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...
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 ...
BACKGROUND Recent literature suggests that Staphylococcal enterotoxin specific IgE may be a risk factor for asthma. OBJECTIVE To investigate the associations between Staphylococcal enterotoxin sensitization and asthma. METHODS A systematic review and meta-analysis was performed for relevant case-control or population-based studies, published in the peer-reviewed journals until February 2013...
The production of staphylococcal enterotoxin A and staphylococcal enterotoxin B was investigated in S. aureus isolates obtained from milk of clinically healthy sheep. In comparison with valid standard (up to 1. 10 CFU. ml), the S. aureus counts were higher in 36 of the total number of 46 positive milk samples (ranging from 1.2. 10 to 8.2. 10 CFU. ml). Six (13.0%) of the 46 isolates were enterot...
Staphylococcal superantigens (SAG) are implicated in the inflammation of atopic dermatitis. As SAG mediated diseases may be modified by specific antibodies, the antibody response to SAG in atopic dermatitis was investigated. Immunoglobulin (Ig) G to staphylococcal enterotoxin A (SEA), staphylococcal enterotoxin B (SEB), and toxic shock syndrome toxin 1 (TSST-1) were measured by sandwich enzyme ...
Bacterial staphylococcal enterotoxin B is involved in several severe disease patterns and it was therefore used as a target for the generation of biologically stable mirror-image oligonucleotide ligands, so called Spiegelmers. The toxin is a 28 kDa protein consisting of 239 amino acids. Since the full-length protein is not accessible to chemical peptide synthesis, a stable domain of 25 amino ac...
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 ...
