Gut Bacteria

Scientists have found fecal transplants from old mice to young mice result in the younger animals displaying learning and memory impairments. The findings build on a growing body of research linking age-related cognitive decline with gut microbiome changes.

Researchers at the Mayo Clinic have developed a test, called the Gut Microbiome Health Index, that can predict a person’s general health status by measuring the levels of 50 gut microbial species.

A new study has identified a complex relationship between disturbed sleep patterns, elevated blood pressure, and disruptions to the gut microbiome. The findings could point to novel treatments to mitigate the negative health effects of poor sleep.

A first-of-its-kind clinical trial has found fecal transplants may be helpful reducing drinking behaviors in those suffering severe alcohol use disorder. The study points to a compelling relationship between the gut microbiome and addiction disorders.

Researchers from Ohio State University have created the first catalog of viral populations known to inhabit the human gut. Called the Gut Virome Database, the study suggests each person’s gut viral population is as unique as their fingerprints.

The bacteria that are present in a person's gastrointestinal tract can reveal a lot about their health. A newly developed capsule could provide even more information, by gathering bacteria from specific locations within that tract.

New research is describing how certain species of gut bacteria can enhance the efficacy of cancer immunotherapy. The animal study offers insights into a metabolite-immune pathway that could lead to microbial therapies incorporated into immunotherapy treatments.

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.
