浙江省台州市福寿螺分布和广州管圆线虫感染调查

Distribution of Amlullarius gigas and its infection status with <I>Angiostrongylus cantonensis</I> in Taizhou city

摘要

摘要: 目的　探讨浙江省台州市福寿螺分布及广州管圆线虫感染状况。方法　在全市9个县（市、区）所有乡镇开展福寿螺分布调查，抽取5个县（市、区）开展福寿螺广州管圆线虫感染状况调查。结果　全市58.78％（77/131）的乡镇有福寿螺分布，呈自南向北逐渐递减分布（sup2/sup=38.15, IP/I＜0.01）；福寿螺广州管圆线虫感染率为3.35％（25/747），感染率沿海地区高于内陆地区（sup2/sup=6.60,IP/I＜0.01）。结论　台州市福寿螺分布广泛，广州管圆线虫感染率较低，但存在发生广州管圆线虫病的潜在威胁。

Abstract: Objective　To investigate the distribution of IAmpullarius gigas/I (apple snail) and its infection status with pAngiostrongylus cantonensis/I in Taizhou. Methods　Investigation of the distribution of IAmpullarius gigas/I was conducted in all villages of 9 counties (cities/districts) in the city, and the investigation of the infection status of IAmpullarius gigas/I with IAngiostrongylus cantonensis/I was conducted in 5 counties randomly selected. Results　IAmpullarius gigas/I distributed in 77 townships (58.89%) with the density decreasing as going north（sup2/sup=38.15, IP/I＜0.01）; the infection rate with Angiostrongylus cantonensis was 3.35％（25/747）, which was higher in coastal area than inland area（sup2/sup=6.60, IP/I＜0.01). Conclusion　The distribution of IAmpullarius gigas/I was wide in Taizhou, but with low infection rate with IAngiostrongylus cantonesis/I, however, the potential of the incidence of angiostrongyliasis cantonensis still exists.
