摘　　要：目的调查云霄县淡水蟹种类及其感染并殖吸虫囊蚴的情况。方法选取不同地理方位为调查点,捕捉各调查点的淡水溪蟹进行分类和并殖吸虫囊蚴的检查。结果全县共调查6个乡(镇)20个村,共捕捉230只蟹,查出漳州华溪蟹(n=136)、漳浦束腰蟹(n=63)和闽溪蟹(待定种)(n=31)3种;检出感染并殖吸虫蟹15只,阳性检出率为6.6%(15/230),蟹的感染指数为0.11,对福建华溪蟹和中华束腰蟹种类及分布作了修正。结论云霄县并殖吸虫宿主淡水溪蟹有3种,蟹感染并殖吸虫呈下降趋势,但仍为中度并殖吸虫疫源地。Objective To study the distribution of freshwater crabs and their infection by Paragonimus in Yunxiao county, Fujian. Methods Freshwater crabs were collected and identified. The crabs were then dissected and examined for the presence of Paragonimus metacercariae. Results Six tons of crabs from 20 villages （Yunxiao county） were collected. Three species of crabs were found, namely Sinopotamon zhangzhouense, Somanniathelphusa zhangpuensis and Minpotamon spp. The infection rate was 6.6% （15/230） for the Paragonimus, and the index of crab infection was 0.11.
