The probiotic enhances donor microbiota stability and improves the efficacy of fecal microbiota transplantation for treating colitis

Abstract

L. plantarum GR-4 optimizes donor microbiota via pH-driven niche engineering, immunometabolic reprogramming, and bile acid modulation, addressing key limitations of conventional FMT. The multi-targeted efficacy of MFMT, evidenced by superior remission rates and metabolic restoration, establishes this approach as a translatable strategy for IBD therapy. This study establishes probiotic-enhanced FMT as a paradigm for precision microbiome interventions.
