Influences of sigmaB and agr on expression of staphylococcal enterotoxin B (seb) in Staphylococcus aureus.

Canadian journal of microbiology - 1 May 2004

Schmidt Katherine A, Donegan Niles P, Kwan William A, Cheung Ambrose

Abstract excerpt

In Staphylococcus aureus, enterotoxin B (SEB) is a superantigen that activates host interleukins and induces adverse responses, ranging from food poisoning to toxic shock. The alternate sigma factor, sigmaB (SigmaB), and agr are two known regulators of S. aureus. Northern blots of strain COL, a sigB-positive strain, showed an inverse correlation between sigmaB expression and seb message. seb expression was also...
