Acute bouts of diarrhea could have lasting effects on the microbiota and host immune system activation, a mouse study suggests.

A new study finds that more than 200 human-targeted, non-antibiotic drugs inhibit the growth of bacterial species that make up part of the human microbiome.

Including microbiome composition in predictions of whether a person is obese can significantly improve their accuracy, according to an analysis.

Scientists are beginning to unravel the ways in which we develop a healthy relationship with the bugs in our bodies.

Rather than organizing into easily defined compartments, different microbes mix and intermingle within the mouse gut, scientists find.

Hundreds of samples from microbes living in the gut, skin, mouth, and vagina add to the human microbiome “fingerprint.” 

An oral mix of a pre- and probiotic can decrease deaths from the condition, according to the results of a large clinical trial conducted in rural India. 

Two research teams develop tools for tinkering with a bacterial genus prominent in human guts.

Two new techniques allow researchers to manipulate the activity of gut bacteria. 

Individuals who are more social and report feeling close with their families display similar gut microbes.
