摘　　要：本文对市售獭皮的分类、单位面积带菌量、EV菌在市场獭皮上的存活时间及其与温、湿度变化的关系进行了研究。根据獭皮皮面有无脂肪,将獭皮分为干皮和脂皮。干皮单位面积平均带菌量为60.6万个菌/cm^2,鼠疫菌存活时间最长21天,最短14天,平均16.6天,与温、湿度变化呈明显的负相关关系;脂皮单位面积平均带菌量为715个菌/cm^2,鼠疫菌存活时间最长3天,最短0天,平均1.8天,与温、湿度变化无明显的相关关系。According to the marmot pelt with or without Fatty tissue, the peltry derided into two groups, namely, one is dry pelt, other is fatty's pelt. The experiment on survival period of Bacillus in the marmot pelt was conducted. The dry pelt were smeared it with 60.6 hundred Bacillus per cm^2, and then kept it at different temperature, 10, 20 and 30 degree centigrade. The result showed that the Bacillus could survived as longer as 21 days, and as shorter as 14 days, and 16.6 days on an average. The temperature is very strong factor for influence in survival of Bacillus. The fatty pelt was smeared it with 715 Bacillus per cm^2, the result show that it could lasted for as longer as 3 days, and 1.8 days on au average, No any influence in the temperature was founded.
