淡水鱼虾华支睾吸虫囊蚴感染情况调查

采集吉林省白城地区镇赉县周边6个鱼塘的各种鱼类,用直接压片镜检法和人工消化法分别对采集回来的麦穗鱼感染华支睾吸虫囊蚴的情况进行统计调查,结果表明,感染率最高、感染强度最大的鱼塘是四方坨六分场。随即对四方坨六分场鱼塘中各种鱼类华支睾吸虫囊蚴感染情况也采用同样方法进行调查,结果显示,感染率最高的是麦穗鱼、银飘鱼、尖头鱥,均为100%;其次是细鳞鱼,为80%;其他种类的鱼虾均未检测到有华支睾吸虫囊蚴寄生。

Epidemiological Study on Clonorchis sinensis Metacercarias Infection of Freshwater Fish and Shrimp

Pseudorasbora parva collected from six fishponds around Zhenlai county, Baicheng area in Jilin province were examined for metacercaria (Clonorchis sinensis) by the methods of direct pressing slice and artificial digestion in order to carry out statistical survey for infective rate of metacercaria of Pseudorasbora parva. The highest infection rate and strongest infective intensity area of freshwater fishes with metacercariae was the sixth field of Sifangtuo. Subsequently, investigating all kinds of fishes of the strongest infective intensity area to learn information of infection of metacercaria. The results displayed the highest infective rate were 100% in Pseudorasbora parva, Pseudolaubuca sinensis and Phoxinus oxycephalus, then was 80% in Brachymystax Lenok.
