Imagine a gut bacteria so strong that it resists antibiotic treatment. Clostridium difficile (C-diff) can be difficult to treat, but a new approach — fecal microbiota transplant — has shown promise. On the next Mayo Clinic Radio program, C-diff patient Stephanie Bennett and her physician, gastroenterologist Dr. Sahil Khanna, share the story of her successful fecal transplant. Also on the program, transplant surgeon Dr. Mikel Prieto explains how Mayo Clinic's Living Donor Kidney Program uses paired donation or a living donor chain to decrease the wait time for kidney transplant. And, infectious diseases specialist Dr. Stacey Rizza outlines the risk of being infected with hepatitis C, especially for people born between 1945 and 1965.
