  • 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Animal classification RG: 1 - Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No - Containment level: Containment Level 1 - Considerations for containment: This biological agent is capable of causing human and/or animal disease, but is unlikely to do so. Although it poses a low risk to the health of individuals or animals, and a low risk to public health or animal populations, this biological agent may cause opportunistic infections and may pose a threat to immunocompromised individuals or animals, or those with predisposing factors. Refer to the Canadian Biosafety Guideline on Containment Level 1: Physical Design and Operational Practices for recommended best practices for basic laboratory design and the safe handling of risk group 1 biological materials.". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 2. — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 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.
  • 🎓 Name mentioned 56 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 the species itself.
  • 🧍 Re-evaluation of the original taxonomy as Pseudomonas oryzihabitans IJSB 47:251. Publication: Anzai Y, Kudo Y, Oyaizu H. The phylogeny of the genera Chryseomonas, Flavimonas, and Pseudomonas supports synonymy of these three genera. Int J Syst Bacteriol 1997; 47:249-251.
  • 🧍 The level of similarity between the 16S rRNA sequence of the strain KS0036 L-1 AJ 2197 IAM 1568 JCM 2952 (the type strain of the species Pseudomonas oryzihabitans Kodama et al. 1985) and the 16S rRNA of the strain DSM 50071 ATCC 10145 [the type strain of the species Pseudomonas aeruginosa (Schroeter 1872) Migula 1900 (Approved Lists 1980)] is 93.9%. This result suggests that Flavimonas Holmes et al. 1987 is a later heterotypic synonym of Pseudomonas Migula 1894 (Approved Lists 1980) and that the name Pseudomonas oryzihabitans should be used for this species.
