摘要
目的了解甘肃省农村居民生活环境中人蛔虫卵污染的现状。方法分别采集武山县、凉州区、岷县3个调查点10～20户居民4类环境中的土壤，应用饱和硝酸钠漂浮镜检法检查土样中人蛔虫卵，计算土壤样品的蛔虫卵阳性检出率，并对3地居民蛔虫感染率进行分析比较。结果土壤中人蛔虫卵总检出率为28％，菜园、厕所周边、庭院、厨房土壤的人蛔虫卵检出率依次为30％、36％、30％和16％。结论调查点环境蛔虫卵污染严重，应采取措施改善环境卫生，减少居民感染蛔虫。
Objective To investigate the different soil contamination of Ascaris lumbricoides eggs at living environments in rural areas. Methods Wushan County, Liangzhou District and Min County were selected as 3 pilots for investigation. Ten samples of soil including 4 different environments from Min County and 20 samples from the others were randomly collected. A. lumbricoides eggs in the different soil were floated with saturated nitrate and counted by microscopy. Positive rate of A. lumbricoides eggs in the soils was then calculated and A. lumbricoides infection rates of inhabitants at 3 pilots were compared and analysed. Results The overall positive rate of A. lumbricoides eggs in the soils was 28%, and among them the rates at the vegetable gardens, lavatory surroundings, courtyards in the countryside and kitchens were 30% ,36% ,30% and 16% , respectively. Conclusion The pilots were badly contaminated by A. lumbricoides eggs. Measures should be taken to improve the living environments and decrease the infection rate of Ascaris in the residents.
