目的分析江苏省土源性线虫病监测点2006-2010年土源性线虫感染率及变化情况.方法 2006-2010年在江苏省宿迁市沭阳县胡集镇华集村设立国家土源性线虫病监测点,同时在全省其他地区设立省、市级监测点83个.每年秋季收集3岁以上的常住居民(1000人以上)粪便,采用改良加藤厚涂片法粪检肠道蠕虫卵.在沭阳县监测点,随机选择送检的10户家庭,采集其居所附近的菜地、厕所周边、庭院和厨房等4种环境类型的土壤各1份,用改良饱和硝酸钠漂浮法检测蛔虫卵污染情况；对参检的3～12周岁儿童用透明胶纸肛拭法加检蛲虫卵.在其他监测点,抽查幼儿园儿童和小学低年级学生,用透明胶纸肛拭法检查蛲虫卵.结果沭阳县监测点居民土源性线虫感染率和儿童蛲虫感染率均呈下降趋势,从2006年的1.81％(19/1049)和4.72％ (5/106)分别下降至2010年的1.23％(13/1061)和0(0/90),分别下降32.04％和100％；其他监测点居民土源性线虫和儿童蛲虫感染率也呈下降趋势,2006年分别为2.61％ (2547/97405)和2.42％(3187/131 965),2010年分别为0.84％(900/107 233)和0.95％(1015/106 959),分别下降67.82％和60.74％.所有感染者均为轻度感染；检测50户家庭不同环境类型的土壤200份,未发现蛔虫卵.结论 2006-2010年江苏省人群土源性线虫和儿童蛲虫感染率呈下降趋势,处于较低流行水平.

Objective Objective To analyze the prevalent trend of soil-transmitted nematode infections at the surveillance sites in Jiangsu Province from 2006 to 2010.Methods The national surveillance site of soil-transmitted nematode infections was located in Huaji village of Shuyang County in Suqian City.There were eighty three provincial and municipal level surveillance sites.From 2006 to 2010,fecal samples of the residents of 3 years old and above were collected in every autumn and the intestinal helminth eggs were examined with the modified Kato-Katz thick smear technique.Soil samples which were also collected from vegetable fields,lavatory,courtyard and kitchen of 10 randomly selected families with stool egg-positive,were examined for Ascaris eggs by a modified saturated sodium nitrate floated method.Cellophane tapes were applied to detect pinworm eggs for children aged 3-12 years old.Results The infection rates of soil-transmitted nematode in residents and pinworm in children at the Shuyang County surveillance sites reduced from 1.81％(19/1049) and 4.72％ (5/106) in 2006 to 1.23％ (13/1061) and 0(0/90) in 2010 respectively,and infection rates of soil-transmitted nematode and pinworm decreased 32.04％ and 100％ respectively.The infection rates of soil-transmitted nematode in residents and pinworm in children also showed a downtrend in other surveillance sites,from 2.61％ (2547/97405) and 2.42％ (3187/131 965) in 2006 to 0.84％ (900/107 233) and 0.95％ (1 015/106 959) in 2010 respectively,The infection rate of soil-transmitted nematode and pinworm decreased 67.82％ and 60.74％ respectively.The infection intensity in all infected people was light.None of Ascaris eggs was found in all 200 soil samples from 50 families.Conclusion The infection rates of soil-transmitted nematode in residents and pinworm in children showed a decreased trend and kept a low level of prevalence in Jiangsu Province during 2006-2010.
