Three novel micro-organisms, designated strains OMB115, OMB118 and OMB120, were isolated from dental plaque from golden hamsters fed with a high-carbohydrate diet. The three strains were Gram-positive, facultatively anaerobic rods that lacked catalase activity. Analysis of their partial 16S rRNA gene sequences indicated that these isolates belonged to the genus . They grew under aerobic conditions and each had a DNA G+C content of 53 mol%. On the basis of phylogenetic analyses involving phenotypic characterization and partial 16S rRNA gene sequencing, strain OMB115 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is OMB115 (=JCM 13495 =DSM 17777).
