目的掌握兴山县钩端螺旋体病(钩体病)宿主动物带菌及人群免疫水平,为进一步做好钩体病的预防与控制提供依据。方法按照《全国钩端螺旋体病监测方案》开展鼠、家畜、青蛙等宿主动物带菌调查及健康人群血清学监测。结果平均鼠密度为1.80%。鼠种构成以黄胸鼠、小家鼠和黑线姬鼠为优势种,平均带菌率为3.75%。共检测病人尿液及家畜、青蛙、稻田疫水等7类样本565份,培养阳性菌株4株,阳性率为0.71%,其中稻田疫水2株,病人尿液、蛙肾各1株,菌株经鉴定黄疸出血群1株,秋季热群3株。人群钩体抗体阳性率平均为28.62%,青壮年阳性率较高,以黄疸出血型、七日热型、流感伤寒型、波摩那型为主。在监测中发现1例在农贸市场感染的经济型钩体病。结论兴山县钩体宿主动物带菌率低,血清学显示人群钩体隐性感染率较低,在山区型钩体自然疫源地存在的情况下,其发病率与社会因素和自然因素密切相关。农贸市场、畜牧养殖区及其周边为经济型钩体病疫源地,病例分析已经得到证实,建议今后应将其纳入预防和监测范围。
Objective To understand the host bacteriostasis of Leptospirosis (leptospirosis) in Xingshan County and the level of population immunity in order to provide basis for further prevention and control of leptospirosis. Methods According to the “National Leptospirosis Surveillance Program” to carry out host strains of mice, domestic animals, frogs and other serological surveillance of healthy people. Results The average rat density was 1.80%. The rodents were dominated by Rattus flavipectus, Mus musculus and Apodemus agrarius with the average rate of 3.75%. A total of 565 samples were collected from 7 samples of urine and domestic animals, frogs and paddy fields, and 4 strains were positive. The positive rate was 0.71%, of which 2 were from paddy field and 1 from the urine and frog kidney. Identified jaundice bleeding group 1, autumn heat group 3. The average positive rate of the population hook body antibody was 28.62%, the positive rate of young adults was high, with jaundice hemorrhagic, seven-day fever type, influenza type, Pomona type. During the monitoring, 1 case of leptospirosis was found in the farmer’s market. Conclusion The host bacteria in Xueshan County is low, and the serology shows that the prevalence of latent infection in the population is relatively low. In the presence of natural foci in mountainous area, the incidence rate is closely related to social and natural factors . Farmers’ markets, livestock breeding areas and their surroundings are the source of economic leptospirosis. The case analysis has been confirmed. It is suggested that they should be included in the scope of prevention and monitoring in the future.
