Transfer of Erwinia ananas (synonym, Erwinia uredovora) and Erwinia stewartii to the genus Pantoea emend. as Pantoea ananas (Serrano 1928) comb. nov. and Pantoea stewartii (Smith 1898) comb. nov., respectively, and description of Pantoea stewartii subsp. indologenes subsp. nov.

  • ❗ Erwinia ananatis 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 Erwinia.
  • 😷 The risk group for Belgium has been imported on 2024-02-01. The full classification is: risk group = 1, note = "plant pathogen - biological class of risk plant: 2". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1, note = "PP". — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
  • 🎓 Name mentioned 1 time in PubMed until 2025-06-04.
  • 🙅 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 pathogenicity of the species itself.
  • 🧍 Plant pathogenic according to Bull et al. (2007). Publication: Bull CT, De Boer SH, Denny TP, Firrao G, Fischer Le Saux M, Saddler GS, Scortichini M, Stead DE, Takikawa Y. Comprehensive list of names of plant pathogenic bacteria, 1980-2007. Journal of Plant Pathology 2010; 92:551-592.
  • 🧍 In Kilian's opinion [1] the change of the well-established name Erwinia ananas may be a source of confusion. So, with reference to the first Principle of the Bacteriological Code (1990 Revision), Kilian requested that the original name Erwinia ananas be conserved [2]. The Judicial Commission denied this request, and no Opinion will be issued upon this request [3]. Publication: Kilian M. Necessary changes of bacterial names? ASM News 1998; 64:670.
  • 🧍 The original spelling of the specific epithet, ananas (sic), has been corrected by Trüper and De' Clari 1997. Publication: Trüper HG, De' Clari L.
