Abstract:
Two Gram-stain-negative cocci anaerobes were isolated from pig faeces and designated as strains YH-vei2232T and YH-vei2233. Phylogenetic analysis using 16S rRNA gene sequences revealed that the isolates were most closely related to Veillonella rogosae KCTC 5967T, with 97.0% similarity. Analysis of housekeeping gene sequences (rpoB) revealed the strain formed a sub-cluster within the genus Veillonella. The average nucleotide identities between the two isolates and the most closely related strains within genus Veillonella were <75.0%. The major fatty acids were Summed Feature 8 and C16 : 1 ω9c. The cell wall peptidoglycan contained meso-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-vei2232T (=KCTC 25748T=NBRC 116427T) and YH-vei2233 (=KCTC 25749=NBRC 116428) suggest that they represent a novel species of the genus Veillonella, for which the name Veillonella absiana sp. nov. is proposed.
