• Synonyms:

  • Name	Kind
    Aeromonas enteropelogenes Schubert et al. 1991	heterotypic synonym, validly published under the ICNP

• Notes:
  • ⏲ According to Collins et al. (1993), this species is a later heterotypic synonym of Aeromonas enteropelogenes Schubert et al. 1991. Publication: Collins MD, Martinez-Murcia AJ, Cai J. Aeromonas enteropelogenes and Aeromonas ichthiosmia are identical to Aeromonas trota and Aeromonas veronii, respectively, as revealed by small-subunit rRNA sequence analysis. Int J Syst Bacteriol 1993; 43:855-856.
  • ❗ Aeromonas trota is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Aeromonas.

  • 🎓 Name mentioned 26 times in PubMed until 2024-03-27.
  • 🙅 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself.
  • 🧍 The erroneously 'corrected' name "tructi" (IJSB 47:908) has been reinstalled: IJSB 48:615. Publication: Trüper HG, De' Clari L. Taxonomic note: erratum and correction of further specific epithets formed as substantives (nouns) "in apposition". Int. J. Syst. Bacteriol. 1998; 48:615.
  • 🧍 In the reference citation of Aeromonas trota Carnahan et al. 1992 (see: Validation List no. 40), the author's name Chakraborty is erroneously cited as Chakrabarty (sic). Publication: Euzeby JP, Kudo T. Corrigenda to the validation lists. Int J Syst Evol Microbiol 2001; 51:1933-1938.
  • 🧍 On the basis of 16S rRNA gene sequence analysis Aeromonas trota Carnahan et al. 1992 was found identical to Aeromonas enteropelogenes Schubert et al. 1991 [1]. Publication: Huys G, Denys R, Swings J. DNA-DNA reassociation and phenotypic data indicate synonymy between Aeromonas enteropelogenes Schubert et al. 1990 and Aeromonas trota Carnahan et al. 1991. Int J Syst Evol Microbiol 2002; 52:1969-1972.
  • 🧍 The original spelling of the specific epithet has been corrected by Trüper and De' Clari 1997 to tructi (L. n. tructus i, trout) [1]. However, in the paper by Carnahan et al., the species name is derived both from the Greek adjective "trotos", meaning "vulnerable" and the modern Latin feminine adjective "trota" meaning "vulnerable". The name Aeromonas trota is therefore fully correct [2]. Publication: Trüper HG, De' Clari L. Taxonomic note: Necessary correction of specific epithets formed as substantives (nouns) "in apposition". Int. J. Syst. Bacteriol. 1997; 47:908-909.
