Commensal intestinal flora modulation

The term “commensal intestinal flora modulation” refers to any intervention or process that alters the composition, function, or activity of the indigenous microbes inhabiting the intestinal tract. These microbes are primarily bacteria but also include archaea, fungi, and viruses. Modulation of the gut microbiota can impact a broad range of host physiological processes including digestion, immune function, metabolite production, and disease susceptibility. Therapeutic modulation can be approached via probiotics, prebiotics, antibiotics, dietary interventions, and fecal microbiota transplantation. This is not a single molecular target but a collective term for a complex biological ecosystem whose balance and activity are central to health and disease.
