  • Notes:
    • ⏲ According to Committee (2025), this species is a later heterotypic synonym of "Bacillus fragilis" Veillon and Zuber 1898. Publication: Committee AH. Mitigating changes in prokaryotic nomenclature: Definitions and Workflow. Zenodo 2025; 2025:15320329.
    • ❗ Bacteroides hominis 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 Bacteroides.
    • 🎓 Name mentioned 2 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 genus. This name is taxonomically suspended (and therefore not recommended for medical use for now) until no later than 2027 in favour of Bacteroides fragilis (Veillon and Zuber 1898) Castellani and Chalmers 1919 (Approved Lists 1980). Publication: Castellani A, Chalmers AJ. Manual of Tropical Medicine, 3rd ed. Williams Wood and Co., New York, 1919. Skerman VBD, McGowan V, Sneath PHA. Approved lists of bacterial names.
