• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Acholeplasma Edward and Freundt 1970 (Approved Lists 1980). Publication: Tully JG, Razin S. Acholeplasma axanthum, sp. n.: a new sterol-nonrequiring member of the Mycoplasmatales. J Bacteriol 1970; 103:751-754.
  • ❗ Haploplasma is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: NCTC: 3; ATCC: 3.
