1 材料与方法在江苏省兴化市荻垛乡西茆村对1周岁以上居民进行粪检,共对比检查161人。每份粪样分别作直接涂片(取粪约5mg),Kato-Katz法(定量板取粪41.7mg,常规检查1片),饱和盐水浮聚法(金属圈取粪样500mg,镜检1片)和钩蚴培养法(试管滤纸法)检查,发现虫卵和钩虫幼虫判为阳性。Ka-to’s法作定量计算,每片虫卵数乘以23.98即为克粪虫卵数(EPG)。 2 结果肠道线虫总感染率为81.4％(131/161)。其中蛔虫、钩虫、鞭虫的感染率分别为52.2％(84/161)、59.0％(95/161)、21.1％(34/161)。平均EPG MATERIALS AND METHODS Semen tests were carried out for residents over the age of 1 in Xijiao Village, Digu Township, Xinghua City, Jiangsu Province, for a total of 161 people. Each stool samples were directly smear (take feces about 5mg), Kato-Katz method (quantitative plate take feces 41.7mg routine inspection 1), saturated saline floating method (metal ring taking fecal sample 500mg, microscopy 1 ) And the method of in vitro culture (test tube filter paper), the eggs and hookworm larvae found to be positive. Ka-to’s method for quantitative calculation, the number of eggs per piece multiplied by 23.98 is the number of grams of eggs per gram of food (EPG). 2 Results The total infection rate of intestinal nematodes was 81.4% (131/161). The infection rates of roundworm, hookworm and whipworm were 52.2% (84/161), 59.0% (95/161) and 21.1% (34/161), respectively. Average EPG
