摘　　要：目的 研究近10年来广西隆林县鼠疫监测结果,为制订鼠疫防治对策提供依据.方法 收集2000-2009年广西隆林县鼠疫监测结果及鼠疫疫情资料,运用分析流行病学方法进行分析,计算鼠密度、鼠体染蚤率、蚤指数等指标,分析区域内鼠及蚤的构成.结果 2000-2009年,共捕鼠4829只,隶属2目3科11种,年平均鼠密度为3.30%（4829/146 206）,以黄胸鼠为优势鼠种（81.92%,3956/4829）;共检鼠体蚤4737匹,年平均鼠体染蚤率为27.99%（1351/4827）,平均蚤指数为0.98（4737/4827）,印鼠客蚤为优势蚤种（79.04%,3744/4737）;培养鼠4792只,分离出10株鼠疫杆菌.对2901份鼠血清进行间接血凝试验（IHA）,阳性2份;对1691份指示动物血清进行IRA试验,阳性24份.鼠疫累计发生在3个乡（镇）14个行政村的27个自然屯.结论 广西隆林县存在黄胸鼠鼠疫自然疫源地,鼠疫流行的风险仍然较高,应提高鼠疫监测的质量,增加指示动物的监测内容,尝试应用新技术.Objective To analyze the outcome of surveillance results on plague and to provide the evidences for the policy making in Longlin county Guangxi. Methods The epidemic data and the surveillance results of plague were analyzed and assessed with epidemiology methods in Longlin county Guangxi from 2000 to 2009, and the density of rodents, the rodents infected with flea, flea index and other indicators were calculated. Regional composition of the rats and fleas were analyzed. Results A totally of 4829 rats were captured and 4737 fleas were collected in the past 10 years, Rattus Flavipestus（81.92%,3956/4829） and Xenopsylla Cheopis （79.04%,3744/4737） were dominant species. The annual average density of rodents, the rodents infected with flea, index of flea were 3.30%（4829/146 206）, 27.99%（1351/4827） and 0.98（4737/4827）, respectively. A totally of 4792 rats were examined and 10 strains Yersinia Pestis were isolated. Indirect hemorrhagic assessed（IHA） was used to test the F1 antibody against plague in the blood serum of the rats and indicator animals, and 3 positive rats and 24 positive animals were found, respectively. Twenty seven natural villages in 3 towns had been involved in the plague. Conclusions The plague foci exists in Longlin county of Guangxi province. The plague foci in the areas have the same feature with the plague foci of Rattus Flavipectus. There is a potential risk for plague in this region, we should improve the quality of surveillance, increase indicator animals of the plague, and try to apply new surveillance method.
