Bacteria damage the body with two very different poisons. An exotoxin is a protein a living cell secretes; an endotoxin is part of the gram-negative cell wall, freed only when the cell dies. Pick a toxin, then tap a feature to compare them side by side.

ExO = Excreted prOtein, made by living cells — often preventable with a toxoid vaccine. ENDo = part of the cell wall (LPS), released at the end when the gram-negative cell dies — the classic driver of fever & septic shock.
