• Notes:
  • ⏲ According to Bhargava et al. (2024), this species is a later heterotypic synonym of Spiroplasma mirum Tully et al. 1982. Publication: Bhargava V, Lahon D, Gupta S, Kaur J, Lata P. Genome-based reclassification of Spiroplasma atrichopogonis Koerber et al. 2005 as a later heterotypic synonym of Spiroplasma mirum Tully et al. 1982. Int J Syst Evol Microbiol 2024; 74:6589.
  • 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Göker M. Notification list. Notification that new names and new combinations have appeared in volume 74, part 11 of the IJSEM. Int J Syst Evol Microbiol 2025; 75:6619.
  • ❗ Spiroplasma atrichopogonis 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 Spiroplasma.
  • 😷 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 3 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 other species in the genus.
