Abstract

Thirteen selected strains of ‘S. milleri’ were compared with the type strains of S. anginosus, S. constellatus and S. intermedius. They contain the same peptidoglycan type (Lys-Ala1-3), their DNA base composition is in the range of 36 to 39 mol% G+C and all strains hydrolyze arginine, salicin and esculin and do not produce acid from mannitol, sorbitol or inulin. DNA-DNA hybridization studies were performed with eight strains of S. milleri and the type strains of S. anginosus, S. constellatus and S. intermedius. Under stringent hybridization conditions S. anginosus and S. constellatus show DNA homology values of less than 50% to each other. S. intermedius is more closely related to S. constellatus than to S. anginosus. Five of the eight strains of ‘S. milleri’ could be allocated to S. constellatus and three to S. anginosus. Unfortunately, all phenotypic markers studied so far do not unequivocally distinguish these two species.
