New research suggests gut bacteria may be linked to high blood pressure and depression

A study of bacteria in the gut identified differences between people with high blood pressure compared to those with high blood pressure plus depression, according to preliminary research presented at the American Heart Association’s Hypertension 2019 Scientific Sessions. “People are ‘meta-organisms’ made up of roughly equal numbers of human cells Continue Reading

Micronutrients affect gut bacteria associated with ADHD in small but promising study

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, Continue Reading

Diarrhea-causing bacteria adapted to spread in hospitals

Scientists have discovered that the gut-infecting bacterium Clostridium difficile is evolving into two separate species, with one group highly adapted to spread in hospitals. Researchers at the Wellcome Sanger Institute, London School of Hygiene & Tropical Medicine and collaborators identified genetic changes in the newly-emerging species that allow it to Continue Reading

Precision editing of gut bacteria reduces cancer in mice

UT Southwestern researchers have shown that precision editing of the bacterial populations in the gut reduces inflammation-associated colorectal cancer in mice. The study published this week by the Journal of Experimental Medicine could lay the groundwork for novel cancer prevention strategies for individuals with chronic intestinal inflammation. Inflammatory bowel disease Continue Reading

Hospitals key in the spread of extremely drug-resistant bacteria in Europe

New research has found that antibiotic-resistant strains of Klebsiella pneumoniae, an opportunistic pathogen that can cause respiratory and bloodstream infections in humans, are spreading through hospitals in Europe. Certain strains of K. pneumoniae are resistant to the carbapenem antibiotics that represent the last line of defence in treating infections and Continue Reading

How do interactions between gut bacteria and fungi exacerbate crohn’s disease?

Scientists have known that bacteria in the gut, along with environmental and genetic factors, contribute to the debilitating intestinal ailment of Crohn’s disease (CD). But in 2016, Mahmoud A Ghannoum, Ph.D., FAAM, FIDSA, professor and director of the Center for Medical Mycology at Case Western Reserve School of Medicine and Continue Reading

These gut bacteria prevent mice from becoming obese—what could that mean for us?

Researchers at University of Utah Health have identified a specific class of bacteria from the gut that prevents mice from becoming obese, suggesting these same microbes may similarly control weight in people. The beneficial bacteria, called Clostridia, are part of the microbiome—collectively trillions of bacteria and other microorganisms that inhabit Continue Reading

Mosquitoes infected with natural bacteria to prevent reproduction will be released in Miami, in a non-GM effort to reduce mosquito populations

It might seem like scientists and other experts have all tried pretty much everything they can to eradicate pesky mosquitoes from the planet. But now, to fight Zika and other kinds of viruses carried by them, a new team of researchers based out of South Miami has decided to simply go Continue Reading

Researchers determine bacteria structure responsible for traveler’s diarrhea

For the first time researchers have deciphered the near-atomic structure of filaments, called ‘pili’, that extend from the surface of bacteria that cause traveler’s diarrhea. Without pili, these bacteria do not cause disease. Knowing this structural information may lead to the development of new preventive therapies for the disease. Traveler’s Continue Reading
