[Immunological cross reactions between polysaccharides of Streptococci groups A and L].
Antibodies on sepharose immunosorbents containing A-polysaccharide-sepharose or synthetic beta-N-acetylglucosamine, were isolated from the sera of rabbits immunized with streptococci, group A, by means of affinity chromatography. Antibodies obtained from some sera with both immunosorbents reacted with streptococcus, group A and L polysaccharides. Partial identity of these polysaccharides was revealed by the immunodiffusion test. Absorption of antibodies with polysaccharides, group A and L, showed their different specificities. These antibodies could apparently be directed against the end parts of molecules of streptococcus, group A polysaccharide.
