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。
Objective To understand the infection of Helicobacter pylori in Lianjiang, Guangxi, and the snakehead worm in Guangxi. Methods The A. niloticus and A. snails collected from these sites were examined by digestion and infected with seized larvae. Results A total of 388 brown snails and 296 snails were examined. The positive rates of larvae of stage 3 larvae were 24.0% and 8.1%, respectively. The infection rates were 1 ~ 218 and 1 ~ 8, respectively. All the infected adults were harvested from the infected experimental rats. Conclusion There is an infection of A. cantonensis in LianSuoLuo, Lianjiang, Guangdong Province. However, A. niloticus may still play a major role in the transmission of C. elegans in Guangzhou.
