Notes:
- ⏲ According to Wang et al. (2005), this species is a later heterotypic synonym of Clostridium sardiniense corrig. Prévot 1938 (Approved Lists 1980). Publication: Wang X, Maegawa T, Karasawa T, Ozaki E, Nakamura S. Clostridium sardiniense Prevot 1938 and Clostridium absonum Nakamura et al. 1973 are heterotypic synonyms: evidence from phylogenetic analyses of phospholipase C and 16S rRNA sequences, and DNA relatedness. Int J Syst Evol Microbiol 2005; 55:1193-1197. 🇯🇵

- ❗ Clostridium absonum 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 Clostridium.

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 = 2. — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 2. — 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 28 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 the species itself.
