虽然在红内期、红外期或蚊体阶段寄生的原虫的结构有很多差异,但某些结构相似之处却是明显易见的。这些寄生虫的详细超微结构是偶然发现的。它们出现在一特殊阶段,这就需引起这样的推测,即相同的细胞器也存在于生活史的其它阶段。这一回顾的目的在于使读者了解各个具体阶段其细胞器的一般慨貌,而与此同时,又要认识到孤立地详述它们几乎是不可能的。 Although there are many differences in the structure of protozoans parasitized in the red, infrared or mosquito stages, some structural similarities are evident. The detailed ultrastructure of these parasites was discovered by chance. They appear in a particular phase, which requires the speculation that the same organelles also exist in other phases of life history. The purpose of this review is to give the reader an idea of ​​the general appearances of its organelles at various stages, while at the same time recognizing that it is almost impossible to elaborate on them in isolation.
