{{DISPLAYTITLE:''Fusobacterium necrophorum''}}

== Background ==

* [[Cellular respiration::anaerobic|Anaerobic]] [[Stain::Gram-negative]] or [[Stain::Gram-variable]] [[Shape::bacillus]] within the genus [[Genus::Fusobacterium]]
* Previously known as ''Bacillus necrophorus''

== Clinical Manifestations ==

* Odontogenic infections
* Causative organism of [[Lemierre syndrome]]
* Can spread hematogenously to bone and joint, muscles and soft tissue, liver, spleen, and endocarditis
* Can cause peritonsillar abscess, deep neck space infections, and mediastinitis
* Has been implicated in venous sinus thrombophlebitis, [[meningitis]], and [[brain abscess]] (the latter more often in polymicrobial infection and more commonly involves [[Fusobacterium nucleatum]])

== Management ==

* First-line options include [[piperacillin-tazobactam]], carbapenems, and [[metronidazole]]

== Further Reading ==

* Human Infection with ''Fusobacterium necrophorum'' (Necrobacillosis) with a Focus on Lemierre Syndrome. ''Clin Microbiol Rev''. 2007;20(4):622-659. doi [https://doi.org/10.1128/CMR.00011-07 10.1128/CMR.00011-07]
