NewsResearchers find a common weakness in major gut pathogens
The bacteria enterotoxigenic E. coli and Shigella together cause hundreds of millions of infections each year and are among the leading causes of diarrheal death, especially in children. A shared biological feature of these gut pathogens could lead to a vaccine that protects against both.

NewsDietary fiber supplement shows promise for fatty liver, with effects linked to gut microbiota
A study investigating the effects of prebiotic xylo-oligosaccharides (XOS) on fatty liver in humans suggest that the fiber supplement may reduce harmful metabolic byproducts in the gut and improve liver health. The composition of the gut microbiota prior to supplementation influences the benefits observed.

NewsCan probiotics help treat depression?
In a pilot clinical trial that included older adults with depression receiving standard care, adding probiotic therapy produced modest but meaningful reductions in depressive and anxiety symptoms compared with adding a placebo. However, both groups demonstrated substantial overall improvements during follow-up.

NewsStudy uncovers gut microbial patterns linked to Alzheimer’s disease in Puerto Rico - even showing up long before diagnosis
A new investigation into the links between Alzheimer’s disease and the gut microbiome in Puerto Rico has found specific gut microbial patterns associated with cognitive decline, disease severity and genetic risk factors.

NewsMaternal weight may influence microbiota signalling in amniotic fluid
New research investigates how maternal factors during pregnancy affect small particles produced by the body’s microbiota, giving insights into a new way to monitor maternal and fetal health during pregnancy.

NewsEffects of polystyrene nanoplastics and organophosphorus flame retardants on salamander gut-liver axis
New research reveals the effects of polystyrene nanoplastic and the organophosphorus flame retardant exposure on the gut-liver axis of salamanders.

NewsCohabitating people share about a quarter of their gut and oral microbiota
People who live together share more oral and gut microbes with each other than with other people in their communities, according to a study. Researchers also found a link between more transmissible microbes and health, particularly type 2 diabetes.

NewsYour gut talks to your liver: Study reveals how microbes influence liver function through DNA ‘switches’
Researchers have uncovered how the gut microbiome can influence gene activity in the liver by acting on short stretches of regulatory DNA that function like molecular “switches”.

NewsA gut bacteria molecule may calm intestinal inflammation by turning down cellular energy
A new study suggests enterobactin, a molecule produced by gut bacteria, could offer a new pathway for treating inflammatory bowel disease.

NewsGut bacteria linked to osteoporosis risk in primary hyperparathyroidism
Researchers studying primary hyperparathyroidism, a common endocrine disorder characterized by excessive secretion of parathyroid hormone, have identified Bifidobacterium longum as a potential microbial driver of bone loss through immune-mediated mechanisms.

NewsMolecular anchors on gut phages may open new avenues for therapeutic development
A new study has identified phage surface proteins acting as molecular anchors. These proteins confer phages with the ability to attach to human cells. Using genetic engineering, the researchers transferred these adhesion proteins onto the surface of another phage that otherwise lacked this ability.

NewsSugar-free diets may disrupt gut microbiome
Eliminating sugar from your diet may be more detrimental than previously thought, according to an animal study. Mice fed a sucrose-free diet developed impaired glucose control, insulin resistance, gut microbial imbalance, intestinal inflammation and fatty liver changes, despite having no significant differences in body weight compared with control mice.

NewsGLP-1s may alleviate depression in mice through the microbiome
Some people taking GLP-1 drugs for diabetes and obesity experience mental health benefits. In a mouse model study, researchers report that these improvements appear to result from gut microbiome changes that lead to an abundance of a microbe strain known to have a favorable effect on neurons related to stress.

NewsExpert tips: Why it’s best to eat more than one kind of fiber - and build up gradually
Fiber is an essential part of a healthy diet. By eating a variety of plant-based foods, increasing fiber intake gradually and staying well hydrated, you can support gut health and overall well-being while making fiber goals more achievable and sustainable. Purna Kashyap, M.B.B.S., a gastroenterologist at Mayo Clinic in Rochester, ...

NewsFood insecurity linked to gut microbiome changes in children
A new study shows that food insecurity may leave a measurable impact on the gut microbiome of children. Children in food-insecure households had different gut microbiome profiles, including higher levels of Sutterella, which has been linked to poor dietary quality and intestinal inflammation.

NewsResearcher studying probiotics to fight acid reflux and esophageal cancer
Patients with acid reflux, which occurs when stomach acid pushes up into the esophagus, know the symptoms all too well: heartburn, belching, chest pain and trouble swallowing. Acid reflux also increases the risk of esophageal cancer, but researchers are investigating how a simple probiotic could treat and prevent both conditions.

NewsÖtzi and his microbiome: a 5,300-year-old relationship
Researchers have obtained a detailed picture of the microbial community associated with the Iceman mummy Ötzi. The study provides insights into a complex microbiome, ranging from the gut flora of a Copper Age human to cold-adapted yeasts.

NewsThe brain, emotions, and the gut: How culture, stress, and social life shape gut health
A new study indicates that gastrointestinal health is influenced not only by genes, diet, and gut bacteria, but also by culture, social relationships, economic status, and the way individuals function within society.

NewsScientists recreate enterovirus infection in a new model of the human intestine
A miniaturized, biomimetic model of the human intestine successfully reproduced long-term enterovirus A71 (EV-A71) infection, report researchers. Using this innovative platform, they shed light on how this virus grows in the intestine without triggering a strong immune response.

NewsEngineered gut bacteria therapy emerges as scalable potential alternative to fecal microbiota transplants following clinical trial
Researchers have developed a new manufacturing platform for producing targeted mixtures of beneficial gut bacteria, an approach that could help expand access to microbiome-based therapies for patients with recurrent Clostridioides difficile (C. difficile) infection.
