쇠우렁에 奇生하는 有尾幼蟲의 種類와 感染調査 : 漢江下流 一部 地域을 中心으로 = "Study on the Infection Rate and the Sorts of Cercaria, Parasitc to Parafossarulus manchouricus"

다국어 초록 (Multilingual Abstract)

There have been no proper investigation made about what kind of parasites are found and in what way cercarias are produced and separated as the season changes, and as so the rate of infection of Clonorchis sinesis in the district "Sootaekri", "Naegokri", "Haengjunaeri" adjacent to the Han River. The aim of this experiment is to examine c10sly the relation between the 2nd intermediate host and the infection by parasites so to make it a basis for the epidemilogical studies of Clonorchis sinensis The results obtained from the investigation are as follows.
1. The natural outflow of cercaria is the greatest in August among Jun., July and August.
2. The rate of infection by cercaria of Clonorchis sinensis to parafessarulus manchouicus is 7.3% at Naegokri, 3.2% at Sootaekri, 3.1% at Haegjunaeri.
3. The total rate of infection by different kinds of cercaria is 17.1% at Naegokri, 10% at Sootaekri, 13.1% at Haegjunaeri.
4. It is confirmed that the parasitic cerearia living on snails are pleurolophocercus cercaria (cercaria of Clonorchis sinensis). Echinostomecercaria, Furcocercus cercaria, and cyathocotyle cercaria.
