Notes:
- Bifidobacterium inopinatum is the correct name 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.

On the basis of HSP60 DNA sequences, Bifidobacterium inopinatum Crociani et al. 1996 and Bifidobacterium denticolens 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.
