title: First record of human infection with the tapeworm Diphyllobothrium nihonkaiense in North America.
abstract: The tapeworm Diphyllobothrium nihonkaiense (Cestoda: Diphyllobothriidea), originally described from Japan, is reported from a man in North America for the first time. Species identification was based on sequences of ribosomal (partial 18S rRNA) and mitochondrial (partial Cytochrome c Oxidase subunit I) genes of proglottids expelled from a Czech tourist who ate raw Pacific sockeye salmon (Oncorhynchus nerka) from British Columbia, Canada.
