Using the culturomics method, two strains were isolated, identified and characterized following the taxonogenomics concept. Megasphaera vaginalis sp. nov. strain Marseille-P4512 (= CSURP4512) and Anaerococcus vaginimassiliensis sp. nov. strain Marseille-P4857 (= CSURP4857) were isolated from the vagina of a French woman. The phylogenic tree, phenotypic criteria and genomic analysis described here clearly show that these two bacteria are different from previously known bacterial species with standing in nomenclature and new members of Firmicutes phylum.
