广州管圆线虫中间宿主螺类调查研究进展

Progress in the investigation of Angiostrongylus cantonensis intermediate host snails

本文回顾了广州管圆线虫中间宿主螺类及其感染情况的相关调查研究,全球共记述49科199种,其中淡水螺类11科87种,陆生螺类共38科112种。我国报道10科33种,其中淡水螺类2科11种,陆生螺类8科22种。尽管近年来我国广州管圆线虫病病例报告数在逐渐下降,但随着福寿螺的不断扩散,自然疫源地不断发现,广州管圆线虫病传播风险持续存在,加强相关中间宿主螺类调查对流行病学研究仍具有重要意义。

This paper reviewed the related investigations on the intermediate host snails of Angiostrongylus cantonensis,and recorded a total of 199 species in 49 families, including 11 families and 87 species of freshwater snails, and a total of112 species of 38 families of terrestrial snails. In China, 33 species of 10 families have been reported, including 2 families and 11 species of freshwater snails, and 22 species under 8 families of terrestrial snails. Although the reported cases of angiostrongyliasis have been gradually decreasing in recent years in China, with the continuous spread of Pomacea spp., more natural foci of A. cantonensis have been found, and the risk of transmission of the disease continues to exist.The findings suggest that strengthening the investigation of related intermediate host snails is significant to understanding of epidemiology of Angiostrongylus cantonensis.
