• Notes:
  • 😩 Deposit incorrectly indicated in some sources as representing the type strain of this taxon: B 6.
  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No". — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1. — 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 7 times in PubMed until 2026-06-11.
  • 🙅 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.
  • 🧍 The culture collection accession numbers ATCC 25655, CIP 105976, DSM 5887, IAM 12617, LMG 129, and NBRC 15761 have been provided on request for validation. Publication: Euzeby JP.

  • 🧍 Thalassobius gelatinovorus (Rüger and Höfle 1992) Arahal et al. 2005 appears in the November 2005 issue of the IJSEM. However, this name was not validly published [see Rule 27(3)]. In order to validly publish this new combination, Thalassobius gelatinovorus (Rüger and Höfle 1992) Arahal et al. 2006 was cited on Validation List 107. — In the effective publication, the basonym is erroneously cited as Ruegeria gelatinovorans (Rüger and Höfle 1992) Uchino et al. 1999.
