Abstract

Summary: The non-pathogenic beta-haemolytic streptococci from milk, forming Lancefield’s group E, were physiologically defined as and . They were found to fall into four serological types. Fractionation with ethanol showed that both group- and type-specific fractions of these organisms are of polysaccharide nature which probably accounts for the success in using formamide extracts for the type-precipitin reactions. possesses two type antigens, only one of which is also found in .
