肝吸虫(华支睾吸虫)分布甚广,几乎遍及全国。已知肝吸虫病流行区都是河网低洼地带,在那里的坑、塘、溪流中有豆螺、谈水鱼、虾等中间宿主孳生,加上当地居民有生吃或未烧熟而食鱼、虾的习惯,因此感染了肝吸虫。为了探讨囊蚴在鱼体分布与感染肝吸虫的关系,我们曾在潍坊地区观察了 4个县市淡水鱼体内肝吸虫囊蚴分布的情况,现将结果简报如后,供防病治病时参考。 Hydrothorax (Clonorchis sinensis) is widely distributed, almost all over the country. It is known that endemic areas of clonorchism are all low-lying areas of the river network where there are snails in pit, pond and stream, where intermediate hosts such as water fish and shrimp breed, and local residents eat raw or uncooked food Fish, shrimp habit, so infected with liver fluke. In order to investigate the relationship between the distribution of metacercaria and the infection of liver flukes, we have observed the distribution of larvae of larvae in four counties and cities in Weifang. The results are presented as follows for the prevention and treatment of diseases reference.
