  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Christensenella Morotomi et al. 2012. Publication: Liu X, Sutter JL, de la Cuesta-Zuluaga J, Waters JL, Youngblut ND, Ley RE. Reclassification of Catabacter hongkongensis as Christensenella hongkongensis comb. nov. based on whole genome analysis. Int J Syst Evol Microbiol 2021; 71:4774.
  • ❗ Catabacter is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: JCM: 1; CCUG: 1; DSM: 1.
  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 2, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 2". — 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.
