- 🪓 Organisms assigned to this species have previously been classified as Prevotella intermedia (Holdeman and Moore 1970) Shah and Collins 1990. 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. 🇬🇧
- 🫡 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as 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 not taxonomically suspended any more in favour of Prevotella intermedia (Holdeman and Moore 1970) Shah and Collins 1990. 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. 🇬🇧
