锥虫系统发育的研究进展

锥虫(trypanosome)是最早在鱼类血液中发现、随后在几乎所有的脊椎动物血液里都有发现的原生动物寄生虫。它主要通过水蛭和吸血昆虫传播,使宿主受到不同程度的危害。为了较全面地了解锥虫系统发育的研究进展,本文综述了国内外有关锥虫系统发育研究的四个方面的内容锥虫的起源(介绍了锥虫起源于脊椎动物和起源于无脊椎动物的两种不同观点);锥虫的系统发育方式(单系发育);锥虫的进化是否与寄主存在协同性及进化史上分歧时间的差异性;目前研究中存在的问题。

Progress of Phylogeny in Trypanosomes

Protozoan flagellates of the genus Trypanosoma are first found in fish, subsequently found in almost all classes of vertebrates and transmitted from host to host by blood-sucking arthropod or leech vectors. They are harmful to host. Based on the data of phylogeny in trypanosome, the origin, phylogeny and evolution of trypanosome, coevolution between host and trypanosome parasite, and present existing problems were reviewed in this article.
