目的了解绥芬河口岸鼠、蜱感染人致病性巴贝虫情况。方法捕鼠选用中号钢板鼠夹,布于农田、林缘,晚放晨收;采集鼠体寄生蜱,用人工小时布旗法于林缘、苔草地采集游离蜱;采用PCR检测所获鼠、蜱人致病性巴贝虫DNA片段。结果捕获鼠50只,采集寄生蜱8只,游离蜱1 501只。绥芬河口岸鼠形动物巴贝虫感染率为32%,其中黑线姬鼠的感染率(11/33)与东方田鼠(4/12)均为33.33%;鼠形动物体表寄生蜱均为全沟硬蜱,其巴贝虫感染率为25%(2/8);游离蜱4种,为森林革蜱、全沟硬蜱、嗜群血蜱、日本血蜱,巴贝虫感染率为7.87%。结论绥芬河口岸存在人巴贝虫自然疫源地,该检测结果为下一步深入了解该病的性质及其流行病学特征提供了基础。
Objective To understand the pathogenesis of pathogenic Babesia in mice and ticks in Suifenhe Port. Method Trap selection of medium-sized steel rattrap, cloth in the farmland, edge of the forest, late morning release; collecting the parasitic ticks, using artificial hour cloth method in the edge of the forest, Carex grass collection of free ticks; , Ticks human pathogenic Babesia DNA fragment. Results Fifty mice were captured, 8 parasitic ticks and 1 501 free ticks were collected. The infection rate of rat-type Babesia was 32% in Suifenhe Port, among which the infection rate of Apodemus agrarius (11/33) and Oriental vole (4/12) were both 33.33%; the parasitic ticks The rate of Babesia crassi infection was 25% (2/8). Four ticks were tick-free, and the infection rate of A. epidermidis, Ixodes versicolor, B. violaceus, B. japonicus and Babesia was 7.87 %. Conclusion There is a natural foci of Babesia in Suifenhe Port. The results provide the basis for further understanding of the nature of the disease and its epidemiological characteristics.
