Core Tip

Core Tip: Fecal microbiota transplantation (FMT) is a promising therapy for restoring gut microbiota, with established success in recurrent Clostridioides difficile infection and emerging potential in dysbiosis-related diseases. Key methodological advancements, including improved donor screening, stool processing, and novel delivery methods like capsule-based formulations and live biotherapeutic products, have improved FMT’s safety and accessibility. Despite ongoing concerns about long-term safety and efficacy, future directions such as personalized FMT, synthetic microbiota, and microbiome engineering hold significant promise.
