- 🧍 Clostridium putrificum (Trevisan 1889) Reddish and Rettger 1922 (Approved Lists 1980), Clostridium botulinum (van Ermengem 1896) Bergey et al. 1923 (Approved Lists 1980) and Clostridium sporogenes (Metchnikoff 1908) Bergey et al. 1923 (Approved Lists 1980) are genetically related at the species level and Clostridium putrificum has priority. Olsen et al. 1995, propose rejection of the name Clostridium putrificum on the basis of the Rules 23a note 4 and 56a (5) as a nomen periculosum, and conservation of the name Clostridium botulinum (Rule 23a note 4, Rule 56b note 2), and conservation of the name Clostridium sporogenes for the nontoxigenic strains on the basis of the Rules 23a note 4 and 56b note 2.
