the intestine.
Census of microbes in healthy humans reported
Some 200 U.S. scientists at Washington University School of Medicine in St. Louis and elsewhere detail findings from the most comprehensive census of the microbial make-up of healthy humans.
Virus works with gene to cause Crohn’s-like illness
Scientists have shown that a specific virus can interact with a mutation in the host’s genes to trigger disease. The observation may help explain why many people with disease risk genes do not actually develop disease.
