    • 🎓 Name mentioned 9999 times (maxed out) in PubMed until 2026-06-11.
    • 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself.
    • ⚠ This name is retained (and recommended for medical use. This will change in the future) instead of Pseudomonas paraeruginosa Rudra et al. 2022.
