General description

Staphylococcal enterotoxin A belongs to the family of staphylococcal exotoxins. It is secreted by Staphylococcus aureus, a Gram-positive bacteria.[1]

Application

Staphylococcal enterotoxin A from Staphylococcal aureus was injected peritoneally in mice to induce sepsis.10
Staphylococcal enterotoxin A from Staphylococcus aureus has been used as an external standard in for the verification of TRANSIA assay kit, RIDASCREEN assay kit and Vidas Set 2 method.[2] For in vitro toxin stimulation of mouse splenocytes.[3]

Biochem/physiol Actions

Staphylococcal enterotoxin A from Staphylococcus aureus is leading agent that causes of food poisoning. A concentration of as little as 0.5 mg/ml is sufficient to result in nausea, vomiting, diarrhea and cramps.8 It stimulates the cell proliferation of peripheral lymphocytes, induces the production of interferons and is important for gut immunity against S. aureus infections.9 It acts as a super antigen for T-lymphocytes.
