Content by Owlstone Medical LtdReviewed by Louis Castel The gut-liver axis is the term used to describe the two-way relationship between the gut microbiome and the liver. This relationship stems from the integration of signals produced by various factors such as diet, genetics, and the environment. The liver and the gastrointestinal tract are connected by...

by Nathalie Juge, The Conversation Credit: Pixabay/CC0 Public Domain Having a sweet tooth isn’t just a human characteristic. It turns out our gut microbes can have a preference for sweets, too—and one of these selfish, sugar-loving bacteria is Ruminococcus gnavus. Ruminococcus gnavus (R gnavus for short) is one of the many bacterial species normally found...
A newly discovered genetic arrangement may help a common bacterium in the human gut protect itself from a widely used antibiotic. Original story from The Marine Biological Laboratory Credit: Don Stalons/ CDC Antibiotic resistance is a significant and growing medical problem worldwide. Researchers at the Marine Biological Laboratory (MBL) and collaborators have found a novel...

DOI: 10.1016/j.immuni.2023.11.003The microbiome has a profound influence on our health, but exactly how our resident bacteria wield their power is still unclear. A type of T cell appears to provide some answers for gastrointestinal health, a study of the mouse microbiome finds. The study, appearing...

DOI: 10.1016/j.xcrm.2023.101051Researchers at the University of Toronto and its partner hospitals are finding that changes in gut microbiota after bariatric surgery can directly improve metabolism, independent of food intake, weight loss and other metabolic factors. Their ongoing work—including a study published in the...
by Dennis Thompson You may think that artificial sweeteners can help you lose some weight, but a new study finds they are no good for your gut’s microbiome. People who use aspartame (Equal), sucralose (Splenda), saccharin (Sweet’N Low), or stevia leaf extract tended to have intestinal bacteria colonies that differed significantly from those of people...
A common skin bacterium called Staphylococcus aureus can cause itchiness by acting directly on the nerve cells. DEPOSIT PHOTOSSHARE The itchiness that comes with some annoying dermatological conditions might be caused by certain microbes on skin. In a study published November 22 in the journal Cell, a team of scientists found that a common skin...
