目的调查茂名市广州管圆线虫终末宿主鼠类的感染情况。方法在茂名市用鼠夹、鼠笼捕捉鼠类,鉴定鼠种,处死后检查寄生于鼠心、肺血管内的广州管圆线虫成虫。结果共检查鼠类196只,其广州管圆线虫自然感染率为10.71%。其中褐家鼠感染率为11.93%(21/176),小家鼠感染率为0(0/20)。结论茂名市褐家鼠存在一定程度的广州管圆线虫感染,是该虫的重要终末宿主。
Objective To investigate the infection status of Terminal Trichinella spiralis nematodes in Maoming city. Methods In Maoming city, mice were caught by mousetrap and squirrel cage, and the mice were identified. After sacrifice, the adults of C. elegans were checked for parasitism in rat heart and pulmonary vessels. Results A total of 196 mice were examined. The natural infection rate of C. elegans was 10.71%. Including Rattus infection rate was 11.93% (21/176), Mus musculus infection rate was 0 (0/20). Conclusion There is a certain degree of infection of C. elegans in Rattus norvegicus in Maoming and it is an important terminal host of this worm.
