Abstract: 【Abstract】 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.
