Notes:
- ❗ Eubacterium rectale is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Eubacterium.
- 😷 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". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 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.
- 🎓 Name mentioned 398 times in PubMed until 2026-06-11.
- 🙅 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded pathogenicity of the species itself.
- 🧍 According to Bartlett et al. (2022), this species is an established human pathogen. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology (Reading) 2022; 168:0. 🇬🇧
- 🧍 According to Rule 18c, the proposal of a neotype strain does not require a Request for an Opinion. Publication: Duncan SH, Flint HJ. Proposal of a neotype strain (A1-86) for Eubacterium rectale. Request for an opinion. Int J Syst Evol Microbiol 2008; 58:1735-1736. 🇬🇧
- 🧍 VPI 0989, the type strain in the Approved Lists of Bacterial Names was deposited in ATCC (ATCC 25578) but was lost in both collections. A different isolate, VPI 0990 = ATCC 33656= CIP 105953, from the same fecal sample has been deposited to represent the type strain. Because these isolates came from the same sample, Moore and Holdeman Moore believe that they are the same strain. According to Rule 18c, a neotype strain must be proposed in the IJSB (now IJSEM) and the proposal by Moore and Holdeman Moore is not in accordance with the rules of the ICNP. The neotype strain VPI 0990 = ATCC 33656= CIP 105953 is not an established neotype (see Rule 18c). Publication: Moore WEC, Holdeman Moore LV. Genus Eubacterium Prévot 1938, 294AL.
