Diphyllobothrium nihonkaiense Tapeworm Larvae in Salmon from North America
نویسندگان
چکیده
Diphyllobothriosis is reemerging because of global importation and increased popularity of eating raw fish. We detected Diphyllobothrium nihonkaiense plerocercoids in the musculature of wild pink salmon (Oncorhynchus gorbuscha) from Alaska, USA. Therefore, salmon from the American and Asian Pacific coasts and elsewhere pose potential dangers for persons who eat these fish raw.

Diphyllobothriasis nihonkaiense: possibly acquired in Switzerland from imported Pacific salmon.
A 5-year-old Japanese boy passed tapeworm strobila while he was living in Switzerland. During a short visit to Japan, he was successfully treated with a single dose of praziquantel. DNA sequences of ITS1, cox1 and nd3 genes from the tapeworm were compatible with those of Diphyllobothrium nihonkaiense rather than Diphyllobothrium latum, which is prevalent in Europe. The patient consumed imported...

Infection cases of diphyllobothriid tapeworms are not much in the below teen-age group. We report a case of Diphyllobothrium nihonkaiense infection in a 13-year-old boy. He presented with severe fatigue, occasional abdominal pain at night time. He also had several episodes of tapeworm segment discharge in his stools. By his past history, he had frequently eaten raw fish including salmon and tro...

Diphyllobothrium latum and Diphyllobothrium nihonkaiense are morphologically similar to each other, and only genetic method can differentiate clearly between the 2 species. A strobila of diphyllobothriid tapeworm discharged from a 7-year-old boy was analyzed to identify the species by mitochondrial cytochrome c oxidase subunit 1 (cox1) gene sequencing. He and his family (total 4 persons) ate sl...
متن کاملDiphyllobothriasis Associated with Eating Raw Pacific Salmon
The incidence of human infection with the broad tapeworm Diphyllobothrium nihonkaiense has been increasing in urban areas of Japan and in European countries. D. nihonkaiense is morphologically similar to but genetically distinct from D. latum and exploits anadromous wild Pacific salmon as its second intermediate host. Clinical signs in humans include diarrhea and discharge of the strobila, whic...
