摘　　要：对从锦鲤(Cyprinus carpio)分离出的多子小瓜虫(Ichthyophthirius multifiliis)采用离体单克隆培养,选用硫酸铜和硫酸亚铁合剂(5∶2)、高锰酸钾溶液及福尔马林,3种化学药物探究其对多子小瓜虫的致死情况。结果表明:3种药物浓度均与多子小瓜虫的死亡率存在正相关趋势,且5.6 mg/L的硫酸铜和硫酸亚铁合剂、8 mg/L的高锰酸钾溶液、120 mg/L的福尔马林都能全部致死多子小瓜虫;多子小瓜虫对3种化学药物的敏感性为:硫酸铜、硫酸亚铁合剂>高锰酸钾溶液>福尔马林。研究结果在一定程度为小瓜虫病的治疗及预防提供相应的数据支持和试验基础。In this study, Ichthyophthirius multifiliis isolated from Cyprinus carpio was in vitro monoclonal culture, using mixture of copper sulfate and ferrous sulfate(5∶2), aqueous solution of potassium permanganate and formalin to explore the mortality to Ichthyophthirius multifiliis. The results showed that the concentration of the three drugs is positively correlated with the mortality of Ichthyophthirius multifiliis, and 5.6 mg/L of copper sulfate and ferrous sulfate mixture, 8 mg/L potassium permanganate aqueous solution and 120 mg/L formalin can kill all of the Ichthyophthirius multifiliis. The sensitivity of the Ichthyophthirius multifiliis to these three chemical drugs: Copper sulfate and Ferrous sulfate mixture>Potassium permanganate aqueous solution>Formalin. The research results provide corresponding theoretical data and experimental basis for the treatment and prevention of Ichthyophthirius multifiliis disease to a certain extent.
