- 📧 The e-mail address of the corresponding author given in the effective publication is not functional any more.
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 2, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 2". — The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 1, note = "+". — 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 3 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.
- 🧍 The phylogenetic position of this species was determined in a genome-scale analysis by Nouioui et al. (2018). Publication: Nouioui I, Carro L, Garcia-Lopez M, Meier-Kolthoff JP, Woyke T, Kyrpides NC, Pukall R, Klenk HP, Goodfellow M, Goker M.

- 🧍 The original spelling, Nocardia senatus (sic), has been corrected on validation according to Rule 61. Publication: Euzeby JP. Validation list no. 98. List of new names and new combinations previously effectively, but not validly, published. Int J Syst Evol Microbiol 2004; 54:1005-1006.
- 🧍 The original spelling, Nocardia senatus (sic), has been corrected on validation according to Rule 61. In the effective publication the etymology is as follows: N.L. gen. n. senatus referring to the colony color of ochre-yellow of the Nocardia. However, the genitive noun senatus means of the Senate (the supreme council in Rome). Consequently, with the authors' agreement, the specific epithet has been changed to sienata.
