Notes:
- 😩 Deposits incorrectly indicated in some sources as representing the type strain of this taxon: ATCC 19525; NBRC 14846; NCTC 10146.
- 😷 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. — 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 109 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 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. Sequencing orphan species initiative (SOS): Filling the gaps in the 16S rRNA gene sequence database for all species with validly published names. Syst Appl Microbiol 2013; 36:69-73. 🇩🇪
- 🧍 For the transfer of Haemobartonella canis (ex Kikuth 1928) Kreier and Ristic 1984 to the genus Mycoplasma Nowak 1929 (Approved Lists 1980) it is necessary to substitute a new specific epithet to produce Mycoplasma haemocanis because there is an earlier homonym, Mycoplasma canis Edward 1955 (Approved Lists 1980) [Rules 34a and 41a]. — Mycoplasma haemocanis (Kreier and Ristic 1984) Messick et al. 2002 is a nomen novum, not a combinatio nova as cited in the paper by Messick et al. 2002. — The Latin noun canis -is is in the masculine gender not in the feminine gender as cited in the paper by Messick et al. 2002. Publication: Kreier JP, Ristic M. Anaplasmosis. XII. The growth and survival in deer and sheep of the parasites present in the blood of calves infected with the Oregon strain of Anaplasma marginale.
