杭州市及周边地区广州管圆线虫疫源地调查

Investigation of epidemic foci of <I>Angiostrongylus cantonentsis</I> in Hangzhou and the surrounding areas

  • 摘要: 目的 了解杭州市及周边地区福寿螺分布及螺体内广州管圆线虫感染情况。方法 调查深入杭州市主要农贸市场、餐馆(13所农贸市场、20家餐饮场所),收集杭州市周边地区外环境及螺类养殖场的福寿螺195只,利用肺检法和组织匀浆法进行螺体内广州管圆线虫感染情况的调查。结果杭州市主要农贸市场都曾有过福寿螺出售,部分川菜、粤菜餐馆供应的福寿螺,货源主要来自外省;周边地区有大量福寿螺野外生存,并在绍兴剡溪江捕获的福寿螺广州管圆线虫Ⅲ期幼虫阳性,阳性率为0.75%。结论 浙江省除温州以外的钱塘江以南地区也有阳性福寿螺野外生存,应加强监测和健康教育,预防广州管圆线虫病的发生。

     

    Abstract: Objective The study was conducted to investigate the distribution of apple snails (Ampullariidae) in Hangzhou and the surrounding areas so as to identify IAngiostrongylus cantontensis/I infections in these snails. Methods In-depth field surveys were performed in mainstream farmers markets, restaurants (13 markets and 20 restaurants) to assess the sales of apple snails. A total of 195 apple snails were collected from the environment in the vicinity of Hangzhou city and from snail farms in order to identify IAngiostrongylus cantontensis/I infection using lung and tissue homogenization. Results Sales of apple snails were active in various mainstream markets, and some of the supply to Sichuan and Cantonese restaurants originated from other provinces. A large number of apple snails lived in the surrounding areas of Hangzhou. Phase III larva of Angiostrongylus cantonensis were found in those captured in the Yan River of Shaoxing, the positive rate being 0.75%. Conclusion IAngiostrongylus cantontensis/I infected apple snails were found living in the southern area of China apart from Zhejiang province. Therefore, intensified surveillance, as well as broader health education, was needed for the prevention of angiostrongyliasis.
