都匀市农村土源性线虫病调查分析

The Survey Analysis of Rural Soil Source Sex Nematode in Areas of Duyun City

目的:对农村土源性线虫病连续两年进行流行病学调查与监测,比较农村线虫病感染状况,了解影响其流行因素,为更好地进行科学防治提供依据。方法:对粪便样本采用改良加藤厚涂片法进行蛔虫、钩虫、鞭虫卵镜检计数和牛皮纸方形孔胶带纸粘贴法进行蛲虫卵镜检计数,土壤样本用改良饱和硝酸钠漂浮法进行蛔虫卵镜检计数。结果:2013、2014年度监测点居民、土壤感染率分别为24.6%(123/500)、9.2%(46/500),40.0%(16/40)、22.5%(9/40)。结论:土源性线虫病感染率有明显下降,但还应加强环境卫生整治,净化水源,改善垃圾处理;改变群众卫生习惯,加强群众自我防病意识;普及宣传,群防群治,综合治理。

Objective： To understand the impact of the epidemic factor and in order to better provide the basis for scientific prevention and control , and comparison of rural infection of nematode disease for the soil source rural nematode disease in two consecutive years to epidemiology and surveillance.Method： Fecal samples were used a modified Kato Inori to count by microscopy for ascaris, hookworm, trichuris trichiura eggs and kraft paper adhesive tape sticked method of square hole for pinworm eggs counted by microscopy , and the soil samples by a modified saturated sodium nitrate floated method for ascaris eggs were counted by microscopy. Result： Residents of monitoring points and the soil infection rates of 2013 year and 2014 year respectively were 24.6% （ 123/500 ）, 9.2% （ 46/500 ） and 40.0 （ 16/40 ）, 22.5% （ 9/40 ） .Conclusion： Soil borne nematode infection rate decreased obviously. There are should strengthen the sanitation, water purification, improve waste disposal, and change the masses health habit, strengthen the people＇s self consciousness of disease control, and popularization, mass prevention, comprehensive management.
