Factors affecting the regulation of staphylococcal enterotoxin B.
Several factors which regulate the synthesis of enterotoxin B were examined in Staphylococcus aureus S-6 and in its heme-requiring mutant S-6H2. The kinetics of enterotoxin B synthesis during anaerobic growth were identical to those observed under aerobic conditions; extracellular enterotoxin accumulated in the medium during the transition between exponential and stationary phase growth. Strain...
متن کاملNeutralization of Staphylococcal enterotoxin B by aptamer
12 Staphylococcal enterotoxin B (SEB) is a major virulence factor for 13 Staphylococcal toxic shock syndrome (TSS). SEB activates a large subset of the T 14 lymphocytic population, releasing pro-inflammatory cytokines. Blocking 15 SEB-initiated toxicity may be an effective strategy for treating TSS. Using a 16 systematic evolution of ligands by exponential enrichment (SELEX) process, we 17 iden...
متن کاملPurification of Type B Staphylococcal Enterotoxin.
Frea, James I. (University of Wisconsin, Madison), Elizabeth McCoy, and F. M. Strong. Purification of type B staphylococcal enterotoxin. J. Bacteriol. 86:1308-1313. 1963.-A procedure for the production and isolation of type B staphylococcal enterotoxin in yields up to 4 mg per liter of toxic culture is presented. Staphylococcus aureus S6 was grown in shake flask cultures at 37 C for 24 hr in a ...
متن کاملHydrogen ion equilibrai of staphylococcal enterotoxin B.
Potentiometric and spectrophotometric titrations of staphylococcal enterotoxin B have been carried out in 0.16 M KC1 at 25”. Potentiometric titration results indicate that the titration curves are essentially reversible between pH 1.50 and 11.0. All of the ionizable groups in enterotoxin B found from the titration curves are consistent with the amino acid composition which has been reported in ...
متن کاملGenetic Fingerprinting of Staphylococcal Enterotoxin B
Staphylococcal enterotoxin B (SEB), an exotoxin produced by staphylococcal aureus, is commonly associated with food poisoning and capable of triggering flu-like symptoms resembling those of endotoxins – such as lipopolysaccharide (LPS) released from gram-negative bacterial cell walls. By comparing the host response to these distinct toxins on a genetic level, a set of genes can be identified to...
