Exotoxins Notes:

Endotoxins are responsible for many diseases. For example, cholera, a dangerous diarrheal disease, is caused by an exotoxin secreted by the proteobacterium Vibrio cholerae. The exotoxin stimulates intestinal cells to release chloride ions into the gut, and water follows by osmosis. In another example, the potentially fatal disease botulism is caused by botulinum toxin, an exotoxin secreted by the gram positive bacterium Clostridium botulinum.
