[Immune response of rats of inbred strains to the polysaccharide of group A streptococci].

Immune response to polysaccharide of group A streptococcus was studied in rats of inbred strains MCY, VAG and August. Pure antibodies to beta-N-acetylglucosamine were isolated; their chromatography (by affinity) was conducted, and the content of the molecules of the IgG and IgM classes was established in each antibody fraction. Interlinear differences were revealed by each of the signs under study, this pointing to the role of genetic factors in the formation of antibodies to polysaccharide of group A streptococcus.
