摘　　要：目的 调查贵州省大型工程建设项目地区的鼠疫疫源状况,评估发生鼠疫的风险,为预防控制鼠疫提供依据.方法 2001-2011年,在贵州省14个大型工程建设项目地区的40个县（市、区、特区）,在每个县（市、区、特区）选择2～3个乡镇,在每个乡镇选择2～3个村（寨）,每个村（寨）采集5只指示动物的血清.调查居民室内及野外鼠疫相关的宿主动物和媒介蚤类,计算主要宿主动物密度、蚤指数;并对采集的标本进行鼠疫菌培养和血清学检测.结果 天生桥、平班、光照、三板溪、思林、董箐、黔中和沙沱水电站库区及兴义机场建设区域的居民住宅室内鼠疫主要宿主动物黄胸鼠密度为1.14％～3.87％;洪家渡、引子渡、构皮滩和龙滩水电站库区及金阳新区建设区域黄胸鼠密度为0.00％～0.84％;引子渡、平班、龙滩和光照水电站库区以及兴义机场建设区域总蚤指数分别为3.16、2.00、1.06、3.47和1.99.天生桥水电站库区检出鼠17份和蚤组4份鼠疫F1抗原阳性,鼠9份滤纸血和指示动物血清7份鼠疫F1抗体阳性,分离鼠疫菌3株.其他大型项目工程地区未检出鼠疫感染阳性指征.结论 天生桥水电站库区为现行鼠疫流行区,属于高度危险地区;平班、光照、三板溪、思林、董箐、黔中和沙沱水电站库区主要宿主动物黄胸鼠密度明显高于国家鼠疫控制标准,属于潜在危险地区.应继续加强鼠疫防治与监测工作,降低鼠疫发生的风险.Objective To investigate the status of the plague natural focus and assess the risk of plague in regions with large scale engineering construction project,in order to provide a basis for plague prevention and control.Methods The survey was carried out in 14 regions with large scale engineering construction project of 40 counties in Guizhou Province in 2000-2011,2-3 towns were selected in each county and 2-3 villages in each town,the plague hosts and flea vectors in the residential houses and outdoors were investigated,the sera of 5 animals were collected in each village.The capture rate of hosts and flea index were calculated.Then the samples were cultured and serological tested for plague.Results The density of rodents was 1.14%-3.87% in the reservoir region＆#39; residential building of hydro power station （Tianshengqiao,Pingban,Silin,Guangzhao,Sanbanxi,Dongqing,Qianzhong,Shatuo） and Xingyi airport,and Rattus flavipestus was the dominant species.The density of rodents was 0.00%-0.84% in the reservoir region of hydro power station （Hongjiadu,Yingzidu,Goupitan,Longtan） and Jinyang district; the total flea index in Yinzidu,Pingban,Longtan reservoir regions of hydro power stations were 3.16,2.00,1.06,3.47 and 1.99,respectively.A total of 21 rodent and flea samples from Tianshengqiao hydro power station were tested positive for F1 antigen of the plague.Three strains of Yersiniapestis were isolated.Nine rat filter paper blood samples and 7 sera of indicative animals were tested plague F1 antibody positive.Other regions with large scale engineering construction project were tested negative.Conclusions The reservoir region of Tianshengqiao hydro power station is endemic areas of the plague,where belong to high risk areas.The density of Rattus flavipestus is higher than the controlling standard of the country in the reservoir region of hydro power station （Pingban,Silin,Guangzhao,Sanbanxi,Dongqing,Qianzhong,Shatuo）,where belong to potential risk areas.The plague prevention and monitoring should be continual
