NewsThe gut bacteria that put the brakes on weight gain in mice
Research has identified a specific type of gut bacteria, called Turicibacter, that improves metabolic health and reduces weight gain in mice on a high-fat diet. People with obesity tend to have less Turicibacter, suggesting that the microbe may promote healthy weight in humans as well.

NewsStudy reveals high stakes of early immune development—and a potential probiotic fix
Scientists find that certain gut bacteria are essential for building immune defenses during infancy, pointing to new strategies for protecting children’s health. They have identified a way to preserve healthy immune development even when infants need antibiotic treatment.

NewsGut bacteria from amphibians and reptiles achieve complete tumor elimination
Researchers have discovered that the bacterium Ewingella americana, isolated from the intestines of Japanese tree frogs (Dryophytes japonicus), possesses remarkably potent anticancer activity.

NewsA fatal mix-up: How certain gut bacteria drive multiple sclerosis
If gut bacteria are too similar to the protective layer of nerves, they can misdirect the immune system and cause it to attack its own nervous system. This mechanism can accelerate the progression of multiple sclerosis.

NewsHarmless Klebsiella strain shows powerful protection against gut infections in Inflammatory Bowel Disease (IBD) model
A new study demonstrates that a harmless strain of Klebsiella can eliminate infections and reduce gut inflammation in mouse models of inflammatory bowel disease (IBD).

NewsNovel kirkovirus may be associated with colitis in horses
In a pilot study, researchers have found a novel kirkovirus that may be associated with colitis – and potentially small colon impactions – in horses. The study could offer a route to new therapies for horses with colitis symptoms from unknown causes.

NewsStudy links gut bacteria to bloodstream infections in newborns within sub-Saharan Africa for the first time
New research has shown gut and bloodstream infections are caused by the same bacteria giving hope of better prevention and diagnosis of deadly neonatal sepsis.

NewsOpioid use linked to higher risk of C. difficile infection
New research from the University of Georgia suggests that opioid use could make patients more vulnerable to infections. The meta-analysis examined four studies of almost 120,000 patients. The researchers found that about 31% of patients who were prescribed and taking opioids caught C. diff, compared to 17% of patients who weren’t using them.

NewsNew review reveals how microbial communities accelerate the global spread of antibiotic resistance
A new scientific review has uncovered how complex microbial communities, including those in the human gut and the natural environment, act as powerful engines that drive the evolution and spread of antimicrobial resistance.

NewsHow polyphenol-rich diets promote healthy aging through microbiome and metabolome modulation
New findings suggest that polyphenol-rich diets can serve as a simple, safe, and effective nutritional strategy to counteract inflammation and support healthy aging.

NewsEverolimus alleviates ulcerative colitis via inflammation suppression and microbiota remodeling
A new study reveals how targeting the CLEC4E receptor and reshaping the gut metabolite axis offers a promising therapeutic avenue for inflammatory bowel disease.

NewsInside the gut: What our poo could tell us about our diet, gut microbes and health
Researchers have found that molecules in stool samples can accurately reflect what people eat and how their gut microbiome responds, offering a potential new tool to study nutrition and its impact on health.
-
NewsStudy unlocks the key microbes contributing to postnatal growth retardation
Postnatal growth retardation (PGR) has a high incidence during early postnatal development of piglets and humans. Researchers have found that hindgut-enriched Methanobrevibacter smithii compromises the weight gain in the pig PGR model.
-
NewsMajor breakthrough against diabetes thanks to a microbial molecule that disarms inflammation
Researchers have uncovered a surprising ally in the fight against insulin resistance and type 2 diabetes: a microbial metabolite called trimethylamine. TMA, produced by gut bacteria from dietary choline can block a key immune pathway and improve blood sugar control.

NewsThe power of gut enzymes: why healthy eating affects everyone differently
Researchers have uncovered a mechanism that determines how our gut microbiome processes healthful plant compounds. The chemical cookbook of gut bacteria varies from person to person—and is often disrupted in chronic diseases.
-
NewsAntibiotics could trigger immune response through gut microbiome metabolites
Researchers report how one of the most abundant gut bacteria responds to tetracyclines, a class of commonly prescribed antibiotics. Newly characterized signals released by the bacterium could aid the host’s immune response, inhibit pathogens and restructure the gut microbiome.

NewsProfessor named EMBO Young Investigator for work on the infant microbiome
Prof. Moran Yassour has been selected as one of the 2025 EMBO Young Investigators. She receives this prestigious recognition for her innovative research on the developing infant microbiome and its impact on pediatric health.
-
NewsStudy unravels the fungi-cancer connection
A growing body of evidence indicates that the microbiome within the gut and tumors significantly influences cancer initiation, progression, and treatment response. Current research primarily focuses on bacteria, whilst the role of fungi is only now gaining attention.

NewsProbiotics and prebiotics offer safer alternatives to antibiotics in animal agriculture
A new study shows how probiotics, prebiotics, and synbiotics can safely enhance growth and immunity in livestock, and balance the growth of intestinal microbes, offering practical alternatives to antibiotics.

NewsMucosal virome and host transcriptome interactions reveal viral influence in colorectal polyp development
A new study has provided the first integrated mucosal virome-transcriptome landscape of colorectal polyps, the precursors of colorectal cancer, offering new insights into viral-host interactions at this early disease stage.
