NewsYour gut makes a molecule that fights a leading cause of food poisoning
Researchers have discovered that a molecule called indole can inhibit the growth of Campylobacter jejuni, a leading cause of food poisoning worldwide. Their study builds on years of research aimed at understanding how C. jejuni manages to thrive in the gut and cause disease.

NewsGut microbiome features predict devastating disease affecting preemies
In a discovery that challenges long-standing assumptions about necrotizing enterocolitis, researchers have identified previously unknown predictors for the disease. They found that bacteria-infecting viruses and bacterial antibiotic resistance genes in the gut microbiomes of babies are additional harbingers of necrotizing enterocolitis.

NewsFirst-of-its-kind preventative phage therapy provides promising results
The mammalian gut microbiome is teeming with a delicate balance of bacteria and the phages that keep them in check. What if the phages in the gut could prepare for an orally ingested pathogen and strike it down as it enters the gut, negating the need for a battle?

NewsFecal microbial signatures show promise for colorectal and pancreatic cancer assessment
Gastrointestinal and pancreatobiliary cancers can be difficult to detect early, creating a need for practical, noninvasive approaches for early detection and risk assessment. The gut microbiome has emerged as a potential source of cancer biomarkers, offering practical opportunities for noninvasive testing, as microbial changes can be assessed in fecal samples. ...

NewsBeyond the gut: Necrotizing enterocolitis drives neurodevelopmental impairment through gut-derived inflammation
A severe gut disease in premature infants, known as necrotizing enterocolitis (NEC), does far more than damage the intestines—it fundamentally alters brain development, leaving up to 40% of survivors with lasting cognitive, motor, and behavioral impairments.

NewsGut bacterial enzyme worsens colitis by switching off a protective intestinal signal
Microbiome research often focuses on which microbes are present in the gut and what small molecules they produce. But gut bacteria also make enzymes that can act directly on molecules produced by the host. Researchers report that one such bacterial enzyme can weaken a protective intestinal signal and aggravate colitis in a preclinical model.

NewsFecal microbiota transplantation may improve immunotherapy-related colitis
Targeting the gut microbiome with fecal microbiota transplantation may help cancer patients with immunotherapy-related colitis avoid the need for steroids and other immune-suppressing treatments, according to researchers.

NewsC. diff coordinates threat response to survive in gut
Researchers have discovered a unique system C. diff uses to simultaneously sense and respond to two different threats: host-mediated nutrient deprivation and a microbiota-produced antibiotic compound, suggesting new therapeutic options for preventing and treating C. diff infections.

NewsGut, airway and tumor microbes emerge as promising predictors of immunotherapy response in lung cancer
A comprehensive review systematically evaluates the microbiome’s role in lung cancer immunotherapy. Authors synthesized evidence covering microbial communities in the oral cavity, airways, lung tumors and gut, and their connections to treatment efficacy and immune‑related adverse events.

NewsProbiotic use surges - but microbiome-supportive food consumption stagnates
New research finds that probiotic supplement use has surged in the United States, while the consumption of microbiome-supportive foods has remained virtually unchanged. According to a study published in Clinical Gastroenterology and Hepatology, the consumption of probiotic supplements increased 287% among adults from 2009-2023 and 786% among ...

NewsVaccine protects against multiple fungal infections without hurting the gut
A vaccine created to battle multiple life-threatening fungal infections is successful in achieving protective immunity in pre-clinical animal models while also maintaining the biodiversity of the gut microbiome, according to a new study.

NewsSmall bowel microbiome offers clues to women’s health
A new study has identified differences in the makeup and organization of the small bowel microbiome between women and men. One intriguing finding was a bacterial community containing Granulicatella, found only in women.

NewsResearchers find C. difficile colonization in infants reshapes gut development
Practically since its discovery, the highly contagious bacterium Clostridioides difficile has been reported to not cause symptoms in infants. But new findings suggest that the bacterium can reshape the developing infant gut and may have long-term consequences.

NewsScientists discover link between gut bacteria and severe liver disease
Researchers have identified what may potentially be a missing link between specific activities in gut bacteria and the liver disease primary sclerosing cholangitis: the metabolite ImP, a molecule formed when certain gut bacteria break down dietary components.

NewsWhat happens when a shoreline scavenger consumes microplastics?
Researchers report on what happens when wharf roaches, a common shoreline scavenger, eat expanded polystyrene (EPS). Analysis of the wharf roach gut microbiome showed little change, but several rare microbes were found only in the EPS-fed specimens.

NewsInternational Society of Microbiota, Nature Awards and Yakult join forces to connect global funding with Japanese microbiome research
A new collaboration at ISM–RIKEN Targeting Microbiota 2026 will bring the Global Grants for Gut Health programme to Tokyo, alongside a dedicated funding discussion and three Best Abstract Prizes.

NewsThe body doesn’t just absorb a plant-based diet—it adapts to one, new review finds
A new review of plant-based diets concludes that the body actively adapts to sustained dietary change, absorbing iron more efficiently, synthesizing more of its own creatine and carnosine, using protein more economically, and remodeling gut bacteria to better ferment fiber.

NewsIndy gene reduction linked to healthier gut microbiota and longer lifespan in fruit flies
Scientists investigating aging have shown that Indy reduction is associated with lower bacterial load and higher bacterial diversity in aging Indy flies compared to controls.

NewsAntifungal therapy shows potential for IBD patients with candida overgrowth
A commonly used systemic antifungal medication may help reduce symptoms in a subset of patients with inflammatory bowel disease (IBD) by restoring a healthier gut microbiome, according to a preliminary study.
