【摘要】 目的 了解廣州市鼠疫宿主動物及媒介的種群構成及數量分布情況，為鼠疫防治工作積累基礎資料。方法 采用夜籠法。對捕獲鼠類及撿獲蚤類進行鑒定，并計算鼠密度、鼠帶（染）蚤率和蚤指數；用鼠疫IHA 法檢測鼠疫F1 抗體。結果 捕獲鼠形動物1601 只，分屬2 目2 科4 屬7 種。其中嚙齒目動物1451 只，食蟲目動物150 只，總鼠密度（捕獲率）為12．09％，鼠密度（捕獲率）為11．50％；在242 只鼠形動物中發現染蚤鼠46 只，撿獲蚤92 匹，鼠體表蚤經鑒定為印鼠客蚤、貓櫛首蚤、緩慢細蚤、適存病蚤；鼠染蚤率為19．01％，總蚤指數為0．38；黃胸鼠蚤指數為0．63；未查出鼠疫F1 抗體。結論 褐家鼠仍是廣州市主要鼠種。主要蚤種是印鼠客蚤。未發現鼠間鼠疫流行跡象。
