- 🎓 Name mentioned 17 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 species itself.
- 🧍 The Latin i, when used as a consonant, is often printed as j in earlier dictionaries and classical texts. It is true that this practice has become rare. However, a such change should be applied to many nomenclatural names (examples: Janibacter, Janthinobacterium, …) that is not desirable, because an essential point in nomenclature is the stability of names [Principle 1 of the Bacteriological Code (1990 revision)]. Publication: Gaffiot F. Dictionnaire latin français. Hachette, Paris, 1934.
- 🧍 The spelling of the specific epithet is adjacens in the nomenclatural name Streptococcus adjacens and adiacens in the nomenclatural name Abiotrophia adiacens. Y. Kawamura et al. used adiacens because the IJSB editor recommended to use i instead of j [1]. — Frederiksen W. Personal communication, unspecified date.
