- ❗ Corynebacterium nigricans 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 Corynebacterium.
- 😷 The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 2. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
- 🎓 Name mentioned 2 times in PubMed until 2024-03-27.
- 🙅 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.

🧍 In the article by Shukla et al. 2003, the etymology is provided as follows: "The name Corynebacterium nigricans (ni' gri-kans) is derived from the word "niger" (L. fr. niger, black)" [sic]!

🧍 In the article by Shukla et al. 2003, the strain ATCC 700975 is erroneously cited as ATCC 700795. — 🧍 The paper by Shukla et al. 2003 only cites the strain ATCC 700795 (sic) as type strain. However, certificate for CIP 107346 has been provided on request for validation.
