Abstract
The staphylococcal enterotoxins (SEs) are a subgroup of related protein exotoxins in the pyrogenic toxin (PT) family produced by Staphylococcus aureus and Streptococcus pyogenes (1). Like other members of the PT family, the SEs are superantigens and elaborate a set of biological activities linked to their ability to stimulate cells of the immune system (2). These activities contribute to their ability to induce toxic shock syndrome, immunosuppression, and probably other diseases (3). However, as is evident from the fact that they are designated as enterotoxins, the SEs are distinguishable from other members of the PT family by their ability to induce gastroenteritis when ingested. Hence, they are the causative agents in staphylococcal food poisoning (SFP), a very common form of food-associated gastroenteritis in the United States and worldwide (4).
