Who discovered Diphyllobothrium Latum?

Diphyllobothrium infection generally occurs in the Northern Hemisphere (Europe, newly independent states of the Former Soviet Union, North America, Asia), but has been reported in Uganda and Chile. Fish infected with Diphyllobothrium larvae may be transported to and consumed in any area of the world.

How is diphyllobothriasis presented?
Diphyllobothriasis is caused by ingestion of raw, undercooked, or unfrozen infected fish and subsequent intestinal infection. The main causative organisms are D latum and D nihonkaiense, but other Diphyllobothrium and similar species have also been reported as infecting agents, albeit much less frequently.
How is diphyllobothriasis treated?
Treatment of diphyllobothriasis is with a single oral dose of praziquantel 5 to 10 mg/kg. Alternatively, a single 2-g dose of niclosamide (unavailable in the US) is given as 4 tablets (500 mg each) that are chewed one at a time and swallowed. For children, the dose is 50 mg/kg (maximum 2 g) once.
