| Research Abstract |
Chile is a country where produces farmed salmon/trout and Japan is one of countries where the salmons are consumed. Since it is known that larvae of broad tapeworms are parasitized in the salmon/trout in Chile and the occurrence of diphyllobothriosis caused by the infection of the larvae is concerned. We investigated the prevalence and intensity of the parasites harboring in salmon/trout in two lakes, Llanquihue and Panguipulli, in southern Chile during 2012 to 2014. We collected 631 larvae from salmon/trout and the larvae were reinforced as being Diphyllobothrium latum and D. dendriticum by DNA analysis. Most larvae were detected in the viscera of salmon/trout, but some were found in the edible muscle. Although little information currently exists on the relationship between D. latum and salmon/trout in the northern hemisphere, it is considered likely that salmon/trout play an important role in the transmission of D. latum to humans in South America.
