== Background ==

* [[Cestodes|Cestode]] also known as broad fish tapeworm
* Most common cause of [[diphyllobothriasis]]
* Other species in the family can also infect humans, including [[Dibothiocephalus nihonkaiense]], [[Dibothriocephalus dendriticus]], [[Diphyllobothrium stemmacephalum]], [[Diphyllobothrium balaenopterae]], and [[Adenocephalus pacificus]]

=== Epidemiology ===

* Life cycle starts with eggs that pass from the feces of the definitive hosts (fish-eating mammals and birds) into the water; they hatch into coracidia, which are ingested by intermediate host (crustaceans); coracidia develop into larvae in the crustacean, which is then eated by a second intermediate host (small fish); in the small fish, it develops into plerocercoid larvae; the infested fish is eaten by the definitive host (or a human), where it develops into its cestode form in the small intestine
* Relatively wide distribution, but most common in the circumpolar and arctic regions

== Clinical Manifestations ==

* Infestations may be chronic, up to 25 years
* Mostly asymptomatic
* Can cause [[vitamin B12 deficiency]]
* Occasionally cause GI symptoms
* Occasionally cause cholecystitis or cholangitis due to migration of the proglottids

== Diagnosis ==

* Identification of ova or proglottids in stool
* May be found incidentally during endoscopy

== Management ==

* [[Praziquantel]] 5 to 10 mg/kg p.o. once
* Alternative: [[niclosamide]] 2 g p.o. (chewed or crushed) once
