Corynebacterium group D2 ("Corynebacterium urealyticum") constitutes a new genomic species.

ABSTRACT

Twenty-one Corynebacterium group D2 ("C. urealyticum") strains were found to constitute a tight DNA hybridization group distinct from named Corynebacterium species. The strains of Corynebacterium group D2 had cell wall component type IV, short chain mycolic acids and G+C content of DNA of 65-66 mol %. Corynebacterium group D2 constitutes a genomic species which can be identified by phenotypic tests.
