Abstract: Objective Investigating bacterium in wild and domesticated Mongolian gerbil to establish Beijing local standard for control of bacterium in Mongolian gerbil.Method Wild Mongolian gerbil from Yinchuan city and Huhehot city and domesticated gerbil breeding in barrier system were euthanasied and anatomized.And then the bacterial flora of the cecum,trachea and larynx were isolated and cultivated by blood agar.After 18～24 h 37℃ cultivature,the bacterial colonies on the agar were classified and separated by singly colony.These singly colonies were identified by VITEK-32-auto bacterium analysis system.Result The wild gerbil from Yinchuan city and Hohehot city have 12 and 8 species,respectively.But the domesticated gerbil only has 7 species.Conclusion The bacterium isolated from wild Mongolian gerbil from Yinchuan city and Hohehot city have great differences in quantity,species and infection rate compared with laboratory gerbil from barrier system.These factors should be considered in establishing Beijing local standard for control of bacterium in Mongolian gerbil.
