摘要:   目的 探讨江西省卫氏并殖吸虫病流行状况及其变化的原因。 方法 选择江西省靖安县、万载县2个林场和玉山县1个镇进行流行病学调查和回顾性分析,调查卫氏并殖吸虫病中间宿主放逸短沟蜷 (Semisulcospiralibertina)与华溪蟹 (Sinopotamonspp.)、保虫宿主 (猫、犬、果子狸、野猫等)感染率,以及流行区生态环境变化和人群个体行为变化。 结果 卫氏并殖吸虫病流行区中间宿主放逸短沟蜷与华溪蟹平均感染率分别为0.21%和54.3%,保虫宿主平均感染率为56%。与20年前比较,华溪蟹感染率明显下降。 结论 江西省原流行区仍有卫氏并殖吸虫病流行 ,生态环境改变可能导致华溪蟹的感染率下降。

Abstract:  Objective To investigate Paragonimus westermani infection in the intermediate hosts and animal reservoivs in Jiangxi Province. Methods Two forest farms in Jingan and Wanzai Counties and one town in Yushan County of Jiangxi Province were selected as pilots for epidemiological and retrospective survey. The intermediate hosts (snails, crabs) and reservoir hosts(cat, dog, civet cat, wildcat, etc.) were collected and examined. Data on the changes of ecological environment and people's behaviors were also collected. Results The average infection rate in Semisulcospira libertina and Sinopotamon spp. was 0.21% and 54.3% respectively, and that of reservoir hosts was 56%. Compared with those in 20 years ago, the infection rate in Sinopotamon spp. decreased considerably. Conclusion The three areas are still endemic for P.westermani with lower prevalence than before possibly due to the change of ecological environment.
