摘要： 目的  了解绵阳市江油市包虫病的流行现状，为制定防控策略提供依据。 方法  对江油市2005~2015 年报告的包虫病病例进行调查；对当地感染病例所在乡及毗邻乡镇的人群进行B超筛查，阳性者做血清学检测。对终宿主和中间宿主动物进行调查，检测犬粪包虫抗原，捕获野鼠进行解剖。 结果  共调查包虫病病例8 例，其中3例为当地感染病例；共对3 028人进行B超筛查，发现肝囊肿、包块、钙化点等异常人群91人。采集B超异常人群的血液标本87份，进行包虫病IgG 抗体酶标检查，阳性率9.20%。检测犬粪503份、猫粪49份，无阳性发现。捕获鼠类91只，无阳性发现。 结论  江油市出现了本地感染包虫病病人，本次调查未发现新病人，也未找到病原体，但包虫病传播链存在, 下一步要继续做好流行病学研究，同时加强防控工作。

Abstract:

Objective  To investigate the prevalence status of echinococcosis in Jiangyou area in Mianyang city for scientific evidences to plan control and preventive measures for this disease. Methods  Investigation was performed in the reported cases in Jiangyou county from 2005 through 2015, and ultrasound screening was carried out for the local infected subjects and population living neighborhood areas. The positive cases received further serological studies. In addition, the definitive and intermediate hosts were investigated, including detection of the hydatid cysts in the feces of dogs and dissection of the wild rodents captured. Results  A total of 8 cases of echinococcosis were investigated, in which 3 were local infections. Abnormal condition associated with liver cyst, abdominal mass and calcifications was identified in 91 of 3028 cases. Eighty-seven blood samples were obtained from subjects with abnormal ultrasound findings, and subjected to echinococcus IgG detection, which revealed positive rate of 9.20%. Detection in 503 portions of feces from dogs and 49 portions from cats showed no positive results. Ninety-one rodents were captured and dissected, and no positive infection was found. Conclusion  Local infection of echinococcosis was found in Jiangyou county. Although no new infection was reported, and pathogens were not detected, yet the transmission chain of echinococcosis must exist, suggesting that following epidemiological studies and strengthened prevention and control measures remain necessary.
