• Notes:
  • 🙋 This subspecies could be automatically created (rule 40d) by the valid publication of Streptomyces cavourensis subsp. washingtonensis Skarbek and Brady 1978 (Approved Lists 1980) but an explicit description was also provided. Publication: Skarbek JD, Brady LR. Streptomyces cavourensis sp. nov. (nom. rev.) and Streptomyces cavourensis subsp. washingtonensis subsp. nov., a chromomycin-producing sub-species. International Journal of Systematic Bacteriology 1978; 28:45-53.
  • ❗ Streptomyces cavourensis subsp. cavourensis is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Streptomyces cavourensis 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 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.
  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this subspecies. The name is on LoRN because of the recorded risk group of the genus.
  • 🧍 If an author accepts that Streptomyces cavourensis subsp. washingtonensis Skarbek and Brady 1978 is a later heterotypic synonym of Streptomyces griseus (Krainsky 1914) Waksman and Henrici 1948 (Approved Lists 1980), then Streptomyces cavourensis subsp. cavourensis Skarbek and Brady 1978 (Approved Lists 1980) should thereafter be designated simply as Streptomyces cavourensis Skarbek and Brady 1978 (Approved Lists 1980).
