Binomial name
Fusobacterium necrophorum

Fusobacterium necrophorum is the causative organism of Lemierre's disease and appears to cause approximately 10% of acute sort throats^[1] and 21% of persistent or recurrent sore throats,^[2][3] (the remainder being Group A streptococci or viruses)

Older text books often state that F. necrophorum is a commensal of the human oropharynx, but this now appears to be untrue, and that when it is present, it is always a pathogen.^[1][2]

F. necrophorum infection usually responds to treatment with penicillin or metronidazole, but penicillin treatment for persistent pharyngitis appears anecdotally to have a higher relapse rate, although the reasons for that are unclear.
