Notes:
- Yilmaz et al. (2014) assigned this genus to the order Clostridiales Prévot 1953 (Approved Lists 1980). Publication: Yilmaz P, Parfrey LW, Yarza P, Gerken J, Pruesse E, Quast C, Schweer T, Peplies J, Ludwig W, Glöckner FO. The SILVA and “all-species living tree project (LTP)” taxonomic frameworks. Nucleic Acids Research 2014; 42(D1):D643-D648.
- The type species of this genus has alternatively been placed in the genus Clostridium Prazmowski 1880 (Approved Lists 1980). Publication: Kaneuchi C, Benno Y, Mitsuoka T. Clostridium cocoides, a new species from the feces of mice. International Journal of Systematic Bacteriology 1976; 26:482-486.
- This taxon name is occasionally misprinted in some sources as: "Blautium".
- Taxonomists who have recently focused on this group are the corresponding authors of Shin et al. (2018). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
- The BRCs most frequently used for deposits in this group are: DSM: 19; JCM: 14; KCTC: 9; ATCC: 5; NBRC: 4; CGMCC: 4; CCUG: 4; CIP: 2; NCTC: 1.
- 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. The type strain of Ruminococcus obeum is 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 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.
