Bacteriophages in the gastrointestinal tract and their implications.


ABSTRACT: The gut microbiota plays an essential role in health and disease of humans. Bacteriophages are the most abundant members of the gut virobiota and display great diversity. Phages can translocate through the mucosa to lymph and internal organs and play a role as regulators of the bacterial population in the gut. Increasing abundance of phages in the gut mucosa may reduce colonization by bacteria. Moreover, phages may have an immunomodulatory role in the immune response in the human gut. The role of phages in inflammatory bowel disease (IBD) remains unknown. Phages may take part in the development of IBD, but there are also data suggesting the protective role of phages in the gut of patients with IBD. Furthermore, recent data suggest that phages may mediate the beneficial effects of fecal microbiota transplantation (FMT). Therefore, evidence is accumulating to highlight the protective immunomodulating activity of the gut phages.
