Abstract

Taxonomic studies were performed on 13 clinical isolates (ten of which were epidemiologically related) that had been previously identified as . Comparative phylogenetic analysis, based on 16S rRNA gene sequences, indicated that the isolates are closely related to with sequence similarity values ranging from 99·5 to 99·8 %. Chemotaxonomic results (fatty acid profiles and menaquinones) supported the inclusion of these isolates in the genus . The DNA G+C content was 74·5 mol%. The results of DNA–DNA reassociation, whole-cell sugars (with galactose as the characteristic whole sugar) and phenotypic properties, including antimicrobial resistance, indicated that these isolates are representatives of a novel species of the genus . The name sp. nov. is proposed for the novel strains, with strain W6122 (=ATCC BAA-886=DSM 16025=CCUG 50705) as the type strain. The definition of this novel species will assist in the understanding of the epidemiology and clinical significance of these micro-organisms.
