目的探索荣宝杀灭野粪中血吸虫卵和氯硝柳胺展膜剂杀水体中毛(尾)蚴控制传染源和阻断传播途径的效果。方法水淹有螺洲滩前,每15 d用50%荣宝处理外洲野粪(粪:药=100g:3g)和1%氯硝柳胺展膜剂(3ml/m~2)处理水体毛(尾)蚴。结果干预前,长江和洞庭湖洲滩野粪阳性率分别2.22%和10.23%,感染螺平均密度0.0208和0.041 7只/0.11m~2,哨鼠感染率11.11%,2012年对照组哨鼠感染率50%;干预后野粪阳性率显著下降,差异有统计学意义(x~2=3.64,P<0.05),感染螺平均密度和哨鼠感染率均下降至0。结论联合使用荣宝处理洲滩野粪和氯硝柳胺展膜剂杀灭水体中毛(尾)蚴,具有早期控制血吸虫病传染源和阻断传播途径的作用。
Objective To explore the effect of Rongbao in killing schistosome eggs in schistosomiasis and controlling the source of infection and blocking the route of transmission in the water body of schistosoma japonicum. Methods Water was treated with 50% rongbao to treat water (3x / m ~ 2) of alfalfa manure (dung: medicine = 100g: 3g) and 1% niclosamide enveloping agent Body hair (tail) larvae. Results Before the intervention, the positive rates of stool in the Yangtze River and Dongting Lake were respectively 2.22% and 10.23%, the average infection density was 0.0208 and 0.041 7 /0.11m ~ 2, and the infection rate in sentinel mice was 11.11%. In the control group, (50%). After the intervention, the positive rate of stool decreased significantly, the difference was statistically significant (x ~ 2 = 3.64, P <0.05). Conclusions The combination of Rongbao treatment of hantan truncatus and niclosamide film-forming agent to kill hairy (larva) larvae in water has the effect of controlling the source of schistosomiasis in the early stage and blocking the transmission route.
