Abstract: 【Objective】In order to provide guidance for prevention and cure of Schistosomiasis, controlling techniques were studied according to the features of mountainous epidemic districts. 【Method】The epidemiology and controlling techniques of Schistosomiasis japonica of mountainy livestock in Sichuan Province were studied. Epidemiology position and functions of every kind of domestic animal were revealed, and controlling techniques were researched. 【Result】The schistosomiasis bovine were the main source of the infection. IPC(Index of Potential Contamination) of the bovine at the age of 3 to 8 years old was much higher than others. Feces on the pasture, the majority of which was excreted by bovine, were very important transmission factors. Epidemic situations of schistosomiasis among human being and animals had a marked and positive correlation (r﹥r0.01, P﹤0.01). The epidemic mountainous district was divided into two types that were semi-closing epidemic district(s-CED) and closing epidemic district(CED). The former was mainly human being, Lushan county as representative. The latter was mainly domestic animals, Puge county as representative. Epidemiology position and function of buffalo was more important than cattle in s-CED, but cattle was more important than buffalo in CED. 【Conclusion】Bovine were mainly treated in s-CED, and all domestic animals were must treated in CED. The time of treatment in the late-autumn and early winter was much better than in summer that was traditional.
