绥芬河、东宁口岸地区鼠类感染新发蜱媒病原的检测

Detection of rodent infected by new tick pathogens in Suifenhe and Dongning ports

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 find out the situation of rodent infected by new tick pathogens in Suifenhe and Dongning ports. Methods Field investigation and epidemiological investigation methods were used in this study. Results Nine kinds of tick pathogens were detected in 102 rodent. The species infected were mainly Apodemus agrarius and Microtnsfortis. The main tick pathogen was Babesia microti and B. divergens, with the highest infection rate of 25.0%-27.3% and 33.0%-42.9% respectively, followed by Borrelia garinii and B. afzelii, with the infection rate of 21.2%-30.0% and 28.6%-33.0% respectively. The infection of tick borne encephalitis virus to rodent was the lowest, with the infection rate of 5.00%. Conclusion The rodent infected by tick pathogen were mainly A. agrarius and M. fortis in the two ports, which would provide the evidence for further epidemiological investigation.
