• Notes:
  • ❗ Corynebacterium michiganense subsp. sepedonicum is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Corynebacterium michiganense within a separate genus Corynebacterium.
  • 😷 The taxon name shown here has no risk group assigned, but is the homotypic synonym of Corynebacterium sepedonicum (Spieckermann and Kotthoff 1914) Skaptason and Burkholder 1942 (Approved Lists 1980), which has a risk group (Swiss Confederation) above 1. This may require that the name shown here is not treated as the correct name for practical purposes.
  • 😷 The taxon name shown here has no risk group assigned, but is the homotypic synonym of Clavibacter michiganensis subsp. sepedonicus corrig. (Spieckermann and Kotthoff 1914) Davis et al. 1984, which has a risk group (Swiss Confederation) above 1. This may require that the name shown here is not treated as the correct name for practical purposes.
  • 🙅 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 subspecies. The name is on LoRN because of the recorded risk group of the species itself.
