Diphyllobothrium nihonkaiense (Yamane et al., 1986) in Switzerland: First molecular evidence and case reports

Abstract: We report the first cases of locally-acquired Diphyllobothrium nihonkaiense (Yamane, Kamo, Bylund and Wikgren, 1986) in Switzerland, confirmed by genetic analysis (18S rRNA, COI and ITS1-5.8S rRNA-ITS2 genes). Diphyllobothriasis in this country is attributed to the tapeworm D. latum (Linnaeus, 1758) but the increasing popularity of raw fish culinary specialities (sushi, carpaccio, tartare) brings out a new diagnostic problem, so that people can get infected by exotic species of tapeworms.
