肠线虫感染病原检查优化方案的研究

Advantageous plan for detecting patients infected with intestinal nematoda

目的 探究肠线虫感染人群病原检查优化方案。方法 比较分析定量透明法、饱和盐水浮聚法和钩蚴试管滤纸培养法对不同感染率、感染度肠线虫卵检出效果。应用指数曲线拟合法分析定量透明法的检漏规律。结果 定量透明法检查蛔、钩、鞭虫卵存在检漏 ,且检查钩、鞭虫卵的检漏率 (EPG <2 5时 ,检漏率分别达 80 8%和 6 4 5 % )与感染度成反比。结论 在低感染度人群普查或防治效果考核中应选用定量透明法并用饱和盐水浮聚法。

Aim To Study the advantageous plan for detecting patients infected with intestinal nematoda Methods Adopting the way of quantitative transparent thick smear,saturated brine floatation and test tube filter paper culture to comparatively observe the effect on examination of patients infected with intestinal nematoda Adopting the method of exponential curve to analyse the observe law with quantitative transparent thick smear Results There was omittance in detecting eggs of ascaris,hookworm and whipworm by adopting quantitative transparent thick smear Below 25 EPG (eggs pre gram) of hookworm and whipworm,the omitting rates were 80 8% and 64 5%,being inverse with degree of the infection Conclusion In detecting people with lower degree of infection of intestinal nematoda,the methods of quantitative transparent thick smear and saturated brine floatation must be used
