摘要:目的 研究西林县鼠疫流行期间主要宿主动物和媒介蚤的特征，探讨鼠疫流行的危险因素。 方法 在2001年鼠疫流行期间对一、二和三类疫区采用笼捕法进行鼠密度调查，采用粘蚤纸法进行地面游离蚤调查，对捕获的鼠蚤进行分类鉴定。 结果 一类区黄胸鼠密度为5.73%，高于二、三类区的4.87%和4.77%;二类区的黄胸鼠体印鼠客蚤指数为0.14，明显低于一、三类区的0.98和0.93;一类区的地面游离蚤指数为0.06，明显高于二、三类区的0.0054和0。 结论 家鼠鼠疫疫区黄胸鼠和印鼠客蚤占总数的70%以上，当室内黄胸鼠密度大于5%及黄胸鼠体印鼠客蚤指数大于1等三项指标同时成立是鼠疫流行前期的预兆。
