[Physico-chemical properties of microbial antigens and the immuno-allergic tests].
Experiments were conducted on guinea pigs sensitized by the delayed and immediate types of allergy. Different antigens obtained from the strain of Brucella abortus BA-19 were used for sensitization and the resolving action. Comparison of the resolving properties of the corpuscular, soluble (ultrasound treated) antigens and purified protein fractions, polysaccharide and RNA was carried out in the skin reactions of the immediate and delayed type, passive skin anaphylaxis, acute anaphylactic shock, and the Schults-Dale test. Immediate reactions to the purified protein fraction were weaker than those to the whole soluble antigen, by which the animals were sensitized. Polysaccharide and the RNA-fractions proved to be inactive in the allergic reactions.
