Abstract

Fecal microbiota transplantation (FMT) is considered as an effective treatment for Clostridioides difficile infection. However, the precise mechanism of FMT is yet to be determined. Human stool consists of the gut microbiota, bacterial debris, and metabolic products. Of these, the intestinal microbiota is the most important factor that exerts therapeutic efficacy in FMT. Fresh donor stool, blended with normal saline, has been employed for traditional FMT. Nevertheless, stool processing is a major impediment in FMT. Frozen stool and capsule formulations have similar efficacy to that of fresh stool. In addition, several novel stool products have been identified. A stool bank that provides stool products with pre-screened donor stool has been established to help physicians and thereby facilitate FMT. Recent next-generation sequencing techniques have been key in facilitating the detailed analysis of the microbiota and gut environment of individual donors and recipients.
