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 1 time 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.
- 🧍 The distinct name Lactobacillus mishanensis from the same publication has a similar spelling. Publication: Angell RC, Freund GE, Willett P. Automatic spelling correction using a trigram similarity measure. Information Processing and Management 1983; 19:255-261.
