Abstract
The present invention relates to immunogenic compositions comprising isolated Clostridium difficile CDTb and/or CDTa protein. In particular the isolated Clostridium difficile CDTb protein is suitably a truncated CDTb protein comprising the receptor binding domain or a mutated CDTb protein incapable of binding to CDTa, and the isolated Clostridium difficile CDTa protein is suitably a truncated CDTa protein which does not comprise the C-terminal domain. In particular the invention also relates to fusion proteins comprising a CDTa protein and a CDTb protein and also fusion proteins between an isolated Clostridium difficile toxin A protein and/or an isolated Clostridium difficile toxin B protein fused to a CDTb protein.
