Gut-microbes are key regulators of host’s life span and ageing

Gut microbes impact host physiology, affecting health status, and imbalance of the gut microbial commensal communities is associated with disease. Re-establishment of a healthy gut microbial composition can resolve acute and life-threatening bacterial infections. Recent work using the short-lived African turquoise killifish (Nothobranchius furzeri) indicates that gut microbes from young individuals can modulate the general health status and life span in healthy ageing subjects.
