Many Canadians live with debilitating chronic gut disorders such as Crohn's or ulcerative colitis (also known as inflammatory bowel disease, or IBD), Clostridium difficile infection (CDI), or both. These disorders lead to increased morbidity and reduce quality of life and productivity for patients and their families. One in every 150 Canadians has IBD, which is the highest rate worldwide. CDI is the number one cause of health care-associated infection (HAI) in Canada, and associated costs are approximately $300 million per year.
