Abstract

A polyphasic analysis was undertaken of seven independent isolates of Gram-negative cocci collected from pathological clinical samples from New York, Louisiana, Florida and Illinois and healthy subgingival plaque from a patient in Virginia, USA. The 16S rRNA gene sequence similarity among these isolates was 99.7–100 %, and the closest species with a validly published name was (96.9 % similarity to the type strain). DNA–DNA hybridization confirmed that these isolates are of the same species and are distinct from their nearest phylogenetic neighbour, . Phylogenetic analysis of 16S and 23S rRNA gene sequences indicated that the novel species belongs in the genus . The predominant cellular fatty acids were C, summed feature 3 (Cω7 and/or iso-C 2-OH) and Cω7. The cellular fatty acid profile, together with other phenotypic characters, further supports the inclusion of the novel species in the genus . The name sp. nov. (type strain 6332  = DSM 25276  = LMG 26725) is proposed.
