Résumé : The International Committee on Systematics of Prokaryotes (ICSP) oversees the nomenclature of prokaryotes, naming rules and issues Judicial Commission Opinions concerning taxonomy, Bacteriological Code revisions, etc. Mycoplasmology is represented by a subcommittee of experts on behalf of the International Organization for Mycoplasmology (IOM). Taxonomy of Mollicutes standards (Brown et al., 2007) include deposition: (i) type strains into two culture collections; (ii) 16S rRNA gene sequences with phylogenetic analysis; (iii) demonstration type strains differ from known valid species; (iv) assignment to an order, family and genus in the class. (v) description of novel Mollicutes species should also follow the proposed minimal standards for the use of genome data for the taxonomy of prokaryotes in which genome sequence (complete or draft) the proposed type strain is required (this is not required for `Candidatus` assignment) (Chun et al., 2018). Antiserum is no longer required (Firrao and Brown 2012). Submission of Mollicutes to culture collections is imperative to assist the community longer term by accessing strains, retaining them for future work and is required when describing a new species. In 2021 the ICSP reviewed international culture collections accepting depositions of Mollicutes. The following collections indicated they accept strains (*with no charge for deposition, shipping fees apply): USA: ATCC* France: CIP* Germany: DSMZ* Japan: NBRC UK: NCTC* Taiwan: BCRC (case by case review) Taxonomic naming of new species: Recent publications suggest renaming of species to unusual/unconventional names (Gupta and Oren, 2020). The ICSP Mollicutes Subcommittee is committed to retaining nomenclature aligned to the agreed code and existing scientific/clinical practice, retaining standards for authors naming Mollicutes. Balish et al., 2020 recommended rejection of published names within the class Mollicutes. When considering naming new species, we recommend contacting the committee for advice prior to publication, engage with the Mollicute community prior to publication of controversial changes, especially impacting pathogenic relevant bacteria.
