Yinchuan yueyahu Plague Surveillance 2004-2009

目的了解银川市兴庆区月牙湖长爪沙鼠鼠疫疫源地鼠密度、小型夜行鼠的种群构成、分布,为鼠疫疫情监测及防治对策提供科学依据。方法按照《全国鼠疫监测方案》,对捕获到的鼠进行梳检、细菌培养以及血清学检测。结果 2004-2009年月牙湖鼠密度为1.75只/公顷,小型夜行鼠捕获率为5.20%。2005、2009年两个年份在动物间发生鼠疫流行。结论长爪沙鼠是该地的优势种群,对鼠疫的发生流行起着决定性的作用;小型夜行鼠常常作为鼠疫自然疫源地的次要宿主或偶然宿主参与动物鼠疫流行过程,但小型夜行鼠成为沟通种间或种内群落间鼠疫流行的桥梁。
