目的 :摸清库区钩体疫源地的分布、人群钩体抗体水平及菌群分布。方法 :显微凝集试验。结果 :1998年从三峡库区 7个疾病监测点采集健康人血清 513份 ,钩端螺旋体 (钩体 )抗体阳性 165人 (阳性率 32 .16% ) ,各监测点阳性率从 11.11%～ 50 .0 0 %不等。抗体阳性率与性别无关 ,而与年龄密切相关。库区人群含 9群钩体血清抗体 ,以黄疸出血群为主。钩体血清菌群GMT值均不高。结论 :库区人群钩体免疫水平低下 ,应加强钩体病的监测和防治工作
Objective: To find out the distribution of hook flies in the reservoir area, the level of antibody and the distribution of bacteria in the population. Methods: Microscopic agglutination test. Results: In 1998, 513 serum samples from healthy people were collected from 7 disease surveillance sites in the Three Gorges Reservoir area. The positive rate of leptospira antibody was 165 (positive rate was 32.16%). The positive rate of each antibody was 11.11% ~ 50 .0 0%. Antibodies positive rate has nothing to do with gender, but closely related with age. The population of the reservoir area contains 9 groups of hooks serum antibodies, mainly to hemorrhagic jaundice. Gonococcal bacteria GMT value is not high. Conclusion: The immunocompromised leptospira population in the reservoir area is low, so it is necessary to strengthen the monitoring and control of leptospirosis
