Notes:
- ⏲ According to Kämpfer et al. (2018), this species is a later heterotypic synonym of Streptomyces canus Heinemann et al. 1953 (Approved Lists 1980). Publication: Kampfer P, Ruckert C, Blom J, Goesmann A, Wink J, Kalinowski J, Glaeser SP. Streptomyces ciscaucasicus Sveshnikova et al. 1983 is a later subjective synonym of Streptomyces canus Heinemann et al. 1953. Int J Syst Evol Microbiol 2018; 68:42-46. 🇩🇪
- 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. Notification list. Notification that new names and new combinations have appeared in volume 68, part 1 of the IJSEM. Int J Syst Evol Microbiol 2018; 68:979-981.
- ❗ Streptomyces ciscaucasicus 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 Streptomyces.
- 🧬 The phylogenomic assignment score of this taxon is 0.00205 (N = 4).
- ✏ The authority of the taxon name (Sveshnikova) deliberately differs from the authors of the publication (Gauze et al.).
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1. — 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 5 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 genus.
