[Longitudinal observation of epidemic dynamics of schistosomiasis in bovine in two mountainous endemic regions].

Objective: To understand the endemic situation dynamics of schistosomiasis in domestic animals (mainly bovine) in mountainous endemic regions, so as to provide the reference for evaluating the control effect and improving control strategy.

Methods: Two representative pilots (Renmei and Dacang) in mountainous schistosomiasis endemic regions were selected for survey. The schistosome infection status of bovine was investigated by the miracidium hatching method, the pasture of bovine were investigated by home visiting, and the distributions of wild feces and Oncomelania snails, and the snail schistosome infection status were also investigated in April and September every year.
