二叶虫病是一种传染病,是由食用含有广泛的in虫(二叶虫)幼虫的原始淡水或海鱼引起的。在本研究中,我们严格审查了台湾报告的所有人类双叶性关节炎病例,包括台北医院未发表的报道。基于线粒体DNA标记(cox1)的基因分型证实,最近的两例病例是由日本双头鱼引起的,它不是台湾原产的,可能是进口的太平洋鲑鱼感染了日本黄牛幼虫。先前在台湾报告的致病物种无法得到明确确认。然而,考虑到双头鱼的分布,这在台湾不是地方病,过去诊断为D.latus的病例值得怀疑。
Diphyllobothriosis is an infectious disease caused by the consumption of raw freshwater or marine fish containing larvae of broad tapeworms (Diphyllobothriidae). In the present study, we critically reviewed all cases of human diphyllobothriosis reported from Taiwan, including unpublished reports from hospitals in Taipei. Genotyping based on mitochondrial DNA marker (
cox1) confirmed that two of the recent cases were caused by Dibothriocephalus nihonkaiensis, which is not native to Taiwan and was probably imported with Pacific salmon infected with larvae of D. nihonkaiensis. The causative species previously reported in Taiwan could not be definitively confirmed. However, considering the distribution of Dibothriocephalus latus, which is not endemic in Taiwan, past cases diagnosed as D. latus are questionable.
