麦穗鱼(Psludorasbors parra)是华支睾吸虫最适宜的第二中间宿主。据易氏报告华支睾吸虫囊蚴感染率与感染度均随鱼体重增加而下降,为探明该现象作者1982～1991年在华支睾吸虫病流行区,定时定点作了连续观察,现报告于后。 观察方法:每年5月或10月捕麦穗鱼30尾以上,称重后用直接压片法计数华支睾吸虫囊蚴。按鱼体重分组统计分析。
Psludorasbors parra is the most suitable second intermediate host for Clonorchis sinensis. According to Yi reported Clonorchis sinensis metacercariae infection rate and infection were decreased with the increase in fish body weight, in order to explore the phenomenon of the author of 1982 to 1991 in the endemic area of Clonorchiasis sinensis, regular fixed point made a continuous observation, and now Report later. Observations: Each year in May or October to catch more than 30 wheat spikes, weighing, after direct compression method count Clonorchis sinensis metacercariae. According to fish weight grouping statistical analysis.
