目的了解广州管圆线虫在广西边远山区的螺类及鼠类自然感染状况,为当地的防治提供科学依据。方法采集天峨县境内不同地理位置及不同孳生环境的活体福寿螺、石螺、蚌和诱捕野外鼠,采用酶消化法逐个检查各类软体动物感染阳性率及幼虫数,并解剖检查野外鼠了解广州管圆线虫感染情况。结果交通方便山区福寿螺的感染率为18.15%,石螺为5.0%,而交通不便的山区乡螺类未发现感染,但鼠类在交通方便、离县城近的乡镇或交通不便的边远山区乡均发现感染阳性鼠。所调查的蚌类未发现感染。结论该县存在广州管园线虫自然疫源地且感染率高,感染度重。同时发现石螺也是广州管圆线虫感染的中间宿主。对当地人群容易造成感染,应引起高度关注并加强宣传教育。
Objective To understand the natural infection of snails and rodents in the remote mountainous areas of Guangxi, and to provide a scientific basis for local prevention and treatment. Methods Live snails, snails, mussels and trap wild animals were collected from different geographical locations and breeding environments in Tian’e County. The positive rate and number of larvae of mollusks were examined by enzymatic digestion method one by one. Pipeline infection. Results The accessibility rate was 18.15% and 5.0% for snails in mountainous areas. However, no infection was found in the mountainous snails with inconvenient transportation. However, in the rural areas with convenient transportation, near the county seat or in the remote mountainous areas with inconvenient transportation Infection-positive mice were found. The mussels investigated did not find any infection. Conclusion The county has the natural foci of Guan Guan nematodes and its infection rate is high with a high degree of infection. At the same time, it was also found that the stone snail was also the intermediate host of C. elegans infection. It is easy to cause infection to local people, which should attract high attention and strengthen publicity and education.
