Eight representative Clostridium butyricum rods appear in seven groupings: six isolated straight-to-curved singles and one touching pair.
Morphology reconstruction Editorially reviewed

Representative Clostridium butyricum vegetative rod forms, shown as eight bodies in seven single or paired groupings. This reconstruction is non-diagnostic, shows no visible spores, and is not a micrograph.

Key Features#

Butyrate production: Produces butyrate via the acetyl-CoA pathway, making it functionally similar to Faecalibacterium prausnitzii but with the advantage of spore-forming stability (survives gastric transit, shelf-stable).
