摘要
目的研究近12年来广西隆林县鼠疫监测结果,为制定鼠疫防治对策提供依据。方法运用分析流行病学方法和医学统计学技术,对2000-2011年广西隆林县鼠疫监测结果进行统计、分析和评价。结果 12年中共捕获鼠类6064只,隶属2目3科11种,年平均鼠密度为3.21%,以黄胸鼠为优势鼠种;共检鼠体蚤5865匹,隶属6种,年平均鼠体染蚤率为26.59%,平均蚤指数0.97,印鼠客蚤为优势蚤种;培养鼠6030只,分离出10株鼠疫菌,对3663份鼠血清进行间接血凝试验(IHA),检出阳性血清2份,阳性率为0.05%,对1792份指示动物血清进行IHA试验,检出阳性血清24份,阳性率为1.34%。结论综合地理、宿主动物、媒介蚤及病原体等因素分析认为,广西隆林县存在黄胸鼠鼠疫自然疫源地;进一步加强鼠疫监测是防治鼠疫的重要手段。
Objective To analyze the plague surveillance results in Longlin county,Guangxi,China from 2000 to 2011,and to provide a basis for the prevention and control of plague.Methods Analytic epidemiology and medical statistics were used for the statistics,analysis,and evaluation of the plague surveillance results in Longlin from 2000 to 2011.Results During the past 12 years,a total of 6064 rats,belonging to 11 species in 3 families of 2 orders,were caught,with an annual mean rat density of 3.21%,and Rattus tanezumi acted as the dominant species;a total of 5865 rat fleas,belonging to 6 species,were collected,with an annual mean rat flea-carrying rate of 26.59% and a mean flea index of 0.97,and Xenopsylla cheopis was the dominant species.A total of 6030 rat samples were bred,and 10 Yersinia pestis strains were isolated.Indirect hemagglutination test was used to examine 3663 rat sera and 1792 indicator animal sera.Two positive rat sera（0.05%） and 24 positive indicator animal sera（1.34%） were obtained.Conclusion There is natural epidemic focus of R.tanezumi in Longlin county,according to the analysis considering geography,host animals,vector fleas,pathogens,and other factors.Plague surveillance must be strengthened to prevent the prevalence of plague.
