【摘要】 1965年对2个生产队共1,365人进行有关本病调查。肝吸虫皮试阳性率和大便肝吸虫卵阳性率分别为33.7%和12.4%。同地区2～16岁年龄组的感染率明显高于16岁以上者。检查纹沼螺267只,一只(0.38%)查见肝吸虫尾幼。检查6种鱼,麦穗鱼和虎头鱼的肝吸虫囊幼感染率分别为80.7%和37.3%。每克麦穗鱼带囊173～962个。查6只猫,3只便有肝吸虫卵。在当地赤脚医生协助下,边查、边治、边做预防卫生宣传。已查出虫卵的146例,就地用六氯对二甲苯进行治疗,近期疗愈率为88.1%。1972年应用同样方法对当地进行复查,皮试和肝吸虫卵阳性率已分别降低至15.0%和3.8%。更多还原

【Abstract】 In 1965, a survey on clonorchis was carried out among 1,365 persons in 2 production brigates of the Shuangchiao Commune near Beijing. Intradermal test and stool examination were used for the survey and the positive rate for clonorchiasls of the 2 tests was 33.7% end 12.4% respectively. The infection rate for the 2～16 age group was found to be significantly higher than that of the group over 16. Of 267 fresh-water snails (Parafossarulus striatulus) examined, One snail (0.38%) was found to harbour clonorchis cercariae. 6 species of fresh-water fishes were captured and examined for clonorchis metacercaria and the positive rate in Pseudorasbora parrs and Abbottina rivuiaris was found to be 80.7% and 37.3% respectively. Each gram of flesh of the former might contain 173～962 metacercariae. Of 6 domestic cats examined. 3 were positive for clonorchis ova. In cooperation with barefoot dorctors, health campaign was conducted and proper treatments were given to those found to be infected. Of these, 146 were treated at home with hexachloroparaxylol. The immediate cure rate obtained was 88.1%. In 1972, a resurvey was made in the same area with the same methods. The positive rate obtained by intradermal test and stool examination was 15.0% and 3.8% respectively, indicating that the infection rate was declining更多还原
