Faecal microbiota transplantation (FMT) is an effective and safe treatment of recurrent Clostridioides difficile infection. It is essential to make every effort to perform FMT rigorously and based on scientific knowledge. Selection of the faecal microbiota donor is a key part of the process to ensure recipient safety. Protocols of action must be implemented that allow clinicians to act with the maximum guarantees and to minimise the risks of the procedure. In this regard, a multidisciplinary working group has been set up with the aim of establishing recommendations for selecting the faecal microbiota donor.
