目的了解高原鼠兔肝毛细线虫感染状况,探讨对人与家畜的危害。方法在甘肃省玛曲县尼玛镇、欧拉乡、金矿和大水等地区草场,通过徒手和粘鼠板捕获高原鼠兔,解剖肝脏,肉眼和光镜下观察。结果共捕获高原鼠兔209只,肝毛细线感染率为10.2%;其中尼玛镇草场鼠兔感染率18.0%,大水鼠兔感染率仅为5.1%。肉眼和镜下均观察到肝毛细线感染所致肝组织的损害。结论高原鼠兔是肝毛细线虫的宿主之一,为肝毛细线虫重要的储存宿主,提示在当地可能存在人体和家畜肝毛细线虫感染。
Objective To understand the infection status of Capillaria hepatica in plateau pika and explore the harm to human and livestock. Methods The plateau pikas were captured by freehand and sticky mouse plates in the areas of Nima, Oula, Jinli and Daishui of Maqu County, Gansu Province. The liver was dissected and examined under the naked eye and light microscope. Results A total of 209 plateau pikas were captured, and the rate of hepatic capillary infection was 10.2%. The infection rate was 18.0% in the nursery of Nimay town and only 5.1% in the rats of the large-sized zoo. Both liver and liver tissue damage caused by hepatic capillary thread infection was observed under the naked eye and the microscope. Conclusion The plateau pika is one of the hosts of the liver capillary nematode, which is an important storage host for the liver capillary nematode, suggesting that there may exist human and livestock hepatic capillary nematode infections in the area.
