摘要
利川锥虫（ＴｒｙｐａｎｏｓｏｍａｌｉｃｈｕａｎｅｎｓｉｓＬｉ）寄生在棘腹蛙血液内。虫体波动膜明显。鞭毛较粗，一般不伸出体外形成游离的鞭毛。感染试验表明其中间宿主是绿蛙蛭（ＢａｔｒａｃｏｂｄｅｌｌａｐａｌｕｄｏｓａＣａｒｅｎａ）。虫体在绿蛙蛭嗉囊的上皮细胞内进行裂配生殖或假包囊，产生许多无鞭体、前鞭体和锥虫体等不同发育时期。前鞭体的超微结构特点是：虫体表膜较厚，表膜下微管管壁较厚，线粒体较多，卵圆或长椭圆形，隆嵴不明显。未见高尔基体，内质网很少，不易观察到。胞质中有３—５颗或更多、多角形至圆形，较大的色素体。
Trypanosoma lichuanensis Li parasitic in the blood of Rana boulengeri possesses a thick flagellum and a notable undulating membrane. Free flagellum was not observed at the anterior end of the body. Laboratory experiments revealed that the intermediate host of this parasite is a small leech, Batrachobdella paludosa Carena. Amastigotes, epimastigotes and trypomastigotes were produced by schizogony or pseudocyst in leech's crops. The epimastigotes are characteristic of thick pellicle and thick wall of subpellicular microtubules, and of many mitochondria which are oval or elongated ellipsoidal in shape and are indistinct in ridges. Their rough endoplasmic reticula were few with 3-5 or even more round or pigment granules in cytoplasm.
