The biologist at the University of Sunshine Coast in Australia wants to understand why some animal species adapt well to urbanization, while others fall flat.

A review offers a glimpse of previously unconsidered variables that could hinder efforts to identify true correlations between disease and gut microbiome composition.

Tiny doses of maternal poo mixed with breast milk and given to Cesarean-born infants makes their gut microbiota resemble those of babies born vaginally.

A B-cell receptor critical for the production of a subset of intestinal antibodies has been pinpointed, but the function of those antibodies remains unclear.

The gut microbiome is more malleable in the first two years after birth, allowing probiotics to make their mark. Can we exploit this to improve infants’ health?

The microbial makeup of a newborn baby’s intestines has changed dramatically over the past 100 years, and we are now beginning to understand how and why this matters.

Most of the viruses present in people’s guts are bacteriophages, but how they interact with resident bacteria is still an open question.

Researchers find strains of the bacterium Klebsiella pneumoniae that produce high levels of alcohol in 60 percent of patients with the condition.

Research on hundreds of babies finds the delivery method is linked with a greater abundance of taxa more frequently seen in hospitals.

Physical activity, independent of diet, shifts the composition of bacteria in the intestines, spurring researchers to search for species that might provide benefits akin to working out.

An experiment delves into how the microbiome shapes immunity.

Molecules produced by resident bacteria and their hosts may signal immune cells to attack the body’s own tissues.

In a study of nearly 400 breastfeeding mothers, researchers find links between directly feeding the child and a more diverse microbiota, compared to milk from pumping.

Researchers find that it’s not just high-risk genes, but how children’s bodies respond to their own intestinal microbiota that relates to future diagnoses of type 1 diabetes.

Small microRNA-containing particles found in the plant can boost populations of healthy gut bacteria, and even improve colitis symptoms in mice.

A review finds that for several conditions, poop from certain healthy people is more likely to provide relief for recipients.

A case study of two patients with advanced cancer shows it might be possible to avoid a common and severe side effect of immunotherapy treatment.

As people move to the United States from Southeast Asia, the microbes in their digestive tracts begin to Westernize, possibly explaining high rates of obesity and other metabolic issues in these immigrant populations.

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