The results of DNA-DNA hybridizations and rRNA gene restriction patterns confirmed this finding. The DNA homology data suggested that the two genomic groups represent two subspecies, L. ivanovii subsp. ivanovii and L. ivanovii subsp. londoniensis subsp. nov. The two subspecies can be distinguished biochemically on the basis of the ability to ferment ribose and N-acetyl-β-d-mannosamine. The type strain of L. ivanovii subsp. londoniensis is strain CLIP 12229 (=CIP 103466)., language=, type=
