报道四川省名山和峨边县为陶氏颚口线虫典型流行区，猪的感染率为５．６％和１８．６％；在流行区新发现４种蛙和一种蟾蜍为本虫的第二中间宿主．野猪是本病的重要感染源，感染率高达６８．２％．实验证明鼠类和家鸡、鸭为本虫的适宜转续宿主．

This paper reports the epidemiology of Gnathostoma doloresi and thetest of its larvae in animals. The surveys of epidemiology first found that Mingshan and E-bian County,Sichuan Province were a typical endemic area of G. doloresi,where the inci-dence rate of G. doleresi was 5.6% and 18.6% in pig. It the first found that four species offrogs,namely Rana tigrina rugulosa,R. nigromeculata,R. liminocharis,R. phrynoides andone species toad,Bufo bufo gargarizans were infected naturally with the advanced 3rd-stagelarvae of G. doloresi. In Fujian Province,total of 44 wild boars,Sus scrofa were examinedand among 30(68.2%)were found to be infected with G. doloresi and the authors considerthat in china,Frogs and wild boar are an importance infection sources for gnathostomiasisdoloresi.Our test has proved that rodents and Gallus gallus domesticus,Anas platyrhynchusdomesticus can be serve as the paratenic hosts for the parasite.
