Another Serologic Type of Streptococcic Bacteriophage

Abstract
Two races of streptococcus bacteriophage, serologically alike and distinct from the 4 previously known serologic types of streptococcus phage A, B, C and D, were recovered from sewage. The new type is designated E. Among 295 strains of streptococci tested, only 1 was found to be highly sensitive to the new race of phage. This strain, No. 985 of Griffith''s type 17, is serologically distinct from 163 strains of streptococcus which were tested for agglutinability in antiserum 985.
