Epidemic secretory diarrheal disease caused by Vibrio cholerae, which releases a toxin that stimulates adenylate cyclase. Usually a disease of poverty but well described in returning travelers.
Classically, patients present passing large quantities (liters) of rice-water stools.
Basic laboratory tests are nonspecific. Culture of the organism is definitive, and rapid dipstick tests are available.
Most patients will recover if the effects of the ensuing profound volume depletion are combated by oral and/or intravenous rehydration.
Antibiotics shorten duration and severity of disease, but rising rates of bacterial resistance are becoming problematic.
A secretory diarrheal illness caused by the gram-negative bacterium Vibrio cholerae. Secretion of the cholera enterotoxin leads to continued activity of adenylate cyclase in intestinal epithelial cells and secretion of water and accompanying salts into the gut lumen.
