Fusobacterium is a genus of obligate anaerobic, Gram-negative,[3] non-sporeforming bacteria[4] belonging to Gracilicutes. Individual cells are slender, rod-shaped bacilli with pointed ends.[5][6] Fusobacterium was discovered in 1900 by Courmont and Cade and is common in the flora of humans.[7][8]

Strains of Fusobacterium can cause several human diseases and infections, including periodontal diseases, Lemierre's syndrome,[9] oral, head, and neck infections, as well as colorectal cancer and topical skin ulcers.[10]

It has been tied to HIV infection and suboptimal immune recovery.[11] Detection of Fusobacterium is typically through surgical retrieval of tissue, fecal tests, or blood tests in patients showing symptoms.[3] Early detection is preferred and helps to prevent further disease progression.[7]

Although older sources state that Fusobacterium is part of the normal flora of the human oropharynx, the current consensus is that Fusobacterium should always be treated as a pathogen.[12] There are thirteen described Fusobacterium strains; the predominant one affecting humans is F. nucleatum,[13] followed by F. necrophorum, which also affects animals, mainly cattle.[14]
