STUDIES ON THE ANTIGENIC COMPOSITION OF GROUP A HEMOLYTIC STREPTOCOCCI : II. THE OCCURRENCE OF STRAINS IN A GIVEN TYPE CONTAINING M BUT NO T ANTIGEN

1. Group A hemolytic streptococci have been described which do not agglutinate in anti-T serum because they lack T antigen. 2. Other strains occur which contain T antigen yet do not agglutinate in anti-T serum because T agglutination is blocked by the presence of large amounts of M substance in the...

Sumario:1. Group A hemolytic streptococci have been described which do not agglutinate in anti-T serum because they lack T antigen. 2. Other strains occur which contain T antigen yet do not agglutinate in anti-T serum because T agglutination is blocked by the presence of large amounts of M substance in the streptococci. 3. Strains belonging to a number of types have been analyzed to determine their antigenic composition with respect to M and T antigens.
