Abstract

SUMMARY: A streptococcus reacting with both group D and group N specific antisera was found to belong to group D; the reaction with the group N serum was shown by reciprocal absorption tests to be due to a common type antigen. Two group D strains were encountered having this antigen; both were identified as The group N strain possessing this same antigen was It proved to have at least one other type antigen, also found in another strain of which was not serologically identical. Two antigenic variants were present in cultures of this organism; one possessed all the type antigens characterizing this strain the other had only one. Attempts to cause further dissociation or reversion were not successful.
