Abstract
Staphylococcal enterotoxins C1 and C2 elicit the production of antibodies in rabbits that give precipitin reactions with both toxins and gel diffusion plates. These enterotoxins also elicit the production of antibodies that are specific for each of the enterotoxins. Enterotoxin B elicits the production of antibodies in some rabbits that react with enterotoxins B, C1, and C2 in gel diffusion plates and in radioimmunoassay. Antibodies specific for enterotoxin B are produced also. Enterotoxin C1 elicits the production of antibodies that cross-react weakly with enterotoxin B, indicating that the antigenic sites involved in the cross-reactions are not identical in the two toxins. The antibodies have been isolated by affinity chromatography.
