目的 分析2010－2014年内蒙古地区各鼠疫疫源地鼠疫流行特点，为监测和防治提供科学依据。方法 根据2010－2014年内蒙古地区鼠疫监测结果，采用描述性流行病学方法进行分析。结果 内蒙古地区2010－2014年均有动物间鼠疫疫情发生，从3种宿主动物、4种媒介昆虫中共检出鼠疫菌166株；从4种宿主动物中检出阳性血清72份。结论 内蒙古地区近年来动物鼠疫疫情虽有所减缓，但局部地区仍十分活跃，仍需做好常规监测，防止发生人间鼠疫疫情。

Objective To analyze the enzootic plague epidemic characteristics of Inner Mongolia plague natural foci during 2010-2014, and provide a scientific basis for the future plague surveillance and control. Methods Collected plague monitoring data from 2010 to 2014 in the Inner Mongolia plague natural foci were analyzed using descriptive epidemiological method. Results It was found that there was prevalence of animal plague every year during the study period in Inner Mongolia. Yersinia pestis was identified in 3 kinds of host animals and 4 kinds of insect vectors, with positive serum samples detected in 4 kinds of host animals. There were 166 strains Y. pestis and 72 positive serum samples. Conclusion In the plague foci in Inner Mongolia, enzootic plague is still quite active and the surveillance should be strengthened to prevent human plague outbreak.
