  • 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Göker M. Notification list. Notification that new names and new combinations have appeared in volume 75, part 5 of the IJSEM. Int J Syst Evol Microbiol 2025; 75:6824.
  • ❗ Labrys portucalensis 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 Labrys.
  • 🧬 The phylogenomic assignment score of this taxon is 0.12875 (N = 3).
  • 😷 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 14 times in PubMed until 2025-06-04.
  • 🧍 The specific epithet portucalensis is a neo-Latin adjective, not a Latin adjective as cited in the paper by Carvalho et al. 2008. Publication: Euzeby JP. List of Bacterial Names with Standing in Nomenclature: a folder available on the Internet. Int J Syst Bacteriol 1997; 47:590-592. 🇫🇷
