Description of sp. nov., isolated from pig faeces.

Two Gram-stain-negative cocci anaerobes were isolated from pig faeces and designated as strains YH-vei2232 and YH-vei2233. Phylogenetic analysis using 16S rRNA gene sequences revealed that the isolates were most closely related to KCTC 5967, with 97.0% similarity. Analysis of housekeeping gene sequences () revealed the strain formed a sub-cluster within the genus . The average nucleotide identities between the two isolates and the most closely related strains within genus were <75.0%. The major fatty acids were Summed Feature 8 and C c. The cell wall peptidoglycan contained -diaminopimelic acid. The major metabolic end products of isolates were propionic and acetic acids. The genomic DNA G+C contents of both strains were 40.1 mol%. The chemotaxonomic, phenotypic and phylogenetic properties of YH-vei2232 (=KCTC 25748=NBRC 116427) and YH-vei2233 (=KCTC 25749=NBRC 116428) suggest that they represent a novel species of the genus , for which the name sp. nov. is proposed.
