目的 目的 了解景洪市拉祜族居民肠道寄生虫感染情况， 为科学防治提供依据。方法 方法 在景洪市小街乡曼先坦村抽 取3个自然村， 采用改良加藤法检测土源性线虫卵， 开展问卷调查并分析居民卫生行为和卫生习惯与肠道寄生虫感染的关 系。结果 结果 对289人进行粪检， 土源性线虫感染255例， 感染率为88.24%。其中钩虫感染210例， 感染率为72.26%； 蛔虫感 染154例， 感染率为53.29%； 鞭虫感染13例， 感染率为4.50%； 其他寄生虫感染16例， 感染率为5.54%。钩虫、 蛔虫和鞭虫轻 度感染者分别占90.48%、 97.40%和100%。结论 结论 景洪市拉祜族居民土源性线虫感染率极高， 但感染度低。应加强该地区 土源性线虫病的防治与监测。

Investigation of prevalence of soil-transmitted nematode infections among Lahu Ethnic residents in Xiaojie Township,Jinghong City,Yunnan Province

Objective To understand the current state of staff for Plasmodium microscopy examinations in Changzhou City in the early stage of eliminating malaria action, so as to provide the evidence for achieving the target of malaria elimination. Methods The staff for Plasmodium microscopy examinations from medical institutions and centers for disease control and prevention at differ ent levels were investigated by questionnaires and tests of the malaria related theory and microscopic operation. Results Totally 95 people were investigated, and among them, 40.0% had college degree and 45.3% were university educated. There were 18.9% of them working on Plasmodium microscopy examinations for less than 1 year, 40.0% for 2-5 years, 18.9% for 6-10 years and 22.1% for more than 10 years. The numbers of person-time of provincial and municipal level training, district-level training, and unit-level training in the last year were 0.57, 0.59, and 0.14, respectively. Totally 18.9% of them had the experience of finding Plasmodium at work, and 97.9% of them considered it was necessary or very necessary to do Plasmodium microscopy examina tions. However, 57.9% and 8.4% of them considered Plasmodium microscopy examinations increased their work load and work dif ficulty, respectively. The average correct rates of knowledge tests on malaria before and after training were 72.5% and 91.6% re spectively （P 〈 0.05）. The average mark of Plasmodium microscopic tests was 25.3 points （full mark being 50 points）, and the passing rate （≥30 points） was 58.9%. Conclusion The working experience of staff for Plasmodium microscopy examinations in Changzhou City is relatively poor, and the related training should be enhanced.
