目的了解广东肇庆市褐云玛瑙螺和福寿螺广州管圆线虫的感染情况。方法用消化法对采集的螺进行处理,镜下检查和计数幼虫,然后用获得的幼虫感染小鼠。结果褐云玛瑙螺广州管圆线虫第3期幼虫的感染率约为12.55%,平均感染度为15.66;福寿螺的感染率约为10.79%,平均感染度为41.65。从感染小鼠脑部检获广州管圆线虫虫体,小鼠血清特异性IgM均呈强阳性。结论肇庆褐云玛瑙螺和福寿螺均存在广州管圆线虫感染。且2种螺在当地广州管圆线虫传播中均有重要作用。
Objective To understand the infection of Aralia elata and Acanthostrobus in Zhaoqing, Guangdong Province. Methods Processed spirochetes were treated by digestion, larvae were examined and counted microscopically, and mice were then infected with the obtained larvae. Results The infection rate of 3rd instar larvae of A. anglica was about 12.55% and the average infection rate was 15.66. The infection rate of B. tabaci was about 10.79% and the average infection rate was 41.65. Serum-specific IgM was strongly positive in seizures of A. litura from infected mice. Conclusions Both Agropyron noctua and Snails beetle in Zhaoqing were infected by C. elegans. And two kinds of snails in the local Guangzhou pipe worm have an important role in transmission.
