- 😩 Deposit incorrectly indicated in some sources as representing the type strain of this taxon: DSM 41461.
- ❗ Streptomyces sporoclivatus 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 authority of the taxon name (Preobrazhenskaya) 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 2025-06-04.
- 🙅 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.
