Together with 31 other incorrectly formed (i.e. as nominative nouns in apposition) specific epithets, the epithet of Streptomyces scabies was corrected to Streptomyces scabiei in Taxonomic Notes published in 1997 and 1998. A subsequent Request for an Opinion, published in 2001, to reinstate the incorrect epithets for ten of these species was denied by the Judicial Commission in 2002. In 2007, a further Request for an Opinion was submitted to the Judicial Commission which proposed the conservation of the incorrect epithet of Streptomyces ‘scabies’ over the corrected one, scabiei. After having stated once that the corrections made to the epithets were performed according to the correct application of the International Code of Nomenclature of Bacteria (now ‘of Prokaryotes’, ICNP), the Judicial Commission would lose authority and credibility if it were to follow a request to abandon even one of the now correct 32 epithets in favour of its incorrectly formed predecessor. Microbiologists who accept changes in names of genera should also accept the correction of grammatical or orthographical changes in specific epithets.
