摘　　要：目的探讨漳州市辖区漳浦等4县广州管圆线虫中间宿主感染情况。方法在漳浦等4县8个调查点采集中间宿主,用肺检法、匀浆法检查其体内广州管圆线虫幼虫。结果共调查12种贝类1 844份样本,有11种检出广州管圆线虫Ⅲ期幼虫,感染率12.6%（217/1 723）;感染率前3位是高突足襞蛞蝓38.9%（61/157）、褐云玛瑙螺28.3%（86/304）和福寿螺19.7%（34/173）,其他种类感染率1.2%~6.8%;不同种类宿主感染率差异较大;4县感染率较接近,漳浦12.9%（58/451）、诏安14.0%（58/415）、平和11.6%（52/448）、长泰12.0%（49/409）;靠近居民住宅点的感染率为20.2%（171/845）,村外调查点为5.2%（46/878）,村外点感染率较低。结论广州管圆线虫对中间宿主的选择性不强,中间宿主种类多,但不同孳生环境和不同宿主感染率有明显差异。Objective To investigate the infection rates of Angiostrongylus cantonensis in Zhangpu and other four counties.Methods In eight spots of four counties,the larvaes of intermediate host were investigated by checking lung and homogenate method.Results Totally 12 kinds of Angiostrongylus cantonensis in 1 844 samples of 11 kinds of hosts were detected out and infection rates was 12.6%（217/1 723）.The higher rates of the host were as follows：Vaginulus alte（38.9%,61/157）,Achatina Fulica（28.3%,86/304）and Pomacea canaliculata（19.7%,34/173）,respectively.The infection rates of other kinds of hosts were from 1.2% to 6.8%.There was significant different rates for the species of hosts.The infection rates in Zhangpu（12.9%,58/451）,Pinghe（14.2%,59/415）,Zhaoan（11.6%,52/448）and Changtai（12.0%,49/409）were similar.The infection rate of the spots close to resident houses was 20.2%（171/845）,the rate out of villages was 5.2%（46/878）,and the rate out of villages was lower than that in the villages.Conclusion There are various hosts and different types of breeding ground involved in the transmission of Angiostrongylus cantonensis and the infection rates are significantly different for different hosts.
