The relationship of type specific M antigen content, streptolysin O titer, serological M type and proteinase production among 173 strains of group A streptococci isolated from scarlet fever patients were studied. As a medium, Todd-Hewitt broth (Difco) was used for culture. The results obtained were as follows: 1) Out of 173 strains, 92 strains (53.2%) were enzyme negative or trace of enzyme production. 2) In accordance with increasing of enzyme activity, the M antigen content and streptolysin O titer were decreased. Average streptolysin O titer of enzyme-negative strains was 111.5 HD50/ml. 3) As compare with other serotypes, many strains of type 12 produced the enzyme in various extent. Out of 105 strains of type 12, 66 strains (62.9%) were enzyme-positive.
