Notes:
- ⏰ According to Johnson and Holdeman (1985), this species is an earlier heterotypic synonym of Bacteroides capillus Kornman and Holt 1982. Publication: Johnson JL, Holdeman LV. Bacteroides capillus Kornman and Holt and Bacteroides pentosaceus Shah and Collins, later synonyms of Bacteroides buccae Holdeman et al. Int. J. Syst. Bacteriol. 1985; 35:114. 🇺🇸
- ⏰ According to Shah and Collins (1990), this species is an earlier heterotypic synonym of Bacteroides pentosaceus Shah and Collins 1982. Publication: Shah HN, Collins DM. Prevotella, a new genus to include Bacteroides melaninogenicus and related species formerly classified in the genus Bacteroides. Int J Syst Bacteriol 1990; 40:205-208. 🇬🇧
- ❗ Bacteroides buccae 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.
