In this study, a probiotic formulation based on\n                    <jats:italic>Enterococcus faecium<\/jats:italic>\n                    SF68 was administered to mice fed with a high-fat diet (HFD) to evaluate its efficacy in reducing body mass gain and in modulating the intestinal bacterial composition. Both stool and ileum samples were collected from untreated and treated mice and absolute abundances of specific\n                    <jats:italic>taxa<\/jats:italic>\n                    constituting the gut microbial\n                    <jats:italic>consortium<\/jats:italic>\n                    were evaluated. SF68 administration significantly reduced the HFD-induced weight gain.
