Cholera (CALL er uh) is a disease caused by Vibrio cholerae bacteria. Cholera gets into the body through contaminated water or food. Severe diarrhea from cholera can kill a person in just a few hours. The cholera toxin causes intestinal cells to pump out their chloride ions. Soon, there is almost no chloride in the cell, but still a lot of water. Predict what happens next, describe how it happens, and explain the effect it has on the cells.
