目的了解黑龙江省绥芬河、东宁口岸地区鼠类感染新发蜱媒病原的情况。方法采用现场调查与分子流行病学调查手段,监测分析两地鼠类感染新发蜱媒病原的情况。结果对102只鼠类进行检测,发现有9种蜱媒病原,主要感染的鼠类为黑线姬鼠和东方田鼠;病原感染率高的是微小巴贝西原虫,分别为25.0%～27.3%和33.0%～42.9%;其次是莱姆病螺旋体,感染率分别达21.2%～30.0%和28.6%～33.0%;病原感染率较低的是病毒类森林脑炎,仅在东宁林区的2只黑线姬鼠中发现,感染率为5.00%。结论两地蜱媒病原的感染均以黑线姬鼠和东方田鼠为主。该检测结果为下一步深入了解这些疾病的性质及其流行病学特征提供了基础。
Objective To understand the pathogens of the newly infected ticks in rodents in Suifenhe and Dongning Ports of Heilongjiang Province. Methods Field investigation and molecular epidemiological investigation methods were used to monitor and analyze the pathogens of the newly diagnosed ticks in mice in two areas. Results 102 rodents were detected and 9 species of tick-borne pathogens were found. The main infected mice were Apodemus agrarius and Microtus fortis; the highest infection rate was Bombyx mori, which were 25.0% -27.3% And 33.0% -42.9% respectively, followed by Borrelia burgdorferi, the infection rates were 21.2% -30.0% and 28.6% -33.0%, respectively. The lower infection rate was viral forest encephalitis, Two black line Apodemus found that the infection rate was 5.00%. Conclusion The infection of tick-borne pathogens in both areas are mainly Apodemus agrarius and Microtus fortis. This test provides the basis for further insight into the nature of these diseases and their epidemiological features.
