| 本文结合野外调查数据和文献资料，报道了鱊头槽绦虫（Bothriocephalus acheilognathi）在我国感染的鱼类宿主种类及其地理分布。鱊头槽绦虫是一种世界性广布鱼类寄生绦虫；它起源于亚洲地区并伴随着宿主鱼类向外引种在世界范围内广泛扩散。在我国鱊头槽绦虫广泛分布于从北至南的自然水域或养殖水体中（辽河、海河、额尔齐斯河、伊犁河、黄河、淮河、长江、闽江、珠江等流域）；感染宿主鱼类达31种，其中鲤科（Cyprinidae）26种、鳢科（Channidae）1种、塘鳢科（Eleotridae）1种、慈鲷科（Cichlidae）1种、胎鳉科（Poeciliidae）2种。在调查的各水系野生鱼类中，马口鱼（Opsariichthys bidens）和赤眼鳟（Squaliobarbus curriculus）具有较高的感染率；各大流域池塘养殖的草鱼（Ctenopharyngodon idella）几乎都有鱊头槽绦虫的寄生。作者根据鱊头槽绦虫的流行特征认为马口鱼和赤眼鳟可能为该绦虫在自然水体中的主要宿主。 |

| The Asian Fish Tapeworm(Bothriocephalus acheilognathi Yamaguti, 1934) (Cestoda: Bothriocephalidea) is an important parasite of cultured carp, which has caused worldwide concern, due to its pathogenecity and wide distribution. It was commonly considered to be originated from East Asian, however, reports on its infected host range and distribution in China was limited. Based on authors field investigation and the previous records in literatures, this paper firstly present the detailed host range and distribution of B.acheilognathi in China. In the present research, tapeworms found were isolated from the host's intestine and rinsed in saline solution. Specimens used for morphological identification were fixed with hot (almost boiling) 4% formaldehyde solution, and permanent preparations were stained with iron hydrochloric carmine, destained in 70% acid ethanol, dehydrated in an alcohol series, cleared in clove oil and mounted in Canada balsam. The result revealed that B.acheilognathi occurred in almost all freshwater habitats from north to south China (Liaohe River, Haihe River, IrtySh River, Yili River, Yellow River, Huaihe River, Yangtze River, Min River, Pearl River), infected about 31 freshwater fishes, including 26 from Cyprinidae, 1 from Channidae, 1 from Eleotridae, 1 from Cichlidae and 2 from Poeciliidae. B.acheilognathi from wild fish Opsariichthys bidens and Squaliobarbus curriculus habiting in all Rivers present higher infection prevalence. Based on the epidemiologic characters and the population genetic variations, authors considered that fish O.bidens maybe the primary hosts of B.acheilognathi. As the wide geographic distribution and diverse host, B.acheilognathi represents an attractive model for studies on parasite host switch and speciation. Future research is required to enclose the genetic diversity of B.acheilognathi populations from different definitive hosts. |
