Notes:
- ❗ Bacteroides gingivalis 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.

- 🪓 Organisms assigned to this species have previously been classified as Bacteroides asaccharolyticus (Holdeman and Moore 1970) Finegold and Barnes 1977 (Approved Lists 1980). Publication: Finegold SM, Barnes EM. Proposal that the saccharolytic and asaccharolytic strains at present classified in the species as Bacteroides melaninogenicus and Bacteroides asaccharolyticus. International Journal of Systematic Bacteriology 1977; 27:388-391. Skerman VBD, McGowan V, Sneath PHA. Approved lists of bacterial names. Int J Syst Bacteriol 1980; 30:225-420.
- 🙅 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.
