目的了解广西横县野生鱼类吸虫囊蚴感染情况.方法从横县旺天塘水库采集常见的小型野生鱼类,用肌肉压片法和消化法检测吸虫囊蚴,根据囊蚴形态、排泄囊结构和囊壁厚度等特征区分吸虫的种类.结果检查490尾鱼,共查到4种鱼源性吸虫囊蚴,分别是华支睾吸虫、台湾棘带吸虫、棘隙吸虫和台湾次睾吸虫,感染率依次为43.88％、1.84％、1.84％和0.61％.华支睾吸虫囊蚴寄生于尾鳍基部的概率高于其他部位.结论横县野生鱼类的鱼源性吸虫感染严重,其中华支睾吸虫感染率最高,鱼尾鳍基部寄生的囊蚴最多.

Objective To investigate the infection status of wild fish with trematode metacercariae in Heng county of Guangxi.Methods Wild freshwater fishes were caught from WangTianTang reservoir in Heng.county and their metacercariael infections were examined by muscle compression and digestion technique.The species of metacercariae was identified through morphology characters:the shape of excretory bladder and thickness of cyst wall Results A total of 490 freshwater fish were collected,among which four species of metacercariae,Clonorchis sinensis,Centrocestus formosanus,Echinochasmus sp.and Metorchis taiwanensis were detected and the infection rate were 43.88％,1.84％,1.84％ and 0.61％ respectively.The fish tail fin has higher probability of being parasited by Clonorchis sinensis than nape and back.Conclusion Fish born trematodes,especially Clonorchis sinensis,have high prevalence in the wild freshwater fish in Heng county of Guangxi,the metacercariae mostly parasitize in the joint between muscle and fin especially the tail fin.
