Fusobacterium

Abstract Fu.so.bac.te'ri.um. L. n. fusus a spindle; L. neut. n. bacterium a small rod; N.L. neut. n. Fusobacterium a small spindle‐shaped rod. Nonsporeforming rods that are Gram‐stain‐negative and obligately anaerobic . Metabolize peptone or carbohydrates in PY‐glucose to produce butyrate , often with acetate and lower levels of lactate, propionate, succinate, and formate. DNA G + C content ( mol %): 26–34. Type species : Fusobacterium nucleatum Knorr 1922, 17 AL [ Bacillus fusiformis Veillon and Zuber 1898, 540 and other combinations using “ Fusiformis ” except the organism described as Fusobacterium fusiforme by Hoffman in the 7th edition of the Manual ; Group I, Spaulding and Rettger 1937, 535; Group III (and probably Fusobacterium polymorphum ) Baird‐Parker 1960, 458; not Fusobacterium plauti‐vincentii Knorr 1922, 5.]. Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Fusobacterium is: correct name (last update, February 2025) * .
