Staphylococcus aureus produces several different types of enterotoxins (SE's). The SE's are short, soluble proteins that are highly stable and resistant to most proteolytic enzymes. They belong to a family of pyrogenic toxins and as such cause an increase in body temperature, immunosuppression and non-specific T-cell proliferation. These activities are referred to as superantigen activity and results from the interaction of SE's with T-cell antigen receptors and the major histocompatibility complex (MHC) on antigen presenting cells. In addition to their superantigen activity, SE's are also emetics (they cause vomiting). The SE's are important in food poisoning. Enterotoxin I is implicated in scarlet fever, toxic shock and bovine mastitis.
