Explain how Vibrio cholerae causes cholera without apparent damage to the intestinal epithelium.
a.
This microbe attaches to the surface of intestinal epithelial cells, producing an endotoxin that causes the epithelium to secrete potassium ions. This induces small amounts of water to follow by osmosis, resulting in the watery rice-stool characteristic of the illness.
b.
This microbe causes destruction of the cellular structures underneath the intestinal epithelium—this is what induces the watery rice-stool characteristic of the illness. This leaves the overlying intestinal epithelium intact.
c.
This microbe directly invades the intestinal epithelial cells, but does not kill them. Instead, while multiplying inside them, it causes them to secrete large amounts of chloride ions. This induces water to follow by osmosis, resulting in the watery rice-stool characteristic of the illness.
d.
This microbe attaches to the surface of intestinal epithelial cells, producing an exotoxin…
