曲旋沼螺作为华支睾吸虫第一中间宿主的新发现

Three species of fresh water snails,Parafossarulus striatulus, Bithynia Kiusiuensis and a new species were obtained in a pond near the He-sheng production brigade, Hailong county, Jilin. This county has been known as an epidemiological district of C. sinensis. Cercarie of C. sinensis were found not only in Parafossarulus striatulus but also in the new species. Infection rate of cercarie was 0.3% and 3.0%, respectively. The new species is long ovate-shaped. The height of spiral shell is 15.2-16.9mm, and the width 7.7-8.3mm.
This new species has been identified by Comrade Liu Yue-ying of the Institute of Zoology, Academia Sinica, and given the name Parafcssarulus anomalo spiralis. As an intermediate host of Clonorchis sinensis it was discovered for the first time.
