International audience. Strain Marseille-P2341(T), a nonmotile, nonspore-forming, Gram-stain-positive anaerobic coccus, was isolated in the vaginal specimen of a patient with bacterial vaginosis using culturomics. Its growth occurred at temperatures ranging from 25 to 42 degrees C, with pH between 6.5 and 8.5, and at NaCl concentrations lower than 5%. The major fatty acids were C-18:1n9 (27.7%) and C-16:0 (24.4%). Its genome is 1,671,491bp long with 49.48mol% of G+C content. It is composed of 1,501 genes: 1,446 were protein-coding genes and 55 were RNAs. Strain Marseille-P2341(T) shared 97.3% of 16S rRNA gene sequence similarity with Murdochiella asaccharolytica, the phylogenetically closest species. These results enabled the classification of strain Marseille-P2341(T) as a new species of the genus Murdochiella for which we proposed the name Murdochiella vaginalis sp. nov. The type strain is strain Marseille-P2341(T) (=DSM 102237, =CSUR P2341).
