目的：查明我市福寿螺广州管圆线虫感染情况,有效地预防控制广州管圆线虫病的暴发流行。方法采用肺检法检测2010~2014年福寿螺广州管圆线虫芋期幼虫,分析螺类感染广州管圆线虫情况。结果2010~2014年共检测福寿螺12546只,广州管圆线虫阳性数1521只,阳性率12.1%；5年间采集的福寿螺感染广州管圆线随季节变化而变化,以4月份最高,8月份最低,差异有统计学意义(P<0.05)；市场来源的福寿螺广州管圆线虫检出率较餐饮店来源的检出率高,差异有统计学意义(P<0.05)。结论我市广州管圆线虫的中间宿主福寿螺可检出广州管圆线虫,餐饮店与市场的福寿螺广州管圆线虫检出率差别,可能跟餐饮店与市场对福寿螺的处理不同有关,广州管圆线虫对温度敏感,通过煮熟煮透可大大地杀灭。%Objective To find out the infection status of Ampullaria gigas by Angiostrongylus cantonensis in our city and effectively prevent and control Angiostrongylus cantonensis’s outbreak and prevalence. Methods Larvae of Am-pullaria gigas-Angiostrongylus cantonensis at stage Ⅲ from 2010 to 2014 were detected by lung-microscopy.The infec-tion status of Ampullaria gigas by Angiostrongylus cantonensis were analyzed. Results From 2010 to 2014, 12546 Am-pullaria gigas were tested in total,and 1521 ones were infected by angiostrongylus cantonensis, and positive rate was 12.1%.These collected ampullaria gigas infected by angiostrongylus cantonensis were changed following seasonal varia-tion in the 5 years,April was highest and August lowest.with the significant difference (P<0.05).Detection rate of A m-pullaria gigas-Angiostrongylus cantonensis from market was higher than that from restaurant, with the significance (P<0.05). Conclusion Ampullaria gigas as an intermediate host of Angiostrongylus cantonensis can be detected out of An-giostrongylus cantonensis.There is difference in detection rate of Ampullaria gigas-Angiostrongylus cantonensis from market and restaurant,which maybe related with different disposal methods in restaurant and market.A ngiostrongylus cantonensis is sensitive to temperature, and can be mostly killed by cooking thoroughly.
