摘要
不同种的锥虫属原生动物外观相似（图1），并且都被称作“动基体质体目原生动物”，因为他们利用一种被叫做质体的线粒体获得能量进行鞭毛运动。但锥体虫也在许多方面各有所不同，包括他们的分子和细胞生物学、传播及所致疾病等方面。
Different species of the protozoan Trypanosorna are of similar appearance （Figure 1）, and all are termed ＇kinetoplastids＇ because they move using a flagellum that obtains energy from a mitochondrion called a plastid. However, trypanosomes also differ in many ways, including aspects of their molecular and cellular biology, their transmission, and the diseases that they canse.
