Staphylococcal Enterotoxin D

Chromatofocusing in the purification of staphylococcal enterotoxin D.

A chromatofocusing procedure for the purification of staphylococcal enterotoxin D was developed. The purification included the removal of the toxic protein from culture supernatant fluids of Staphylococcus aureus 1151m by batch adsorption with CG-50 resin, chromatofocusing on Polybuffer Exchanger 94, and gel permeation chromatography on Sephacryl S-200. The purity of the staphylococcal enteroto...

Staphylococcal enterotoxin microbial superantigens.

Staphylococcal enterotoxins are a family of structurally related proteins that are produced by Staphylococcus aureus. In addition to their role in the pathogenicity of food poisoning, these microbial superantigens have profound effects on the immune system, which makes them useful tools for understanding its mechanism of action. These molecules (24-30 kDa) are highly hydrophilic and exhibit low...

Staphylococcal Enterotoxin H Induces V

The staphylococcal enterotoxin (SE) family

Staphylococcus aureus plays an important role in numerous human cases of food poisoning, soft tissue, and bone infections, as well as potentially lethal toxic shock. This common bacterium synthesizes various virulence factors that include staphylococcal enterotoxins (SEs). These protein toxins bind directly to major histocompatibility complex class II on antigen-presenting cells and specific Vβ...

Outbreak of staphylococcal enterotoxin food poisoning.

Coagulase positive staphylococci are generally difficult to grow in foodstuffs without substantial temperature abuse and foodborne outbreaks are uncommon. The following incident resulted in the first detection of staphylococcal enterotoxin in food in a Queensland outbreak and is the first reported outbreak of staphylococcal foodborne illness in Queensland since 1997 when 42 people in a Bundaber...
