摘　　要：目的探讨神农架林区并殖吸虫病疫源地的分布情况,为预防控制并殖吸虫病提供科学依据。方法应用DIG-FA-kit检测神农架林区人群血清抗体,并与常规ELISA相比较;同时调查中间宿主、动物宿主感染情况。结果共采集人群血清样本1 128份,阳性76份,阳性率为6.74%,ELISA平行对照试验阳性符合率为98.7%。第一中间宿主螺的感染率为0.91%,第二中间宿主淡水蟹感染囊蚴为3.21个/只,动物宿主猫和果子狸的自然感染率为51.72%和15.79%。结论 DIG-FA-kit具有较好的灵敏度和特异性,适合于流行区临床检验和大规模流行病学调查。调查区域有第一、第二中间宿主和保虫宿主的存在,为斯氏狸殖吸虫病自然疫源地。The objective was to survey the epidemic focus of paragonimiasis in Shennongjia and provide the basis for drawing up adequate control strategy.The serum antibody of the people in the area was detected by DIGFA-kit and compared with the result by ELISA.The infection situation of intermediate host and reservoir host in the area was investigated simultaneously.A total of 1 128 serum samples collected from the population,in which 76 were positive with a rate of 6.74%.The masculine coincidence rate was 98.7% by ELISA.The infection rate of snail which considered as the first intermediate host was 0.91%,the infectiosity of limnetic crab which considered as the second intermediate host was 3.21 larvae per crab,and the natural infection rate of cat and civet cat was 51.72% and 15.79%,respectively.The existence of the first and the second intermediate hosts and the reservoir hosts suggests that this area is a natural focus of paragonimiasis skrjabini.
