Much of the vast evolutionary landscape occupied by Eukaryotes is dominated by protists. Though parasitism has arisen in many lineages, there are three main groups of parasitic protists of relevance to human and livestock health: the Apicomplexa, including the malaria parasite Plasmodium and coccidian pathogens of livestock such as Eimeria; the excavate flagellates, encompassing a diverse range of protist pathogens including trypanosomes, Leishmania, Giardia and Trichomonas; and the Amoebozoa, including pathogenic amoebae such as Entamoeba. These three groups represent separate, deep branches of the eukaryote tree, underlining their divergent evolutionary histories. Here, I explore what is known about sex in these three main groups of parasitic protists.
真核生物广阔的进化领域中，大部分都被原生生物占据。虽然寄生现象在许多谱系中都出现过，但与人类和家畜健康相关的主要寄生原生生物有三类：顶复门生物，包括疟原虫和家畜球虫病原体等艾美耳球虫；原生动物鞭毛虫，包括范围广泛的原生动物病原体，如锥虫、利什曼原虫、贾第虫和滴虫；肉足虫门，包括致病性阿米巴原虫，如溶组织内阿米巴。这三个群体代表了真核生物树的三个独立的、深的分支，突出了它们不同的进化历史。在这里，我探讨了这三类主要寄生原生生物中有关性别的已知情况。
