Fecal microbiota transplant
Fecal microbiota transplant (FMT), also known as a stool transplant, is the process of transferring fecal bacteria and other microbes from a healthy individual into another individual. FMT is an effective treatment for Clostridioides difficile infection (CDI). For recurrent CDI, FMT is more effective than vancomycin. Approximately 2000 procedures were performed in Europe in 2019. 
Side effects may include a risk of infections, therefore the donor should be screened. FMT involves restoration of the colonic microflora by introducing healthy bacterial flora through infusion of stool via colonoscopy, enema, orogastric tube, or by mouth in the form of a capsule containing feces from a healthy donor, which in some cases is freeze-dried.
