摘　　要：目的掌握云南省勐海县西定乡人群土源性线虫感染情况,为制定土源性线虫病防治策略提供依据。方法采用改良加藤厚涂片法检查粪便中土源性线虫卵,透明胶纸肛拭法检查儿童蛲虫卵。随机抽取15户居民,每户采集蔬菜、水果或其他作物种植地的土样进行钩蚴分离。结果共粪检1 002人,土源性线虫感染率为20.06%(201例),其中钩虫、蛔虫和鞭虫感染率分别为18.96%(190例)、1.70%(17例)和0.90%(9例)。钩虫、蛔虫和鞭虫感染者中,轻度感染者分别占97.37%(185/190)、88.24%(15/17)和100%(9/9)。未检出蛲虫感染者。检测土壤15份,未检出钩蚴。结论勐海县西定乡居民土源性线虫感染率较高,但感染度低。应加强该地区土源性线虫病的防治与监测。Objective To understand the status of soil-transmitted nematode infections in Xiding Township, Menghai County, Yunnan Province, so as to provide the reference for formulating the strategy of soil-transmitted nematodosis control. Methods Soil-transmitted nematode eggs in feces were detected by the Kato-Katz method, and the eggs of Enterobius vermicularis were detected by the cellophane tape method in children. The soil samples were collected from vegetable, fruit and other crop fields of 15 residents randomly to detect hookworm. Results The stool samples from 1 002 residents were examined and the soil -transmitted nematode infection rate was 20.06% （201/1 002）. The infection rates of hookworm, Ascaris lumbricoides and Trichuris trichura were 18.96% （190 cases）, 1.70% （17 cases） and 0.90% （9 cases） respectively. The percentages of people with light infection of hookworm, A. lumbrieoides and T. trichura were 97.37% （185/190）, 88.24% （15/17） and 100% （9/9） respectively. No infection of E. vermicularis was found. Fifteen soil samples were tested, and no hookworm was found in the soil. Conclusion The infection rate of soil-transmitted nematode in Xiding Township, Menghai County is high, but the infectiosity is light. The control and monitoring of soil-transmitted nematodosis should be strengthened in this area.
