Fecal microbiota transplantation as a possible treatment of irritable bowel syndrome

The human gut is composed of trillions of microbial organisms making up the microbiome. As our understanding of the composition of the human microbiome has advanced through developments in gene sequencing, its association with human physiologic function and disease has evolved. Alterations in the abundance of certain bacterial families have been noted in a number of intestinal diseases, and interventions to alter microbial ecology have impacted animal models of some diseases (1).
