摘要: 寄生蠕虫群体遗传学研究常用的遗传标记有等位酶、线粒体DNA、随机扩增多态性DNA或扩增性片段长度多态性和微卫星DNA等。应用这些遗传标记的研究表明,大多数寄生蠕虫群体遗传结构有不同水平的变异,这些变异的产生主要与寄生虫的生活史和群体生态、宿主的地理分布和环境等因素有关,并因此提出了有关遗传变异的一些假说。本文对寄生蠕虫群体遗传学的研究作一综述。
Abstract:Genetic markers including allozyme,mtDNA,RAPD/RFLP and micro DNA have been used in the research of helminth population genetics.Available data on helminth genetic variability have shown that most helminth populations exhibit different levels of genetic variation resulting mainly from the pattern of life cycle,geographical distribution and parasite-host interaction,and several hypotheses have been proposed to explain the genetic variation.
