  • 🎓 Name mentioned 1 time in PubMed until 2024-03-27.
  • 🧍 Illegitimate according to IJSEM 66:4910-4912 (Taxonomic Note by B. Tindall); type (description and illustration by Hoshina [1962]) not the same as of Edwardsiella tarda. Publication: Tindall BJ. On the synonymy of Edwardsiellatarda Ewing and McWhorter 1965 (Approved Lists 1980) and Edwardsiellaanguillimortifera (Hoshina 1962) Sakazaki and Tamura 1975 (Approved Lists 1980), an old problem in need of a solution. Int J Syst Evol Microbiol 2016; 66:4910-4912.
  • 🧍 Consequently, the two names remain homotypic synonyms [3]. Publication: De Vos P, Trüper HG, Tindall BJ.

  • 🧍 Edwardsiella anguillimortifera (Hoshina 1962) Sakazaki and Tamura 1975 (Approved Lists 1980) and Edwardsiella tarda Ewing and McWhorter 1965 (Approved Lists 1980) have the same type strain and Edwardsiella anguillimortifera (Hoshina 1962) Sakazaki and Tamura 1975 (Approved Lists 1980) is the earlier synonym. However, Farmer et al. 1976 [1] have submitted a Request for an Opinion to conserve the specific epithet tarda over the specific epithet anguillimortifera.

  • 🧍 No action was taken on the request, because the request has been withdrawn [2]. Publication: Holt JG. INTERNATIONAL COMMITTEE ON SYSTEMATIC BACTERIOLOGY, JUDICIAL COMMISSION: Minutes of the meeting, 3 September 1978, Munich, West Germany. Int. J. Syst. Bacteriol. 1979; 29:267-269.
