【摘要】 目的在鼠疫历史疫区宜良县开展鼠疫监测,为鼠疫防治工作提供参考。方法按照《云南省鼠疫监测方案》等方案,采用笼夹法监测宜良县小型啮齿类动物、并梳检鼠体表面寄生蚤。结果共捕获鼠形动物1 552只,分属2目2科3属,褐家鼠为优势种占68.88%,黄胸鼠次之占25.39%。鼠体检蚤,鼠体染蚤率为36.40%,印鼠客蚤为鼠体优势蚤种占61.68%。6年室内平均鼠密度为2.04%,黄胸鼠鼠密度0.57%,室外平均鼠密度为2.42%,黄胸鼠鼠密度0.55%。平均黄胸鼠鼠体印鼠客蚤指数为0.85,黄胸鼠鼠体印鼠客蚤指数季节消长曲线呈单峰型,峰值为8月份。病原学和血清学监测均为阴性。结论 6年监测显示,主要宿主、主要媒介依然保持较高水平,1997年以后虽未再发现动物间鼠疫线索,但在大的自然环境、鼠种、蚤种的组成未发生根本性改变的情况下,鼠疫始终存在"复燃"的可能,我们要不断提高监测发现疫情的能力。更多还原

【Abstract】 Objective To carry out the monitoring work in historic animal plague area continuously and the result were analyzed.Methods According to Animal Plague Monitoring Plan In Yunnan Province,monitoring small sized glires animals and testing the flea.Results A total number of 1 552 mice were caught which are 2 orders,2 families and 3 genus.Rattus norvegicus was the dominant species and covers 68.88%,Rattus flavipectus covers 25.39%.Testing the flea,carrying rats were defected with a flea carrying rate of 36.40% and Xenopsylla cheopis was dominant species covering 61.68%.During 6 years of monitoring,the average density of indoor rested rodents was 2.04%,the density of Rattus flavipectus was 0.57%.The outdoor average density was 2.42%,the density of Rattus flavipectus was 0.55%.The average carrying defected rats with a flea carrying rate of 0.85%.Flea index of Rattus flavipectus shows unimodal in terms of seasonal variation of curve.Peak value was in August.No positive results were obtained.Conclusions Monitoring work be continuously carried out.Since 1997,no more information on the prevalence of animal plague to be found.But in case of no substantial change of general natural environment,mice species and flea species,plague is possibly coming back again.So we should instantly improve our capacity of monitoring plague situation.更多还原
