摘要
目的了解广东廉江褐云玛瑙螺和福寿螺感染广州管圆线虫的情况。方法使用消化法对从上述地点采集的褐云玛瑙螺和福寿螺进行检查,并用检获的幼虫感染大鼠。结果共检查褐云玛瑙螺388只,福寿螺296只,广州管圆线虫第3期幼虫的阳性率分别为24.0%和8.1%;感染度分别为1~218和1~8。从上述感染的实验大鼠中均检获到广州管圆线虫成虫。结论广东廉江地区福寿螺存在广州管圆线虫感染,但目前褐云玛瑙螺可能在当地广州管圆线虫传播中仍起主要作用。
To learn more about the natural infection rate of Angiostrongylus eantonensis in Aehatina fulica and Ampullaria gigas from countryside of Lianjiang District of Guangdong Province, Methods With the digestion method, the achatina fulica and ampullaria gigas were transacted from the district, then infective larvae from the snails were used to infect rats. Results 388 of achatina fulica and 296 of ampullaria gigas were examined. Their infective rate of angiostrongylus eantonensis were 24.0 % and 8.1%, their infectiosity being 1~218 and 1~8 respectively. Adults of angiostrongylus eantonensis were seen in all infected rats. Conclusions There are infection of angiostrongylus eantonensis in ampullaria gigas from countryside of Lianjiang District of Guangdong Province, but achatina fulica may play a major role in transmission of the parasite in the place now.
