Notes:
- ❗ Mycoplasma agassizii 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 Mycoplasma.
- 😷 The risk group for Belgium has been imported on 2024-02-05. The full classification is: risk group = 1, note = "animal pathogen - biological class of risk animal: 2". — The risk group for Germany has been imported on 2026-08-13. The full classification is: risk group = 2, note = "t". — 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 64 times in PubMed until 2026-06-11.
- 🙅 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 the species itself.
- 🧍 According to Rules 27(3) and 30, this name is not validly published, because the original publication makes reference to the deposit of the type strain in a single recognized culture collection. However, according to the Judicial Opinion 81, Mycoplasma agassizii Brown et al. 2001 is considered to be validly published, since deposit in a second culture collection in a different country has been documented.
