This work was aimed at the study of the frequency of isolation of beta-hemolytic streptococci from the patients suffering from scarlet fever, producing A and B toxins. Toxigenicity of the microbes was studied in the indirect agglutination test. In 68.4 per cent of cases there were isolate streptococci producing toxin A, and in 22.8 per cent--toxin B. The percentage of strongly toxigenic A-strains constituted 28.2, and of B-strains--0.6. The greatest incidence of the A and B toxigenic streptococci was observed during the autumn-winter period. Among the strains of the 4th--"leading" serological type there were the greatest number of the A-toxigenic variants, and among the streptococci belonging to the I serological type--of the B-toxigenic strains.
