方法：从培养家蝇幼虫的猪粪中提取幼虫分泌物，制成虫卵培养液，观察培养液中猪蛔虫卵发育情况。
这项研究使用了300名马达加斯加的村民。蛔虫和恶性疟原虫都在这一地区流行。
大约一半的试验参与者服用了一种能把所有蛔虫都驱除的药物。
1·Conclusion Washing hands with toilet soap to keep hands clean can significantly reduce ascaris infection rate.
结论每日用香皂洗手保持手部清洁卫生，可以显著降低蛔虫感染率。
2·Objective To understand the reinfection status of Ascaris lumbricoides after different mass chemotherapy measures were implemented in heavily endemic areas with A.
目的了解蛔虫重度流行区采取不同方案的全民化疗措施后，居民个体和群体的蛔虫再感染状况。
3·Conclusion the Ascaris infection rate is influenced by mass chemotherapy, economics and health conditions in rural residents, especially the mass chemotherapy.
结论集体服药防治和经济卫生条件共同影响农村人群蛔虫感染率变化，尤其集体服药防治的作用更显著。
4·AIM: To study the dynamics of Ascaris infection in rural communities where intervention measurements were not introduced.
目的：了解未加控制措施干预下农村社区蛔虫感染与传播动态。
5·The highest infection rate of Ascaris and Trichuris was in the age group of 10-14 years, and a decrease tendency was revealed in those above 60 years old.
按年龄分析表明蛔虫和鞭虫感染率均以10—14岁年龄组为最高，60岁以上年龄组呈下降趋势。
