Abstract
Rabbits were immunized with 4 strains of Clostridium thiaminolyticum. The examined Bacillus, vegetative form, is not sporelized. With these immune sera of animals the agglutination and precipitation were undertaken against Cl.thiaminolyticum, Bacillus aneurinolyticus, Bacillus thiaminolyticus and Clostridium histoliticum H-22. Spontaneous agglutination was removed by a new method. As the results of these examinations, it was evidenced that immune serum has the specific agglutinin of its own, shows ×10240〜×1280 agglutinin titer with the own agglutinogen, but does not react with other strains. Precipitation shows principally the same results as the agglutination. The precipitation and agglutination of the immune sera against Clostridium histoliticum H-22,B.aneurinolyticus and B.thiaminolyticus proved negative.
