    Antibiotic use from childhood linked to higher odds of IBS in young adulthood

    2026-10-19T10:33:00Z

    Antibiotic use from childhood through early adulthood was associated with higher odds of irritable bowel syndrome (IBS) at age 24, with the odds increasing as the number of antibiotic prescriptions rose, according to a new study.

    Scientists discover link between gut bacteria and severe liver disease

    2026-09-07T11:56:00Z

    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.

    Gut bacteria linked to frailty in older women

    2026-07-09T13:53:00Z

    Researchers have identified clear links between the composition of gut bacteria and frailty in older women. In cases of high frailty, with an increased risk of illness and death, gut bacterial diversity is lower and function is impaired.

    Antibiotics for common sore throats have very limited effect on Strep spread

    2026-06-04T09:06:00Z

    Antibiotics for sore throats have hardly any preventive effect against serious streptococcal infections in the population, according to a study. Instead, healthcare needs to quickly recognize warning signs of a serious infection.

    Gut microbiota plays a role in metabolic health after bariatric surgery

    2026-05-11T11:20:00Z

    Changes in gut microbiota after bariatric surgery are strongly linked to altered metabolic health and sustained improvement in type 2 diabetes. A study shows changes in gut bacterial composition and function are associated with metabolic improvements, including insulin release and blood sugar control.

    Immune cells in the nose slow influenza virus

    2026-04-28T10:33:00Z

    Memory cells in the nose slow the influenza virus as soon as it enters the body. They reduce viral levels and may help protect against more severe illness, according to a study that may help guide the development of better influenza vaccines.

    Early immune responses linked to protective HIV antibodies

    2026-04-22T09:02:00Z

    In a new study of broadly neutralizing antibodies and their potential for an HIV vaccine, researchers analyzed fragments of cell-free RNA and DNA circulating in the blood. This makes it possible to track immune responses, viral genetic variation, and other microbes from the same blood sample.

    Wastewater from most countries favours non-resistant bacteria

    2025-11-18T11:14:00Z

    Municipal wastewater contains a large range of excreted antibiotics and has therefore long been suspected to be a spawning ground for antibiotic-resistant bacteria. By testing the potential of untreated municipal wastewater from 47 countries to select for resistant E. coli, researchers show that while some samples indeed do so, most instead suppress them.

    Influenza virus hacks cell’s internal system

    2025-04-29T08:39:00Z

    The influenza virus manipulates the body’s gene regulation system to accelerate its own spread, according to researchers. Their study shows that an already approved drug could help strengthen immune defenses—though its effect in humans remains to be confirmed.
