Notes:
- ⏰ According to Dellaglio et al. (2006), this species is an earlier heterotypic synonym of Lactobacillus durianis Leisner et al. 2002. Publication: Dellaglio F, Vancanneyt M, Endo A, Vandamme P, Felis GE, Castioni A, Fujimoto J, Watanabe K, Okada S. Lactobacillus durianis Leisner et al. 2002 is a later heterotypic synonym of Lactobacillus vaccinostercus Kozaki and Okada 1983. Int J Syst Evol Microbiol 2006; 56:1721-1724. 🇮🇹
- ❗ Lactobacillus vaccinostercus 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 Lactobacillus.
- ✏ The authority of the taxon name (Kozaki and Okada) deliberately differs from the authors of the publication (Okada et al.).
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — 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.
- 🎓 Name mentioned 8 times in PubMed until 2026-06-11.
- 🙅 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded risk group of other species in the genus.
- 🧍 On the Validation List no. 10, the type strain ATCC 33310 is incorrectly cited as ATCC 3310. Publication: Anonymous. Validation list no. 11. Validation of publication of new names and new combinations previously effectively published outside the IJSB. Int J Syst Bacteriol 1983; 33:672-674.
