An inter-Group common antigen was detected between Group A type 28 (Small) - and Group F (21/58/O'Mahoney, Colindale) -streptococcal cells by the T-typing agglutination reaction. The characteristics of this antigen coincide with those of the 28R-antigen, which was first detected in the Group A type 28 (Small) cell's by Lancefield in 1943, in the following points : 1) It can beextract ed from the cells with HC1 at pH 2.0 at 100 C in a stable state; 2) It can be kept in a stable state by heating in an alkaline solution at pH 7.8; 3) The antigen on the heat-killed cells was not affected by trypsin digestion at pH 7.8 but was destroyed by pepsin digestion at pH 2.0.
