Abstract
The antigenic cross-reactivity of staphylococcal enterotoxins types A, B, and C was assessed using anti-A and anti-B antitoxins in the solid-phase radioimmunoassay test. Heterologous reactions were observed. At the 33% inhibition level, B was 18,000 and 5,400 times more effective as an inhibitor in its homologous system than were the heterologous enterotoxins A and C, respectively. Similarly, in the A system, A enterotoxin was 55,000 and 25,000 times more effective than were B and C toxins, respectively, in inhibiting A-anti-A reactions.
