Relationship of symptom duration and fecal bacteriotherapy in Clostridium difficile infection-pooled data analysis and a systematic review.

Objective: Clostridium difficle-associated infection (CDI) is usually treated with antibiotics; nevertheless, the infection has a high relapse rate. Case series and case reports using fecal microbiota transplant (FMT) for CDI show promising results. However, there are no large studies to provide evidence for the efficacy of this therapy.
