ENTEROTOXIN B
Staphylococcal
Enterotoxin B is produced by a bacterium Staphylococcus aureus. It is
a protein toxin that is more stable than botulinal toxins. It is even
resistant to heat.
It directly irritates the mucosa of the gastrointestinal
tract, causing diarrhea, and stimulates the vagal and sympathetic nerves,
causing vomiting. Less than 1mg of Enterotoxin B is enough to incapacitate
an adult.
Fortunately, it
is not lethal. Initial symptoms will show within 30min-7hour of ingesting
contaminated food, sooner if airborne.
The symptoms are increased salivation,
severe nausea, vomiting, abdominal, watery diarrhea, prostration, lowered
blood pressure, and dizziness. The victim will usually recover within
a day and death only occurs due to excessive dehydration.
