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。
Objective: To investigate the mixed infections of many kinds of flukes in Fujian Province. Methods: The modified Kato method or washing screened sedimentation method was used to test the deworming and dissecting of the positive population and the final host of the trematode. The fish host picked gill, fish and other tissues and examined the metacercariae. Results: Echinochasmus fujianensis, Clonorchissinensis, Echinochasmus japonicus, Hpa lorchis pumilio and Centrocestus taiwanense were isolated from Fujian Province. (81/1774), 33.7% were infected with 2 or 3 flukes at the same time, the second intermediate host was 11 species of wheat, the infection rate was 41.1% (169/34 4); different parasitized fish metacercaria parasitic fish body parts; host for the protection of dogs, cats and two kinds of mice and other 4 kinds; mixed infection rate was 53.5% (23/43). CONCLUSIONS: There are 5 fish-endemic mixed-infection areas in the area, and the human body is naturally infected with the clonorchis histolytica.
