Toxin absorbed through the intestinal wall of guinea-pigs and toxoided produced an anamnestic response on injection into basically-immune rabbits, but had no effect on fully susceptible rabbits. By dosing sufficient toxin or toxoid per os to basically-immune rabbits anamnestic responses could be produced.Article consists of 3 pages. Contains reference list and 3 tables.en©South Africa.
