目的为了解和分析新疆人体肠道寄生原虫流行现状和态势,评估10多年来的防治成效,为制订防治计划提供科学依据。方法碘液涂片、直接镜检方法;通过对溶组织内阿米巴、蓝氏贾第鞭毛虫和牙囊原虫的地区、性别、年龄、民族、职业和文化程度分布作了描述,对其流行因素进行分析。结果对新疆5个县(市)15个点6 750人进行了人体肠道原虫检测,受检率为90%(6 750/7 500),总感染率11.54%,较1991年调查感染率下降了59.03%。本次调查共查见肠道原虫11种,包括溶组织内阿米巴、蓝氏贾第鞭毛虫、结肠小袋纤毛虫、结肠内阿米巴、布氏嗜碘阿米巴、哈门氏内阿米巴、微小内蜓阿米巴、迈氏唇鞭毛虫、人牙囊原虫、肠内滴虫和人牛孢子虫,其感染率分别是0.34%,3.94%,0.87%,4.50%1,.19%0,.36%0,.43%,0.61%1,.30%,1.11%和0.61%。结论肠道原虫感染与饮用水源有关,今后应采取合理的防治措施控制新疆人体肠道原虫的流行。 Objective To understand and analyze the prevalence and trend of intestinal parasitic protozoa in Xinjiang and evaluate the effectiveness of control over more than 10 years so as to provide a scientific basis for formulating prevention and control plans. Methods Iodine smear and direct microscopic examination were carried out. The distribution of E. histolytica, B. pyogenes and C. albicans were described by their regions, sex, age, ethnicity, occupation and educational level. Pop factors for analysis. Results Human intestinal protozoa were detected in 15 spots and 6 750 in 5 counties and cities of Xinjiang. The detection rate was 90% (6 750/7 500), the total infection rate was 11.54%, which was lower than that of the survey in 1991 59.03%. In total, 11 species of enteric protozoa were found in this survey, including Entamoeba histolytica, Giardia lamblia, Colibacillary ciliate, Entamoeba histolytica, Amoxicillin amiodarum, The infection rates of amebiasis, Ameba, Mycosphaeria jannaschii, Cryptococcus albidus, Trichomonas and Enterobacter cloacae were 0.34%, 3.94%, 0.87%, 4.50% .19% 0, .36% 0, .43%, 0.61% 1, .30%, 1.11% and 0.61%. Conclusion The infection of intestinal protozoa is related to drinking water sources. In the future, reasonable prevention and control measures should be taken to control the prevalence of intestinal protozoa in Xinjiang.
