Prolonged transfer of feces from the lean mice modulates gut microbiota in obese mice

摘要

BackgroundTransplanting a fecal sample from lean, healthy donors to obese recipients has been shown to improve metabolic syndrome symptoms. We therefore examined the gut microbiota in mice after administering a long-term, high-fat diet (HFD) supplemented with feces from lean mice through the fecal-oral route.
