利用随机扩增多态性片段DNA技术 (RAPD)对黑龙江、新疆、贵州、四川、甘肃和云南寄生于鲤鱼的头槽绦虫以及广东、广西、福建和贵州寄生于草鱼的头槽绦虫进行了多态性分析。结果显示 :我国寄生于鲤鱼、草鱼的头槽绦虫种群内部变异程度较高 ,大致分为两个类群 ,即寄生于草鱼的头槽绦虫和寄生于鲤鱼的头槽绦虫 ,其分布呈现明显的地理区域性 ,主要分布于不同的南北水系中。草鱼头槽绦虫又可分为 2个亚类 :珠江水系头槽绦虫和贵州地区头槽绦虫 ;鲤鱼头槽绦虫可分为 2个亚类 :长江水系头槽绦虫和黄河水系头槽绦虫。同时还找到了区分草鱼、鲤鱼头槽绦虫的特异带型。这一结果使我国不同地区草鱼、鲤鱼头槽绦虫的亲缘关系得到了进一步的阐明
In this study, we used the random amplified polymorphic DNA (RAPD) technique to screen for C. cepaciae parasitized in common carp in Heilongjiang, Xinjiang, Guizhou, Sichuan, Gansu and Yunnan provinces, and in southern China, Guangdong, Guangxi, Fujian and Guizhou Analysis of the state. The results showed that there was a high degree of internal variation in cephalosporins of parasitoid Cyprinus carpio and grass carp in our country, which were broadly divided into two groups, that is, cephalopod parasitized in grass carp and cephalopod parasitized in common carp. Regional, mainly in different north-south water system. Grass carp Tau slotted tapeworm can be divided into two sub-categories: the Pearl River water head trough tapeworm and Guizhou head trough tapeworms; carp Tau groove tapeworm can be divided into two sub-categories: the Yangtze River water flume and the Yellow River head flume tapeworm. At the same time also found a distinction between grass carp, carp Tau slotted tapeworm specific band. This result has further elucidated the genetic relationship between grass carp and carp head carcasses in different areas in China
