Abstract

Fasciolopsiasis caused by Fasciolopsis buski, is a significant cause of morbidity. In the present study F. buski detected during endoscopy of a 50-year-old male patient form Uttar Pradesh, India was used for phylogenetic analysis based on 28S rDNA and ITS2 regions. The parasite was genetically similar to an isolate of pig from Meghalaya. The intra-species genetic variation for 28S rDNA was 1–3% (India), 5% (Vietnam) and for ITS2, 1–2% (India) while 17 % from Vietnam. Thus, F. buski from humans or pigs from India were closely related than those from Vietnam and China which were grouped into separate clades.

根据核核糖体 DNA 序列，从印度人类宿主中分离出的 Fasciolopsis buski 具有独特的支系。

由 Fasciolopsis buski 引起的鱼鳞病是发病的一个重要原因。本研究根据 28S rDNA 和 ITS2 区域对在印度北方邦一名 50 岁男性患者的内窥镜检查中检测到的 F. buski 进行了系统发育分析。该寄生虫在遗传学上与梅加拉亚邦的猪分离株相似。28S rDNA 的种内遗传变异为 1-3%（印度）和 5%（越南），ITS2 的种内遗传变异为 1-2%（印度）和 17%（越南）。因此，与越南和中国的F. buski相比，印度的人或猪与F. buski的亲缘关系更为密切，而越南和中国的F. buski则被划分为不同的支系。
