Using wild mice housed in laboratory conditions, researchers find that gut bacteria compositions change little from one generation to the next.

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.

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

The composition of the gut microbiota varies by time of year and is more diverse than that of industrialized groups.

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.
