by German Center for Infection Research The bacterium Listeria monocytogenes can cause listeriosis, a life-threatening infection in animals and humans. Contaminated food is a frequent source of infection. Elderly people, people with a weakened immune system and pregnant women are particularly at risk with a mortality rate of up to 30 per cent. An international...

Microbiome provides new clues to determining development of colon cancer
by George Washington University A mutant protein found in humans with colon cancer blocks a pathway that regulates proliferation and expansion of cells, increasing amounts of bacterial species associated with the development of colon cancer. These findings, showcasing the connection between bacteria in the microbiome and colon cancer, were published by a team of researchers from...
Gut bacteria may enhance lifespan-extending effect of common diabetes drug
By Rich Haridy New research from an international team of scientists has revealed the effects of a commonly prescribed type 2 diabetes drug are regulated by metabolites produced by certain gut bacteria. The study offers compelling insights into how the microbiome can influence the efficacy of drugs, and more specifically the activity of a drug increasingly under the spotlight for its possible lifespan-extending effects....
Micronutrients affect gut bacteria associated with ADHD in small but promising study
by Kim Thomas, University of Otago Children with attention-deficit/hyperactivity disorder (ADHD) who took micronutrients had lower levels of a bacteria linked to the psychological disorder, and a healthier range of bugs in their gut overall, new research shows. The study was recently published in Nature’s Scientific Reports journal. It was a collaboration between University of Otago, Christchurch geneticists and...
People with fibromyalgia have different gut bacteria
By Catharine Paddock PhD Fact checked by Isabel Godfrey A study that compared women with and without fibromyalgia has, for the first time, linked gut bacteria to the long-lasting disease and its main symptoms. Researchers in Canada identified 19 species of gut bacteria that were present in higher or lower numbers in individuals with fibromyalgia. “We found,” says Amir Minerbi,...
Just a Phage? How Bacteria’s Predators Can Shape the Gut Microbiome
The gut microbiome is a complex, interconnected ecosystem of species. And, like any ecosystem, some organisms are predators and some are prey. A new study led by investigators at Brigham and Women’s Hospital and the Wyss Institute investigates the impact of bacteriophage, viruses that infect and kill bacteria. They find that phage can have a profound impact on the dynamics of the gut microbiome, not...
Unhealthy gut microbiome may make breast cancers more aggressive finds study
By Dr. Ananya Mandal, MD A new study from the researchers at the University of Virginia Cancer Center connects an unhealthy gut microbiome with breast cancer that can become invasive and spread to other organs faster. The results of the study were published in the latest issue of the journal Cancer Research. The study titled, “Pre-existing...
Bacteria and their Bearing on Bowels and Brain
Posted Today Microbiome’s effects on autism, inflammatory bowel disease explored. PNNL researchers today published a pair of papers, in Cell and in Nature, exploring the effects of the gut microbiome on our health, including autism, brain function, and inflammatory bowel disease. While scientists have known that the microbes that reside in us have far-reaching effects, the two...
