Notes:
- ❗ Bifidobacterium denticolens 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 Bifidobacterium.
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 2, note = "PIIC". — The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 1, note = "+". — 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 4 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 risk group 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. 🇬🇧
- 🧍 On the basis of HSP60 DNA sequences, Bifidobacterium denticolens Crociani et al. 1996 and Bifidobacterium inopinatum Crociani et al. 1996 are quite distant from other Bifidobacterium species. This result is in accordance with that of 16S rRNA sequence homology analysis, and led to the view that these two organisms should be removed from the genus Bifidobacterium Orla-Jensen 1924 (Approved Lists 1980) and proposed as new genera in the family Bifidobacteriaceae Stackebrandt et al. 1997.
