目的:调查人囊型包虫病(CE)在蒙古布尔根地区和中国西北新疆的两个社区发病率.方法:于1995/2000年期间对布尔根(蒙古)及和布克赛尔(中国新疆)的两个民族构成类似的社区开展调查.结果:人囊型肝包虫病在两个社区的发病率有显著不同.在和布克赛尔超声诊断率为2.7%(49/1844).在布尔根超声诊断率为0.2%(4/1609)(P<0.01).对狗的研究显示两地棘球蚴抗体阳性和蠕虫感染率类似,即和布克赛尔为35.0%,布尔根为35.7%.对可能影响两地不同患病率的相关危险因素的研究发现:和布克赛尔牧民及农民所占的比例(48.5%)要显著高于布尔根(9.6%).在饲养狗和牲畜的比例方面,和布克赛尔(56%)也要显著高于布尔根(25%～27%).家庭屠宰牲畜的比例和布克赛尔(78.9%)同样显著高于布尔根(28.1%).结论:蒙古布尔根地区人囊性棘球蚴病感染率低的原因,与两地饲养狗的比例有关.
OBJECTIVE: To investigate the prevalence of human cystic echinococcosis (CE) in two communities in Burqin, Mongolia and Xinjiang in northwestern China.METHODS: The clinical data of Burkine (Mongolia) and Hexoksel (China Xinjiang) were investigated in similar communities.Results: The incidence rates of human cystic echinococcosis in two communities were significantly different.The diagnostic rates of ultrasound in Hezekoxel were 2.7% (49/1844) . The diagnostic rate of ultrasound in Burgen was 0.2% (4/1609) (P <0.01) .Research on dogs showed that the positive rate of echinococcosis and the rate of worm infection were similar between the two countries, ie, 35.0% with Boozel, The study found that the proportion of herders and peasants (48.5%) was significantly higher than that of Burgen (9.6%). In terms of the ratio of dogs and livestock raised, the rate of slaughtering livestock and that of Buxcel (78.9%) was also significantly higher than that of Burkase (56%) and Burk (25.9% Burgen (28.1%) .Conclusion: The low prevalence of human cystic echinococcosis in the Burgen region of Mongolia is related to the proportion of dogs kept in both places.
