- 😷 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 Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 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 18 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 Yarza et al. (2013), an "un-sequenced orphan species where descriptions, illustrations or dead preserved material serve as the type.". Publication: Yarza P, Sproer C, Swiderski J, Mrotzek N, Spring S, Tindall BJ, Gronow S, Pukall R, Klenk HP, Lang E, et al.

- 🧍 Mycoplasma haemomuris Neimark et al. 2002 is illegitimate because it is a homotypic synonym of the type species of Haemobartonella but Haemobartonella has priority over Mycoplasma. The name is a revision of the former classification as "Candidatus Mycoplasma haemomuris" and may not even be validly published. Publication: Neimark H, Johansson KE, Rikihisa Y, Tully JG. Proposal to transfer some members of the genera Haemobartonella and Eperythrozoon to the genus Mycoplasma with descriptions of 'Candidatus Mycoplasma haemofelis', 'Candidatus Mycoplasma haemomuris', 'Candidatus Mycoplasma haemosuis' and 'Candidatus Mycoplasma wenyonii'. Int J Syst Evol Microbiol 2001; 51:891-899. 🇺🇸
- 🧍 In 2001, Neimark et al. proposed the transfer of Haemobartonella muris to the genus Mycoplasma with the Candidatus status: "Candidatus Mycoplasma haemomuris" Neimark et al. 2001. The Candidatus designation is for new, incompletely described taxa, in order to give them a provisional status; changing validly published names to Candidatus would lose their standing in nomenclature. So, Neimark et al. revise "Candidatus Mycoplasma haemomuris" to Mycoplasma haemomuris nom. nov. — For the transfer of Haemobartonella muris (Mayer 1921) Tyzzer and Weinman 1939 (Approved Lists 1980) to the genus Mycoplasma Nowak 1929 (Approved Lists 1980) it is necessary to substitute a new specific epithet to produce Mycoplasma haemomuris because the name Mycoplasma muris McGarrity et al. 1983 already existed [Rules 34a and 41a].
