Researchers have elucidated a mechanism by which ‘good’ bacteria that reside in our gastrointestinal tract can help protect us from inflammation, and how their disruption (dysbiosis) can increase the susceptibility of the liver to more harmful forms of disease. Their study identified two key metabolites produced by the bacteria in mice that modulate inflammation in the host and could ultimately reduce the severity of non-alcoholic fatty liver disease.

Scientists working with laboratory mice have shown that it’s possible to favor the engraftment of one gut bacterial strain over others by manipulating the mice’s diet. The researchers also have shown it’s possible to control how much a bacterium grows in the intestine by calibrating the amount of a specific carbohydrate in each mouse’s water or food.

Scientists have for the first time found evidence that a microbe in the human gut is associated with protection from typhoid fever infection. If the research is borne out, it could offer an exciting new way to reduce intestinal infections.
