Abstract


Studies were made of the infection of Clonorchis sinensis in human subjects and river fishes living in-the area of Kwangju, Naju, Whasoon, Changsung and Koksung, Chonnam province. The infection of flukes was determined by stool examination of the inhabitants and by the infectivity of the metacercaria in river fishes obtained from the area, the results of which are presented below.
1. It is confirmed that Naju is a prevalent area of Clonorchis sinensis and Koksung is of Metagonimus yokogawai.
2. Deep water fishes showed a lower infectivity toward metacercaria, while shallow-water fishes exhibited a high incidence of the infection. The incidence of Pseudoperilampus morn ranked highest in rate with 92.5%, followed by, Plecoglossus altivelis 85.0%, Zacco platypus 82.0%, Gnathopogon majimae 78.0%, Carassius carassius 72.0%, Cyprinus carpio 35.0% and Channa argus 8.3% in order. It is noteworthy that any metacercarcaria infection was not detected in Parastlurus Asotus and Misgurnus anguillicaudatus.
3. Histological examination of fish integument revealed that those fishes with high infectivity have thin and loose cuticle and lower infective fishes thick cuticle.
