摘要 

复口吸虫是淡水鱼类的一种常见的寄生虫,在欧洲、亚洲和北美等地区均有复口吸虫的分布。复口吸虫的生活史是一个复杂过程,分别经过虫卵、毛蚴、胞蚴、尾蚴、后囊蚴和成虫阶段,其中间寄主分别为第一中间寄主螺、第二中间寄主鱼和终末寄主鸟。在自然水体里,特别是在人工养殖水体中,复口吸虫具有明显的致病性,能使第二中间寄主鱼产生一系列的病症,严重的能引起寄主鱼的大量死亡。科学家对其的研究比较深入和广泛,而本文仅对复口吸虫的分类学、生活史、流行病学和致病机理的研究进展进行介绍。

Abstract

Eyeflukes of the genus Diplostomum are the common parasite of freshwater fishes,and these parasites are widely distributed in the world such as Europe, Asia and North American. The life cycle of Diplostomum is a complicated process including Egg, Miracidium, Sporocyst, Cercaria, Metacercaria and Adult. The eyeflukes the genus Diplostomum invade and establish three distinct host species that were the first intermediate host snails, the second intermediate host fish, the definitive host gull, respectively. In natural water, particularly in aquacultural farms operating intensive monoculture systems, these parasites can be significant pathogens causing a range of disease symptoms, which may lead to high of fish mortality. The aspects of the taxology, life-cycle, epidemiology and pathogenesis of Diplostomum, as well as the advance studies of Diplostomum were discussed in this paper.
