Emetic potentials of newly identified staphylococcal enterotoxin-like toxins.
Staphylococcal enterotoxins (SEs) are a common causative agent of food poisoning. Recently, many new SE-like (SEl) toxins have been reported, although the role of SEls in food poisoning remains unclear. In this study, the emetic potentials of SElK, SElL, SElM, SElN, SElO, SElP, and SElQ were assessed using a monkey-feeding assay. All the SEls that were tested induced emetic reactions in monkeys...

متن کاملStaphylococcal 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...
متن کاملTransport and processing of staphylococcal enterotoxin A.
A larger-molecular-weight precursor of enterotoxin A was found in membranes of Staphylococcus aureus and was shown to be the kinetic precursor to the extracellular form of the toxin. Subcellular fractionation revealed that mature enterotoxin A was transiently associated with the cell wall before being released to the extracellular environment.
متن کاملIdentification and Characterization of a Novel Staphylococcal Emetic Toxin.
Staphylococcal enterotoxins (SEs) produced by Staphylococcus aureus have superantigenic and emetic activities, which cause toxic shock syndrome and staphylococcal food poisoning, respectively. Our previous study demonstrated that the sequence of SET has a low level of similarity to the sequences of other SEs and exhibits atypical bioactivities. Hence, we further explored whether there is an add...
