尽管鲸类绦虫DiPhylloboys umstemmacephalum同时出现在冷水和暖水中，但人类感染和最终宿主发生仅限于日本及其附近的温带地区。我们最近从日本北部北海道附近意外捕获的一只港口江豚的排泄物中获得了这种鞭毛虫的排泄物。对28S rDNA和cox1基因的遗传分析证实，该尾虫为WASD。球茎草属。我们的发现创造了D的最北记录。在西太平洋发现了茎头虫，这表明日本北部人类感染这种寄生虫的风险值得进一步关注。
Even though the cetacean tapewormDiphyllobothriumstemmacephalumoccurs in both cold and warm waters, human infections and final host occurrences have been confined to temperate areas in and near Japan. We recently obtained a strobila of this cestode that was excreted from a harbor porpoise accidentally caught offshore of Hokkaido of northern Japan. Genetic analysis of 28S rDNA andcox1genes confirmed that the cestode wasD. stemmacephalum. Our finding sets the northernmost record ofD. stemmacephalumin the western Pacific, suggesting that the risk of human infections by this parasite in northern Japan deserves further attention.
