Efficacy and Safety of Fecal Microbiota Transfer (FMT) for Recurrent Urinary Tract Infections in Women

"FMT represents an ecological alternative for restoring the damaged intestinal ecosystem in this infection, increasing ecological diversity and thus limiting the spread of the pathogen. Recurrence of C. difficile is its only approved indication.~The impact of FMT on the intestinal ecosystem is attributable to intraspecific bacterial competition: commensal microorganisms (sensitive and non-virulent) have more effective growth rates than pathogenic bacteria (resistant and virulent), so FMT produces an ecological replacement in favor of grafting the donor microbiota and eliminating antibiotic-resistant clones."
