【摘要】 1984年7月在嵊县毫石乡毫岭村和石道地村进行肺吸虫病调查,用肺吸虫成虫抗原作皮内试验,共检查316人;其中毫岭村166人,皮试阳性者17人,阳性率为10.24％;石道地村150人,阳性者32人,阳性率为21.33％,经统计学处理,皮试阳性率,石道地村明显高于毫岭村(x~2=7.4 p<0.01)。从毫岭村捕捉肺吸虫第二中间宿主——浙家华溪蟹211只进行检查,肺吸虫囊蚴感染率为35.5％,感染度平均为1.93个/只。从该乡捕捉肺吸虫第一中间宿主——放逸短沟蜷1685只进行检查未发现肺吸虫幼虫期。在当地捕获的13只沟鼠,经解剖观察未发现肺吸虫寄生,由于调查数量和种类少,该地区是否有肺吸虫保虫宿主存在,尚需进一步深入调查。更多还原

【Abstract】 An epidemiological survey was done on Paragonimiasis in a mountain village of Sheng County, Zhejiang Province, in July, 1984.Adult antigens of Paragonimus was used in the survey and 316 cases were examined. It was found that the antigen skin test was positive in 10.24% in the Hao Ling village and 21.33% in the Shi Dao De village respectively. The latter was significantly higher. Skin test comparison between age-groups from 5 to 20,21 to 50 and ≥50 years, showed no statistical differences. The positive rates of skin test was 19.61% in male and 11.66% in female, there is no signif cant difference Statistically. The second intermediate host of Paragonimus is Sinopotamon chekiangense in Hao Ling village. 211 crabs were examined and an infection rale of 35.5%, was found. Metacercaria varied between 1 to 20 per infected crab, averaging 1 .93/metacercariae per crab. 93 fresh metacercariae conformed to Paragonimus westermani. When measured, they averaged 349×356 μm. 1685 snails (Semisulcospira libertina) were examined, no larvae of Paragonimus were found. 13 rats (Eattus norvegicus) were dissected and no adult Paragonimus was found, however, the number of animals examined was too few to draw conclusions.更多还原
