目的 探讨流动人口土源性线虫病的防治对策。方法 对来自全国 14个省的外来人员采用改良加藤法和试管滤纸培养法进行土源性线虫感染基线调查。结果 共检查外来人员 934人 ,查出土源性线虫感染者 10 3例 ,总感染率为 11.0 3% ,感染率在 2 0 %以上有 3个省。共查见土源性线虫4种 ,即蛔虫、钩虫、鞭虫和艾氏小杆线虫 ,其感染率分别为 3.0 0 %、7.6 0 %、1.2 8%和 0 .2 1% ;本次查检的艾氏小杆线虫为宁波市首次发现。结论 今后在流动人口土源性线虫病防治中 ,应选择一些对钩虫、鞭虫、蛔虫的成虫和虫卵都有杀灭作用的广谱驱虫药驱虫 ,从而达到控制土源性线虫的目的。
Objective To explore the control measures of soil-borne nematodes in floating population. Methods The baseline survey of soil-borne nematode infection was carried out by using the improved Kato method and the tube filter paper culture method for the migrants from 14 provinces in China. Results A total of 934 foreign workers were examined. Among them, 103 cases of soil-borne nematodes were found, with a total infection rate of 11.0%. There were 3 provinces with an infection rate of 20% or more. Four species of soil-borne nematodes, namely roundworm, hookworm, whipworm and clubs were found. The infection rates were 3.0%, 7.6%, 1.2% and 0.2% respectively. Ehrlichia for the first time found in Ningbo City. Conclusion In the future, some broad-spectrum deworming insecticides should be chosen to control the soil-borne nematode diseases of migratory population, such as hookworm, whipworm and roundworm, so as to control the soil-borne nematode purpose.
