一起聚集性腱鞘囊肿病例发病的病因学研究与事件控制

Etiological Study and control of an aggregative ganglion case

目的揭示该起聚集性腱鞘囊肿病例发病的病因,采取针对性措施控制事件发展。方法调查病例发生地的羊及人的发病情况,用SAT实验检测抗布鲁杆菌抗体,血液、腱鞘囊肿液进行布鲁杆菌分离培养。羊进行整群淘汰、环境进行终末消毒、对查出的病人和感染者进行治疗。结果 2011年春节前后该屯羊发生集中流产,抽检40只羊查出布病羊15只。查出有前述接触史、症状体征者共42人,SAT检测结果为7例囊肿病例、2例发烧病人和2例无症状的村民共11例阳性;囊肿穿刺液的病原分离结果阴性,从1名发烧病人的血液分离到羊种Ⅲ型布鲁杆菌。经过治疗7例囊肿病例囊肿消退、2例发烧病人康复,随访1年该屯无新病例发生。结论 7例腱鞘囊肿病例为布鲁杆菌病,感染布鲁杆菌是布病流行区腱鞘囊肿的病因之一。

Objectives To reveal the cause of aggregative ganglion cases and measures of ganglion control. Methods We investigated the morbidity situation of sheep and human in cases occurred area. We detected the brucella antibody in human and sheep with SAT test. At the same time, we separated the brucella from the samples of blood and ganglion fluid of the cases. All the sheep were eliminated, the situation was terminally disinfected, the infected patients found out were treated with anti-brucellosis methods. Results Collective abortion was found before and after the Spring Festival in 2011. From all the samples of 40 sheep, 15 were detected as brucellosis cases. We found out 42 persons with the contact history, symptoms and signs. SAT test showed that 7 ganglion cases, 2 fever cases and 2 farmers without symptom, a total of 11 cases of positive. The result of the separation etiology of ganglion fluid was negative. We isolated the sheep type III brucella from a fever case blood. After the treatment, 7 cases had not ganglion any more, and 2 fever cases were rehabilitated. Follow-up of 1 year was conducted, but no new case in the country was found. Conclusion Seven ganglion cases were diagnosed as brucellosis. Brucella infection is one of the causes of ganglion in the brucellosis epidemic area.
