• Notes:
  • ❗ Clavibacter xyli 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 Clavibacter.
  • 🎓 Name mentioned 19 times 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 risk group of other species in the genus.

  • 🧍 According to Suzuki et al. 1999 [1], the type strain (L1A = NCPPB 3152 = PDDCC 7127 = ATCC 33974 = LMG 7352) of Clavibacter xyli Davis et al. 1984 is no more available from the authors of the species, the NCPPB, the ICMP (= the PDDCC), the ATCC, and the LMG. However, the strain ICMP 7127 seems available from the ICMP [2]. Publication: Suzuki KI, Suzuki M, Sasaki J, Park YH, Komagata KK.
