Final answer:
A person with cholera would have watery diarrhea due to the action of the Vibrio cholerae bacterium in the intestines.
Step-by-step explanation:
A person who has cholera (Vibrio cholerae) would be expected to have watery diarrhea. Cholera is an acute intestinal infection caused by ingesting contaminated water or food containing the Vibrio cholerae bacterium. The bacteria produce a toxin that activates a chloride transporter in the intestines, causing water to be pumped out of the epithelial cells into the gut lumen. This leads to profuse watery diarrhea, often referred to as 'rice water stool.'
