  • 🎓 Name mentioned 88 times 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.
  • 🧍 According to Bartlett et al. (2022), this species is a putative human pathogen. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology (Reading) 2022; 168:0. 🇬🇧
  • 🧍 Francisco Salva Serra commented on the alleged type-strain deposits of E. kobei as follows: "DSM 13645T is the only deposit of the true type strain of E. kobei (listed in LPSN), which means that all other deposits of the type strain listed in LPSN (except for NIH 1485-79) should probably be deactivated and strain DSM 13645 taken in. The LPSN lists KF516242 as 16S rRNA gene sequence of the type strain of E. kobei, which does not match CP017181. [...] Status of the species: according to Brady et al., 2013, it seems that strain DSM 13645 was used in the emended description of the species (Hoffmann et al., 2005).". — Salva Serra F. Personal communication, 2020-04-27.
