After a large outbreak of post-infectious Inflammatory Bowel Syndrome in Walkerton, Canada, researchers have found a genetic link to susceptibility to the disease. Over 800 subjects, some infected and some controls, were compared, and three genes were found that can cause greater risk of IBS. The three genes involved cause a greater risk by causing a change in the way proteins that protect the intestines are encoded.
