by bacterium
    3. Most have an AB structure
    4. Often bind receptors on human cells
    5. Break up in cell cytoplasm where they mediate cell damage
    1. To inject toxins directly into human cells
    2. To inactivate host cell receptors, allowing toxins to enter the cell directly
