Mice with Inflammatory Bowel Disease are Susceptible to<i>Clostridium difficile</i>Infection With Severe Disease Outcomes

Abstract

We, for the first time, demonstrate in an animal model that mice with dextran sulfate sodium induced-inflammatory bowel disease are significantly more susceptible to C. difficile infection, and that the bacterial infection led to more severe disease and death. These findings are consistent with clinical observations, thus, the animal model will permit us to study the pathogenesis of these concurrent diseases and to develop therapeutic strategies against the comorbidity of IBD and CDI.
