Brief Summary
The protocol aims to address the basic mechanisms of Clostridium difficile pathogenesis by identifying how a Th 17 response impacts severity of C. difficile infection and how Type II immunity protects the gut from Clostridium difficile toxin-induced damage. This could lead to new and effective approaches to the treatment or prevention of Clostridium difficile colitis that act downstream of fecal microbiota transplants (FMT) or next generation probiotics. Successful fecal microbial transplantation will restore protective immunity to recurrent C.difficile infection.
