Gastrointestinal flora modulation

Gastrointestinal flora modulation refers to any deliberate intervention aiming to alter the composition or activity of the gut microbiota for clinical or health benefits[1][6]. The gut microbiota comprises bacteria, viruses, fungi, and archaea living in the digestive tract, and plays essential roles in host physiology, including digestion, immune function, and pathogen defense[5][7][9]. Modulation methods include administration of live beneficial microbes (probiotics), nutrients that foster targeted species (prebiotics), a combination of both (synbiotics), dietary changes, targeted antibiotics, phage therapy (using viruses to target specific microbes), and fecal microbiota transplantation[1][4][5][6]. Therapeutic modulation of gut flora is being investigated or used for a variety of diseases ranging from inflammatory conditions and infections to metabolic and neurologic disorders. Major safety concerns relate to the risk of infection, transfer of undesired traits (such as antibiotic resistance), and potential for adverse disruption of the microbial community. Because “Gastrointestinal flora modulation” is a strategy rather than a molecular target, it cannot be directly mapped to a canonical molecule or receptor.
