作者在冈比亚红土高原,对埃及血吸虫流行区内的螺类宿主用氯硝柳胺进行了3年(1976～1978年)的灭螺实验,同时作了儿童新感染率变化的观察,以评价杀螺剂的效果。方法:在6个村庄附近的10个池塘有螺地带用杀螺剂进行处理。同时以未处理池塘作为对照。将含有70%有效成分的可湿性氯硝柳胺粉剂,用池塘水混和,配成不超过1.5%浓度的药液由2人对这些池塘的主部和连接的沼泽地作均匀的喷洒,当遇到深水和边沿沼泽地时,放慢喷洒速度以增加药量。
On the Rhodiola Plateau in the Gambia, the snail host in the endemic area of Schistosoma japonicum was treated with niclosamide for three years (1976-1978), and the change of new infection rate in children was also evaluated. Spiral effect. Methods: Ten ponds in six villages with snails were treated with snail. At the same time as untreated pond as a control. The wettable niclosamide powder containing 70% of the active ingredient is mixed evenly with pond water and mixed to a concentration of not more than 1.5% by two persons to spray evenly on the main part of the pond and the connected marshes when When you encounter deep water and edge swamps, slow down the spray rate to increase the dose.
