- ❗ Streptomyces griseolus 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 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 2026-08-13. 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.
