Fecal Microbiota Transplantation (FMT) involves the transfer of stool from a healthy donor into the gastrointestinal tract of a recipient. This procedure aims to restore the balance of gut microbiota, which can be disrupted due to various factors such as infections, antibiotic use, and chronic diseases. FMT is primarily used to treat recurrent Clostridioides difficile infection (CDI), which remains a significant public health challenge.
