摘要/Abstract

摘要： 目的 :调查福建棘隙吸虫等多种吸虫混合感染情况。方法 :采用改良加藤法或水洗过筛沉淀法粪检 ,对吸虫卵阳性人群和终宿主动物分别作驱虫与解剖观察 ,对鱼类宿主取鱼鳃和鱼肉等组织 ,镜检囊蚴。结果 :查出福建棘隙吸虫 ( Echinochasmus fujianensis)、华支睾吸虫 ( Clonorchissinensis)、日本棘隙吸虫 ( Echinochasmus japonicus)、钩棘单睾吸虫 ( H ap lorchis pumilio)和台湾棘带吸虫 ( Centrocestus taiwanense)等 5种 ;人群感染率为 4 .6% ( 81/ 1774 ) ,有 33.7%感染者同时感染 2种或 3种吸虫 ,第二中间宿主为麦穗鱼等 11种 ,感染率为 4 9.1% ( 169/ 34 4 ) ;不同吸虫囊蚴寄生鱼体部位不同 ;保虫宿主为狗、猫和 2种鼠类等 4种 ;混合感染率为 53.5% ( 2 3/ 4 3)。结论 :当地为兽主人次的鱼源性 5种吸虫混合感染区 ,人体自然感染钩棘单睾吸虫系首次报告。

Abstract: AIM:To seek the possible existence of mixed infections of Echinochasmus fujianensis and other fish- borne trematodes.METHODS:Kato- Katz s method and sedimentation proce- dures were used to observe parasite ova in stool.Adult worms were expelled from infected persons after medication and obtained from definitive animal hosts upon dissection.Metacer- cariae of trematodes were detected from gills,muscles and some other tissues of fish after pressing them between two slides and examined under microscopy.RESULTS: Five species of trematodes were found, including Echinochasmus fujianensis, Clonorchis sinensis E. japonicus, Haplorchis pumilio and Centrocestus taiwanense. The overall infection rate in the population was 4. 6% (81/1 774). 33.7% of the the infected persons were contracted with 2 or 3 species of the trematoes. Eleven species of fishes comprising Pseudorasbora parva were identified as the second in termediate hosts, with an average positive rate of 49.1% (169/344). Metacercariae of different species were found to parasitize different parts of fishbody. Dog, cat, Rattus norvegicus and Rattus losea were detected to be the reservoir hosts, the total infection rate being 53.5% (23/43). CONCLUSION: There are 5 major species of fish-borne trematodes which may cause mixed infections in the study regions. Actually, infections of these trematodes in situ are more prominent in animals. This is the first report on human infection of Haplorchis pumilio in our country.
