Scientists Develop a Way to Track Donor Bacteria After Fecal Microbiota Transplants

Researchers at the Icahn School of Medicine at Mount Sinai and their collaborators have developed a new technology to track beneficial bacteria after fecal microbiota transplants (FMT). The approach provides a detailed view of how donor microbes take hold and persist in the patients' gut--not only which bacteria successfully colonized but how they change over time. These insights may guide the design of safer and more effective microbiome-based therapies. The study was published in the October 22 online issue of Nature Microbiology [DOI: https://doi.org/10.1038/s41564-025-02164-8].
