title: Fermentative and serological studies on Propionibacterium acnes.
abstract: Seventy-two Propionibacterium acnes strains, among which were five from the American Type Culture Collection, five from the Center for Disease Control, and four of group II of Voss, were thoroughly examined both biochemically and serologically. On the basis of the fermentation of inositol, maltose, mannitol, and sorbitol, eight biotypes were distinguished. By means of tube agglutination tests with the five absorbed antisera, 95, C51, D34, S140, and Beck, 11 serotypes were defined. The biotypes and serotypes showed no striking relationship to each other. Combined biotyping and serotyping is suggested for subdivision of the P. acnes species.
