Production of Antiserum for Staphylococcal Enterotoxin

Staphylococcal Growth and Enterotoxin Production in Meat.

Preliminary attempts were made to explain the association of staphylococcal food poisoning with cooked rather than uncooked meats. The abilities of various meats to support the growth of an enterotoxigenic staphylococcus, and the production of enterotoxin A, were determined. The production of enterotoxin was detected by means of serological procedures. Little or no growth was obtained when the ...

Production of staphylococcal enterotoxin A on cellophage-over-agar.

Up to approximately 50 mug of staphylococcal enterotoxin A per plate was produced by cellophane-over-agar cultures. Enterotoxin was determined by a latex agglutination technique.

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...

Murine monoclonal antibodies against staphylococcal enterotoxin B: production and characterization.

A group of 14 monoclonal antibodies (mAbs) to staphylococcal enterotoxin B (SEB) were obtained by fusion of Sp2/O myeloma cells with spleen cells from female BALB/c mice immunized with commercial SEB. The antibodies belonged to IgG1 and IgG2b subclasses. We evaluated the anti-SEB titres, competition assays and sensitivity of detection by indirect ELISA. Reactivity and cross-reactivity were also...
