• Notes:
  • Erwinia carotovora subsp. betavasculorum is the correct name 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 Erwinia carotovora within a separate genus Erwinia.
  • The full TRBA 466 classification is: risk group = 1, note = "p".
