Most studies so far have focused on how the composition of the microbiome associates with health in general or various diseases

A review of studies suggests a potentially useful link between gut bacteria and mental disorders

Age also seems to be a factor, with younger guts more bacterially diverse (a good thing) than older ones

The findings suggest that the effectiveness and safety of probiotic therapies could change over time

A new study hopes to help understand the role of the microbiome in health and disease

The gut microbiota plays a key role in human health, and its composition is associated with diet

The human gut is home to trillions of microorganisms, mainly bacteria. Most of these are sensitive to antibiotics

What the latest studies mean for future clinical trials

Results show that gut microbiota could play a far greater role in the pathogenesis of MS than previously assumed

Hundreds of electricity-generating bacteria found, including pathogenic, probiotic, and fermenting bacteria
