Enterotoxins are a type of exotoxin produced by certain bacteria that specifically affect the small intestine. These toxins disrupt normal intestinal function, leading to symptoms such as vomiting and diarrhea. Enterotoxins are often heat-stable, meaning they can survive cooking temperatures, which can contribute to foodborne illnesses. They work by binding to receptors on the intestinal lining, causing a rapid influx of water and electrolytes into the intestinal lumen. This results in the characteristic watery diarrhea seen in food poisoning. Some enterotoxins also stimulate the release of inflammatory mediators. Common bacteria that produce enterotoxins include Staphylococcus aureus, Bacillus cereus, and Vibrio cholerae. Staphylococcus aureus enterotoxins are often associated with improperly stored food, while Vibrio cholerae produces cholera toxin, a potent enterotoxin responsible for the severe dehydration characteristic of cholera. The diagnosis of enterotoxin-mediated illness typically involves identifying the causative bacteria and sometimes detecting the toxin itself. Prevention focuses on proper food handling and hygiene practices to minimize bacterial contamination and toxin formation.
