- ❗ Xanthomonas fuscans 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 Xanthomonas.
- 🎓 Name mentioned 26 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 other species in the genus.
