Notes:
- ❗ Pseudomonas geniculata 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 Pseudomonas.
- 😷 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 Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — The risk group for Germany has been imported on 2026-08-13. 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 41 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 the genus.
- 🧍 According to Ludwig et al. (2021), this "species affiliates away from its type species and may be reclassified as Stenotrophomonas". Publication: Ludwig W, Viver T, Westram R, Francisco Gago J, Bustos-Caparros E, Knittel K, Amann R, Rossello-Mora R. Release LTP_12_2020, featuring a new ARB alignment and improved 16S rRNA tree for prokaryotic type strains. Syst Appl Microbiol 2021; 44:126218. 🇪🇸
- 🧍 According to Anzai et al., Pseudomonas geniculata (Wright 1895) Chester 1901 (Approved Lists 1980) does not belong to the genus Pseudomonas sensu stricto.
