• Notes:
  • 🚋 The type species of this genus has alternatively been placed in the genus Mycoplasma Nowak 1929 (Approved Lists 1980). Publication: Jordan FTW, Erno H, Cottew GS, Hinz KH, Stipkovits L. Characterization and taxonomic description of five mycoplasma serovars (serotypes) of avian origin and their elevation to species rank and further evaluation of the taxonomic status of Mycoplasma synoviae. Int. J. Syst. Bacteriol. 1982; 32:108-115.
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Malacoplasm".
  • 🎰 The BRCs most frequently used for deposits in this group are: ATCC: 4; DSM: 2; NCTC: 2; CCUG: 1.
  • 🧍 See also Gupta and Oren (2020). The Request by Balish et al. (2019) was denied in Opinion 122 because it was concluded that the Request was based on a misinterpretation of the Code. Publication: Gupta RS, Oren A. Necessity and rationale for the proposed name changes in the classification of Mollicutes species. Reply to: 'Recommended rejection of the names Malacoplasma gen. nov., Mesomycoplasma gen. nov., Metamycoplasma gen. nov., Metamycoplasmataceae fam. nov., Mycoplasmoidaceae fam. nov., Mycoplasmoidales ord. nov., Mycoplasmoides gen. nov., Mycoplasmopsis gen. nov.
