Phenotypic charcteristics including the abilites two hydrolyze tannin and to decarboxylate gallic acid in 31 strains of S. bovis and 3 strains of S. equinus were compared with their dexoyribonucleic acid (DNA) relatedness. It was found that the strains capable of decarboxylaring gallic acid all belong to a single DNA homology group which does not include either the type strain of S. bovis or the type strain of S. equinus. Thus it was concluded that the gallate degrading strains of S. bovis should be re-assigned to a new species, for which the name Streptococcus gallolyticus sp. nov. is proposed.
