[Neutralizing activity of antisera to E. coli enterotoxin and a toxoid type preparation].
Antisera obtained as a result of immunization of rabbits with concentrated E. coli enterotoxin, its active fraction or toxoid, had a pronounced toxin-neutralizing activity. At the same time the cytotoxic activity of antisera to the purified fraction was considerably higher than that of the antisera to the concentrated enterotoxin. Such antisera had also a neutralizing effect on thermolabile enterotoxin. The neutralizing activity of antisera to E. coli enterotoxin was clearly manifested in the paw edema test.
