- 🥱 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. This name is not taxonomically suspended any more (but still isn't preferred) in favour of Clostridium perfringens (Veillon and Zuber 1898) Hauduroy et al. 1937 (Approved Lists 1980). Publication: Hauduroy P, Ehringer G, Urbain A, Guillot G, Magrou J. Dictionnaire des bactéries pathogènes. Masson and Co., Paris, 1937. Skerman VBD, McGowan V, Sneath PHA.
