“…This is also in line with the experience gained with other serological methods; from the beginning of such studies the diversity of the non-hemolytic streptococci has usually been emphasized as compared with the relative homogeneity of the hemolytic types. (Kligler, 1915;Krumwiede and Valentine, 1916;Swift, 1917, 1918;Howell, 1918;Havens, 1919;Dochez, Avery and Lancefield, 1919;Clawson, 1920;Herrold, 1922;Norton, 1923;Crow, 1933. ) For example, Gordon (1922) found that of 131 cultures of Streptococcus pyogenes, 125 were of the same serological type as revealed by agglutination and agglutinin absorption tests; whereas with 16 cultures of Streptococcus salivarius, at least 12 different types were found by the same methods.…”

“…Some authors (6)(7)(8)(9)(10) have studied strains of non-hemolytic streptococci which were heterogeneous with respect to their sources and their cultural characteristics. Moreover, these strains did not appear to fall into any clearly defined immunological groups when studied by agglutination, agglutinin-absorption, or complement-fixation techniques.…”

In the preceding paper (1) evidence was presented to show that various strains of a non-hemolytic streptococcus, designated streptococcus MG, belong to a homogeneous bacteriological group a n d t h a t the properties of this microorganism appear to characterize it as a distinct and hitherto undifferentiated microbial species. Interest in streptococcus MG was aroused because of the frequency with which strains were isolated from patients with primary atypical pneumonia and because of the development of antibodies against this microorganism in the sera of patients convalescent from the disease (2-4). In the present paper the results of studies concerning the immunological characteristics of streptococcus MG will be described in detail.Numerous attempts have been made to classify the large group of non-hemolytic streptococci by means of immunological methods. The term "non-hemolytic" will
