Lagierella Massiliensis Gen. Nov., Sp. Nov., Isolated from a Stool Sample

Strain Marseille-P2012(T) was described to represent a new bacterial genus belonging to the phylum Firmicutes using the taxonogenomics concept. It was isolated from stool samples of a healthy 2-year-old Senegalese boy in a study of the human gut microbiota. This strain is a Gram-positive, anaerobic, non-motile and coccus-shaped bacterium. The 16S rRNA gene sequence of strain Marseille-P2012 exhibited 90.5% similarity with Finegoldia magna strain ATCC 29,328, the phylogenetically closest species with standing in nomenclature. The genome of strain Marseille-P2012(T) is 1,832,315 bp-long with 32.46 mol% of G + C content. With regard to its phenotypic, biochemical and genomic characteristics, this bacterium was classified as a new bacterial genus and species, Lagierella massiliensis gen. nov., sp. nov., with strain Marseille-P2012(T) (= CSUR P2012 = DSM100854) as type strain.
