Clostridium nitritogenes is a species of obligately anaerobic, Gram-positive bacterium in the genus Clostridium. It was originally described as Eubacterium nitritogenes by Prévot in 1940 and was later reclassified as Clostridium nitritogenes in 2018 based on 16S rRNA gene sequence similarity and phenotypic characteristics consistent with the emended definition of the genus Clostridium.
Clostridium nitritogenes was formerly placed within the genus Eubacterium as Eubacterium nitritogenes. Based on 16S rRNA gene sequence analysis showing only 82–85% similarity to the type species of Eubacterium (Eubacterium limosum), and over 98% similarity with Clostridium cluster I species, it was reassigned to the genus Clostridium as a new combination (comb. nov.) by Bernard et al. in 2018.[1]
Morphology and physiology
Cells of C. nitritogenes are straight rods, 0.8–1.6 μm wide and 1.6–16.0 μm long, occurring singly or in short chains and occasionally forming palisades.
Ecology and isolation
The bacterium has been isolated from both soil and human infections, though it is not commonly encountered in routine clinical diagnostics.[1]
