🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Balutia"; "Blautium"; "Blautra"; "Ktlautia".
💁 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: 21; KCTC: 14; JCM: 14; CGMCC: 12; ATCC: 5; NBRC: 5; CCUG: 4; LMG: 3; CSUR: 3; CIP: 2.
😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 1". — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
🧍 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.Publication:
