Ruminococcus obeum Moore et al. 1976, species.
Type strain: (see also StrainInfo.net) ATCC 29174= DSM 25238.
Sequence accession no. (16S rRNA gene) for the type strain: X85101.
Etymology: Gr. n. obeum, egg.
Approved Lists reference: SKERMAN (V.B.D.), McGOWAN (V.) and SNEATH (P.H.A.) (editors): Approved Lists of Bacterial Names. Int. J. Syst. Bacteriol., 1980, 30, 225-420 (Approved Lists of Bacterial Names in IJSEM Online - Approved Lists of Bacterial Names Amended edition).

International Journal of Systematic Bacteriology, 1976, 26, 238-252.

Note: Ruminococcus obeum Moore et al. 1976 (Approved Lists 1980) is clearly a member of the genus ¤ Blautia, as currently defined. The rules of the Bacteriological Code require that the type strains of all new species and subspecies (including new combinations) be deposited in two different collections in two different countries.
In 2008, the type strain of Ruminococcus obeum was only deposited in the ATCC and a second independent deposit, as required by the Code, has not been possible. Consequently, the transfer of this species to the genus ¤ Blautia cannot be made by Liu et al. 2008, because the resulting species name would not conform to the Rules of the Code governing the valid publication of species names and deposit of type material (Rules 27 and 30) and consequently would not be considered to be validly published.
