Abstract

Strains of a novel anaerobic, Gram-negative coccus were isolated from the supra-gingival plaque of children. Independent strains from each of six subjects were shown, at a phenotypic level and based on 16S rRNA gene sequencing, to be members of the genus . Analysis revealed that the six strains shared 99.7 % similarity in their 16S rRNA gene sequences and 99.0 % similarity in their gene sequences. The six novel strains formed a distinct group and could be clearly separated from recognized species of the genus of human or animal origin. The novel strains exhibited 98 and 91 % similarity to partial 16S rRNA and gene sequences of ATCC 10790, the most closely related member of the genus. The six novel strains could be differentiated from recognized species of the genus based on partial 16S rRNA and gene sequencing. The six novel strains are thus considered to represent a single novel species of the genus , for which the name sp. nov. is proposed. The type strain is CF100 (=CCUG 54233=DSM 18960).
