青海省治多县棘球蚴病流行病学调查报告

【提要】 2006年7月在青海省治多县对1岁以上人群进行调查，间接红细胞凝集试验（IHA）检测棘球蚴抗体阳性率为4.5%（42/933）、ELISA的阳性率为8.2%（76/931），B超检查（结合血清学检测和临床表现判断）患病率为3.4%（33/979），其中细粒棘球蚴病和多房棘球蚴病患病率分别为3.2%（31/979）和0.2%（2/979）。用剖检法检测高原鼠兔棘球蚴感染率为15.1%（14/93），其中1例病变脏器经分子生物学鉴定确认为石渠棘球蚴病。用ELISA检测粪便棘球绦虫抗原阳性率，犬粪为6.2%（12/193），狼粪为35.7%（5/14）。认为治多县为多种棘球蚴病混合流行区。

An Epidemiological Survey on Echinococcosis in Zhiduo County of Qinghai Province

The survey was carried out in July, 2006 in Zhiduo County. The IHA and ELISA positive rate in human population was 4.5% (42/933) and 8.2% (76/931) respectively. Ultrasonography revealed a morbidity of 3.4% (33/979) with 3.2% Echinococcus granulosus and 0.2% of E.multilocularis respectively. Animal dissection showed an infection rate of 15.1% (14/93) in pikas with one infected by E.shiquicus proved by molecular biology. Coproantigen rate by ELISA was 6.2% (12/193) in dogs and 35.7% (5/14) in wolves. The results indicated that Zhiduo County is a mixed endemic area for echinococcosis.
