Clostridium difficile infection is a major cause of nosocomial diarrhea. Its incidence has increased in the past 20 years and is associated with a significant morbidity and mortality. Relapsing is frequent after treatment and the management of these recurrent Clostridium difficile infections is challenging. Several studies over the years have shown that fecal microbiota transplantion is associated with a high degree of success. Fecal microbiota transplantion is now part of the European recommendations in the treatment of recurrent Clostridium difficile infections. However, standard procedures are needed to define indications, donor's selection criteria, preparation of the stool sample and its administration as well as the patients follow up.
