摘　　要：目的分析近年来嘉峪关市喜马拉雅旱獭鼠疫疫源地动物鼠疫流行特征,为下一步防治提供科学依据。方法运用描述性流行病学方法,对近几年鼠疫监测数据进行统计、分析与评价。结果 2008～2011年嘉峪关市旱獭密度为0.012～0.045只/hm2,体外蚤染蚤率58.64%～76.79%,蚤指数为1.82～2.31;洞干蚤染蚤率为7.60%～14.00%,蚤指数为0.21～0.48;分别于2009、2010、2011年从自毙獭及体蚤材料中检测出3株鼠疫菌和鼠疫F1抗原阳性4份。结论近年来甘肃省嘉峪关市喜马拉雅旱獭鼠疫疫源地动物鼠疫由"静息"转入活跃态势,需加大监测力度,密切注意鼠间疫情的动态,严防人间鼠疫发生。Objective To analyze epidemic characteristics of animal plague in Himalayan marmot plague foci in Jiayuguan in recent years,and provide a scientific basis for further prevention.Methods Descriptive epidemiology was taken to count,analyze and evaluate recent monitoring data.Results From 2008 to 2011,the marmot density was 0.012-0.045 ind./hm2 with infection rates of flea in vitro from 58.64% to 76.79% and flea index from 1.82 to 2.31,infection rates of burrow track flea from 7.60% to 14.00% and flea index from 0.21 to 0.48.Three strains of Yersinia pestis were isolated from dead marmot and body fleas collected from 2009 to 2011 with 4 samples of positive plague F1 antigen.Conclusions In recent years,animal plague in Jiayuguan Himalayan marmot plague foci turns from ＂resting＂ into the active posture.Efforts should be made to monitor and closely observe the dynamic of the epidemic among rats,and prevent occurrence of human plague.
