Gastroenterology is the official journal of the American Gastroenterological Association (AGA) Institute. "We are beginning to understand the ways by which the microbial environment of the gut may play a role in both the maintance of human health and the development of certain diseases. Data in this special issue of
may lead to strategies for the prevention and treatment of a number of diseases, " stated Gary Wu, MD, guest editor for the special issue; chair, scientific advisory board of the AGA Center for Gut Microbiome Research and Education, and professor of medicine, Perelman School of Medicine at the University of Pennsylvania, Philadelphia.
Reflecting the evolution of intestinal microbiome research, the articles in this special issue address three themes: 1) basic concepts in the mammalian gut microbiome; 2) gut microbiome and disease; and 3) modification of the gut microbiome to maintain health or treat disease.

"By focusing this issue of Gastroenterology
on the intestinal microbiome, we strive to provide comprehensive and up-to-date research on the human gut microbiome and its association with health and disease," note Chung Owyang, senior associate editor of Gastroenterology
. "We hope to stimulate research that will lead to further discoveries and novel treatments."
Environmental factors play a large role in the significant rise of a number of human diseases, especially those effecting residents of industrialized nations, such as inflammatory bowel disease and metabolic disease. These factors, in combination with a person's genetics, appear to play a prominent role in shaping the composition of the gut microbiota. Recent advances in technology, especially in DNA sequencing and bioinformatics, have enabled scientists to better characterize the microbes that inhabit the human gut and, potentially, how they may play a role in disease pathogenesis.
