乌鲁木齐水西沟镇、托里乡细粒棘球蚴病血清流行病学调查

Seroepidemiological survey on echinococcosis in Shuixigou Town and Torre Township of Urumqi

目的 调查乌鲁木齐南郊农、牧区细粒棘球蚴病的流行现状。 方法 2009年4—6月，在乌鲁木齐县水西沟镇和托里乡，采用分层整群抽样方法各抽取2个有代表性村的常住居民，进行登记，并采集血液样本。采用间接ELISA法测定血清抗体。 结果 共调查4个村1 726人, 检出细粒棘球蚴病血清阳性者239人,总阳性率为13.8%（239/1 726）。其中水西沟镇（农区）为11.78%（92/781），托里乡（牧区）为15.56%（147/945），二者差异有统计学意义（χ2=5.110，P〈0.05）。不同性别、不同民族、不同年龄组的人群细粒棘球蚴病血清学的阳性率也不同。男性血清阳性率为10.17%（76/747），女性血清阳性率为16.65%（163/747）；哈萨克族人群血清阳性率最高，为14.83%（213/1 436）；回族次之，为10.96%（8/73），汉族最低，为6.72%（8/119）。30岁以上的劳动力人群血清阳性率较高。 结论 乌鲁木齐南郊农、牧区居民细粒棘球蚴病处于中度流行状态。

Objective To understand the present situation of antibody level against echinococcosis in agricultural and pastoral areas of Urumqi County. Methods Using the stratified cluster sampling, four villages in Shuixigou Town and Torre Township of Urumqi were picked up from April to June in 2009, the residents were registered and the blood samples were collected. The sera samples were tested by indirect ELISA. Results A total of 1 726 sera samples were examined among which 239 were posi- tive, the total positive rate was 13.8%（239/1 726）. The positive rate in agricultural areas was 11.78% （92/781） and in the pastoral areas was 15.56%（147/945） respectively. The difference between them was significant （~=5.110, P〈0.05）. The positive rates in male and female were 10.17%（76/747） and 16.65% （163/747）. The positive rate was highest in Kazak population, which was 14.83%（213/1 436）, followed by 10.96%（8/73） in Hui nationality. It was the lowest of 6.72% （8/119） in the Han nationality. The serum positive rate in labor population over the age of 30 was at high level. Conclusion Echinococcosis in agricultural and pastoral areas of Urumqi County retained at moderate endemic situation.
