Gut Bacteria

New research suggests a high-fat diet and antibiotics work together to promote a gut microbiome imbalance that can lead to bowel inflammation. The study sheds light on the causal mechanism by which environmental factors can trigger IBD.

Researchers have for the first time studied the gut microbiome of subjects with prediabetes, revealing a person’s unique gut bacteria population could be used to predict their likelihood of developing type 2 diabetes.

A research team working to unravel the secrets of the gut microbiome has happened upon a specific signature of bacterial species that can be used to detect liver fibrosis and cirrhosis with an accuracy of greater than 90 percent.

New research from the University of Colorado Boulder has offered some of the clearest evidence to date showing how the gut microbiome produces a metabolite that, over time, contributes to age-related declines in cardiovascular health.

New research from the University of Massachusetts Amherst is adding weight to a growing body of evidence suggesting the food additive titanium dioxide, also known as E171, can disrupt the gut microbiome, leading to colonic inflammation.

Two new studies are offering strong evidence that bowel inflammation and obesity are risk factors for developing dementia. The studies are observational, and cannot determine causality, but they build on prior research reaching similar conclusions.

A new study has strengthened ties between Parkinson's disease and the gut, identifying a type of overabundant pathogen in Parkinson’s disease patients that opens up new lines of enquiry in understanding the root causes of the condition.

A new study, led by researchers at the Broad Institute of MIT and Harvard, is shedding light on a century-old mystery. The study describes how bacteria in the gut can metabolize cholesterol at levels high enough to improve a person’s cardiac health.

Building on the growing link between poor oral health and gastrointestinal disease, research from the University of Michigan has homed in on the possible mechanisms by which periodontitis can exacerbate the gut inflammation seen in patients with IBD.

A new study has delved into the impact of gut bacteria on cholesterol levels, detailing the "remarkable effects" of the introduction of a set of molecules that shift the balance of bacterial species in a way that prevents thickening of the arteries.

A new study has demonstrated the profound influence diet and gut bacteria have on the effectiveness and toxicity of drugs used in chemotherapy. The research concludes the complexity of drug, diet, and bacteria interactions in humans is “astronomical.”

A study is offering the first evidence of a causal link between gut bacteria and neurovascular disease. It suggests a microbial metabolite can travel through the bloodstream, reach blood vessels in the brain and expedite the development of lesions.
