  • 😷 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 3 times in PubMed until 2024-03-27.
  • 🧍 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 2022; 168:0.
  • 🧍 The status of the BEI Resources is not obvious. BEI Resources is funded by the NIAID and managed by ATCC. But it does not appear to be an ATCC collection. — 🧍 The valid publication of the name Stomatobaculum longum is questionable for the following reasons. P.S. The author thanks Dr. Tindall (DSMZ) for his helpful informations. 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.
  • 🧍 The type strain, originally designated "Lachnospiraceae bacterium ACC2", is deposited in BEI Resources (Biodefense and Emerging Infections Research Resources Repository) as strain HM-480. According to the catalog of the BEI Resources, this item can be ordered once a year. Orders over this limit will be sent to National Institute of Allergy and Infectious Diseases (NIAID) for approval before shipment. See http://www.beiresources.org/Catalog/. Such a restriction is not in accordance with Rule 30 (4) which states that organisms deposited in such a fashion that access is restricted [...] may not serve as type strains.
