Clostridium difficile is an extremely hardy bacteria that exists on surfaces and causes potentially life-threatening diarrhea. This represents a huge threat to hospitalized patients and those in longterm care or assisted living facilities. Unfortunately these bacteria can survive months on surfaces if not cleaned adequately. More and more academic and clinical groups across North America are seeing success in training dogs to detect the scent of C. difficile in the environment, leading to lower environmental burden and lower infection rates. Enter Percy, the 6 month old English Springer Spaniel. Percy is in training to become the first C.difficile detecting dog in Ontario. He will lend his services to both Kingston Health Sciences Centre, and longterm care facilities in the area. If successful, Kingston could be the host for an innovative training program to help others train dogs just like Percy.
