Vagococcus elongatus sp. nov., isolated from a swine-manure storage pit.

A polyphasic taxonomic study was performed on an uncharacterized Gram-positive, catalase-negative, elongated coccus-shaped bacterium isolated from a swine-manure storage pit. The bacterium, designated strain PPC9(T), was facultatively anaerobic and had a DNA G+C content of 44.5 mol%. Comparative 16S rRNA gene sequencing indicated that the bacterium represented a novel subline within the genus Vagococcus, close to but distinct from Vagococcus lutrae. Strain PPC9(T) was readily distinguished from the five recognized species of the genus Vagococcus by using biochemical tests and molecular genetic analysis. Based on phylogenetic and phenotypic evidence strain PPC9(T) is considered to represent a novel species of the genus Vagococcus, for which the name Vagococcus elongatus sp. nov. is proposed. The type strain is PPC9(T) (=CCUG 51432(T)=NRRL B-41357(T)).
