Describe endotoxins and exotoxins. What effects do they each have on infected persons? What will be an ideal response?
Concepts to Consider: Endotoxins are toxins that are released from bacteria after they have died or
lysed. These toxins are a component of the bacterial cell wall or the internal environment and cause
systemic symptoms such as fever and edema. Exotoxins are those released into the environment (host)
by living bacteria. They result in a very broad range of toxin-specific symptoms
