摘要
对辽宁省凤城县四条河流9个自然村进行了卫氏并殖吸虫类型调查。观察了囊蚴、成虫、虫卵形态及成虫染色体核型。证实该县存在卫氏并殖吸虫两型。位于靉河上游金家河伙荣沟村的卫氏并殖吸虫为三倍体型,该村有现患,人群皮试阳性率为26.7%;而靉河下游秋岭村的卫氏并殖吸虫为二倍体型,无典型病人发现,人群皮试阳性率为2.1%。两型形态除囊蚴大小不同外,以虫卵的区别最为明显。同时就两型卫氏并殖吸虫对人体的致病性及鉴别进行了探讨。
A survey on the type of Paragonimus westermani was performed at the 9 villagesalong side the 4 rivers in Fengcheng county,Liaoning province. Morphological fea-tures of the metacercariae, as well as their adult eggs and karyotypes were studied. The results proved that the two types of P.westermani coexisted in this area.P .wes -termani in Huo Yingou village which located at the upper reaches of Ai river wastriploid type and typical patients with lung symptoms were found.Positive rate ofintradermal test in the inhabitants was 26.7 % ; while the P. westermani in QiuLing village at the lowerreaches of Ai river was diploid type and no typical patientswas found.Positive rate of intradermal test in the inhabitants was 2. 1 % .Remar-kable morphological distinction was observed between the eggs of the two typesbesides the size of metacercariae. Pathogenicity of the two types to the humanbody is discussed.
