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. S. subacidus possesses two type antigens, only one of which is also found in S. infrequens., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-14-2-268
