【Abstract】 Objective To study the infection of freshwater fishes with the encysted metacercaria of Clonorchis sinensis. Methods Meat, gills and scales samples were collected from the freshwater fishes, digested by artificial stomach liquid and examined for the encysted metacercaria of Clonorchis sinensis under microscope. Results The average infection rate of Ctenopharyngodon idellus was 0.8 per gram in meat, 0.05 per gram in scale and 0.28 per gram in gill. The infection rate of Parabramis pkinesis was 0.33 per gram in meat. The encyted metacercaria was not found in Laveo kontius. Conclusion Encysted metacercaria of Clonorchis sinensis were found in freshwater fishes in Nanzhuang, Jiujiang and Longjiang of Fushan, and Zengcheng and Conghua of Guangzhou. The infected freshwater fishes could be the source of parasitic zoonoses infection of these areas.更多还原
