Use of frozen native feces for fecal microbiota transplantation in recurrent Clostridioides difficile infection: a simple way to improve the efficiency of donor feces preparation

Preparing fecal microbiota transplants immediately after donation is resource-intensive, and a proportion are destroyed following abnormal screening results. We retrospectively compared two processes, frozen fecal preparation (FFP) and fresh native frozen preparation (FNFP), for clinical efficacy in the treatment of recurrent
