  • 🎓 Name mentioned 0 times in PubMed until 2026-06-11.
  • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself.
  • 🧍 According to Hill et al. (1984), on the Approved Lists of Bacterial Names, this nomenclatural name is incorrectly cited as Thermoactinomyces vulgaris Tsiklinsky (sic) 1899. However, the issue in which the original publication appeared uses the spelling "Tsiklinsky, P." more frequently than the spelling "Tsilinsky, P.", hence this correction may be unwarranted.
