gut microbiome

Harvard Medical School researchers found that the gut bacterium *Morganella morganii* can contribute to depression by producing an inflammation-triggering molecule when exposed to the environmental contaminant diethanolamine (DEA).

A newly identified virus within a common gut bacterium shows a strong link to colorectal cancer, suggesting viruses in microbes may influence disease risk.
