• Notes:
  • ⏰ According to Lai et al. (2010), this species is an earlier heterotypic synonym of Ruegeria pelagia Lee et al. 2007. Publication: Lai Q, Yuan J, Li F, Zheng T, Shao Z. Ruegeria pelagia is a later heterotypic synonym of Ruegeria mobilis. Int J Syst Evol Microbiol 2010; 60:1918-1920. 🇨🇳
  • ❗ Ruegeria mobilis 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 Ruegeria.
  • 😷 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.
