Nov. These proposals contravene the Rules of the International Code of Nomenclature of Prokaryotes (ICNP). Neotype strains can only be established following a formal proposal in the International Journal of Systematic and Evolutionary Microbiology in accordance with Rule 18c and Appendix 7 of the ICNP. A proposed neotype becomes an established neotype after 2 years, provided that no objections were submitted to the Judicial Commisson of the International Committee on Systematics of Prokaryotes within the first year following publication of the request. <jats:italic>F. moorei<\/jats:italic> as proposed by Fitzgerald et al. is a later homotypic synonym of <jats:italic>F. prausnitzii<\/jats:italic>. It cannot be a \u2018nom. nov.\u2019 (nomen novum): based on Rule 34a of the ICNP: this term is only used when an author transfers a species to another genus or a subspecies to another species as a new combination, but the original specific epithet cannot be used as \u2018comb. nov.\u2019 (combinatio nova) as a result of homonymy. Moreover, ATCC 27768 and NCIMB 13872 cannot be proposed as the type strain of <jats:italic>F. moorei<\/jats:italic> as these remain permanently associated with the type strain of <jats:italic>F. prausnitzii<\/jats:italic> unless the Judicial Commission of the ICSP will decide otherwise.<\/jats:p>","DOI":"10.1186\/s12864-020-6680-3","type":"journal-article","created":{"date-parts":[[2020,4,30]],"date-time":"2020-04-30T12:02:45Z","timestamp":1588248165000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["On neotypes and nomina nova: commentary on \u201cComparative analysis of Faecalibacterium prausnitzii genomes shows a high level of genome plasticity and warrants separation into new species-level taxa\u201d, by C.B.
