为了解肇源县常见淡水鱼华支睾吸虫囊蚴的感染情况,试验采用直接压片法和消化法对肇源县12种常见淡水鱼华支睾吸虫囊蚴感染情况进行了调查。结果表明:在调查的510尾淡水鱼中,检出阳性鱼186条,感染率为36.47%,其中麦穗鱼、柳根鱼和船丁鱼的感染率分别为92.45%(98/106)、78.95%(15/19)和52.00%(13/25),未在鲈塘鳢、黄颡鱼和泥鳅体内检出华支睾吸虫囊蚴;麦穗鱼的感染强度最高,达到88个/g。说明肇源县淡水鱼华支睾吸虫囊蚴感染率高、感染强度大,在该地区生食或吃未煮熟的淡水鱼感染华支睾吸虫的风险较高。
In order to understand the infection of Clonorchis sinensis, a common freshwater fish in Zhaoyuan County, we investigated the infection of Clonorchis sinensis in 12 species of freshwater fish in Zhaoyuan County by direct compression and digestion. The results showed that among the 510 freshwater fish surveyed, 186 positive samples were detected, the infection rate was 36.47%. The infection rates were 92.45% (98/106), 78.95 % (15/19) and 52.00% (13/25) respectively. However, the metacercaria of C. sinensis was not detected in the seabream, the yellow catfish and the loach. The infected fish had the highest infection intensity of 88 / g. Description Zhaoyuan County, freshwater fish Clonorchis sinensis metacercariae infection rate is high, the intensity of infection, in the area of raw food or eating uncooked freshwater fish infected with Clonorchis sinensis higher risk.
