摘　　要：目的了解韶关市武江区华支睾吸虫感染状况,为制定防治方案提供依据。方法采集1岁以上的常住人群粪便为标本,用清水沉淀集卵法对感染者进行虫卵计数;常见螺蛳分类后压碎于解剖镜下找尾蚴;捕捉淡水鱼分类后取鱼肉压片找囊蚴;清水沉淀集卵法查找家畜粪便虫卵,解剖野鼠肝胆寻找成虫。结果6个点人群粪检3397例,感染者292例,感染率为8.6%。其中轻度感染276例,占94.5%;中度感染14例,占4.79%;重度感染2例,占0.68%。解剖纹绍螺11083只,感染32只,感染率为0.29%;长角涵螺440只,感染4只,感染率为0.91%。解剖淡水鱼334尾,272尾感染,感染率为81.43%。家畜猫粪检33份,感染17份,感染率为51.52%;猪粪58份和牛粪27份,未发现虫卵。解剖猫6只,均找见成虫,猪58头及野鼠43只未发现成虫。结论韶关市武江区存在华支睾吸虫感染,经多年大力防治取得了成绩,人群感染轻度占多数,但仍需继续开展防治工作。Objective To access the distribution and extent of Clonorchis sinensis infection in Wujiang District, Shaoguan city and to provide basis for the development of disease prevention program. Method Stool samples from the residents of age over 1-year-old were collected. Clonorchis sinensis eggs were collected by water sedimentation. After identification, BeUamya purificata were crushed and the cercariae were identified under a microscope. Freshwater fish was also identified and the metacercariae were collected by fish-extrusion method. Clonorchis sinensis eggs in animal feces were collected by water sedimentation method. Adult Clonorchis sinensis in wild rats＇ liver were studied by microscopic examination. Result A total of 3397 stool samples were analyzed.292 subjects were found infected and the infection rate was 8.6%. The percentage of mild, moderate and severe infection was 94.5 （276 cases）, 4.79 （14 cases） and 0.68% （2 cases）, respectively. Among the 11083 examined snails （Parafossarullaus striatulus）, 32 snails （0.29%） had infection. 4 out of 440 Alocinma longicornis snails （0.91%） had infection. For the freshwater fishes, 272 out of 334 had infection （81.43%）. For the animal feces, 17 out of the 33 fecal samples （51.52%） from cats had parasite eggs. No egg was found in the fecal samples from pigs （58 samples） and cows （27 samples）. Adult worms were found in cats （6） but not in pigs （58） and wild rats （43）. Conclusion Clonorchis sinensis infection is common in Wujiang District, Shaoguan city. Most of the infections in human are mild. Preventive measures should be taken for the control of Clonorchis sinensis infection.
