title: Isolation of Clostridium difficile from various colonies of laboratory mice.
abstract: An attempt was made to isolate Clostridium difficile from a total of 565 mice from nine different conventional mouse colonies and six different specified-pathogen-free mouse colonies. C. difficile was isolated from all the conventional colonies but from none of the specified-pathogen-free colonies. Ampicillin injected intraperitoneally increased the isolation rate of C. difficile from mouse faeces to 63.6% compared with 19.4% from untreated mice.
