The findings of a recent study suggest that the availability of iron can reshape the composition of the gut microbiota in irreversible ways.

The microbiota may promote sensory neuron regeneration

The findings of a recent study suggest that the microbiota can promote neuronal repair after tissue damage.

Some gut microbes may reverse diet-mediated protection against type 1 diabetes

The findings of a recent study may inform dietary interventions to help protect people against type 1 diabetes and other autoimmune diseases.

Study characterizes alterations of the gut microbiota in Crohn’s disease

The findings of a recent study advance our understanding of bacterial dysbiosis in Crohn’s disease and may inform new therapeutic strategies.

Specific gut bacteria reduce ovarian cancer progression in mice

The findings of a recent study tie the gut microbiota to immune surveillance of ovarian cancer and may inform new treatment approaches.

A mother’s gut microbes share genes with bacteria in the infant gut

A mother’s microbiota may shape the infant gut microbiota through horizontal gene transfer, in addition to the classical transmission of maternal bacteria to the infant’s gut.

Gut microbes may regulate motivation to exercise

The findings of a recent study suggest that signals derived from the gut can boost the motivation to exercise.

Gut microbes may help keep the blood-cerebrospinal fluid barrier intact

A recent study suggests that the blood-cerebrospinal fluid barrier is another barrier along the gut-brain axis that is likely influenced by the gut microbiota.

Microbiotas are transmitted between people that spend time together

A recent study suggests that people who spend time together share similar gut microbiotas — with some microbes being largely transmitted between friends and relatives.

New approach illuminates gut bacteria in living mice

The imaging approach can provide insights into the relationship between mice and their microbiota. It can also offer a glimpse of the cell wall turnover of gut bacteria in living…

Analysis of gut microbiota may predict disease severity in Chron’s patients

A recent study suggests that SCFA production is associated with a restoration of intestinal homeostasis and sustained remission in CD patients.

A nursing mother’s diet alters the microbiota of her offspring, mouse study finds

The findings of a new research suggest that a mother’s diet during nursing influences her offspring’s microbiota composition, gut health and predisposition to become obese.

The findings of a japanese research suggest that several viruses are linked to specific populations and diseases.

Gut microbes may mediate beneficial effects of low-carb diet on irritable bowel syndrome

Researchers have found that a diet low in fermentable carbohydrates can alter the human microbiota in ways that influence the expression of genes involved in inflammation and intestinal integrity.

How the tumor microbiota may reduce the efficacy of cancer drugs

A recent study confirms that 5-FU exerts part of its anti-cancer effects through inhibiting the growth of F. nucleatum, the commensal associated with colorectal cancer progression.

A closer look at the microbiota of the small intestine

A recent study confirms that ileum and colon have a distinct microbiota: unlike the bacterial composition of the colon, the ileum is subject to frequent fluctuations.
