目的调查内蒙古口岸地区鼠类分布及其携带病原体情况。方法 2014年5月至2015年4月,采用夹夜法捕获内蒙古口岸地区的鼠类并对其进行分类、分布调查,采用PCR或RT-PCR对鼠类样本进行鼠疫耶尔森菌(鼠疫菌)、伯氏疏螺旋体和汉坦病毒核酸检测。结果共捕获鼠类19种828只,其中五趾跳鼠、达乌尔黄鼠和黑线仓鼠(背纹仓鼠)数量较多,分别占捕获总数的27.05%(224/828)、23.19%(192/828)和17.39%(144/828),各鼠种分布差异明显。在长耳跳鼠中检测出鼠疫菌;黑线仓鼠(背纹仓鼠)、长耳跳鼠、五趾跳鼠和达乌尔黄鼠中检测出伯氏疏螺旋体;在黑线仓鼠(背纹仓鼠)、长耳跳鼠、小家鼠、五趾跳鼠和达乌尔黄鼠中均检测出汉坦病毒。结论内蒙古口岸地区鼠类分布广、种类多,存在鼠疫菌、伯氏疏螺旋体和汉坦病毒的自然感染,应加强鼠传疾病的监测和防控。
Objective To investigate the distribution of rodents in port area in Inner Mongolia and the status of pathogenic carriers. Methods From May 2014 to April 2015, rodents were captured in the port area of Inner Mongolia using the method of clip-nocturnal night-time to classify and distribute the rodents. PCR or RT-PCR was performed on the rodents of Yersinia pestis ), Borrelia burgdorferi and Hantavirus nucleic acid detection. Results A total of 828 species of 19 species of rodents were captured. There were many catches of 2728% (224/828), 23.19% 192/828) and 17.39% (144/828), respectively. Pseudomonas aeruginosa was detected in the long-eared jerk; Borrelia burgdorferi was detected in the black hamster (Back hamster), Long-eared jaundice, Pentacles and Daurian ground crab; Hamster), long-eared jerk, Mus musculus, Pentaphyllum, and Daurian ground crab hantavirus were detected. Conclusion There are a large number of rodents in Inner Mongolia, and there are many natural infections of Yersinia pestis, Borrelia burgdorferi and Hantavirus. The surveillance and prevention and control of rodent diseases should be strengthened.
