New study shows how gut microbes can prevent severe flu infections in mice

Microbes that live in the gut don't just digest food. They also have far-reaching effects on the immune system.

Protein-rich diet may foster more tolerant, less inflammatory gut environment

Immune cells patrol the gut to ensure that harmful microbes hidden in the food we eat don't sneak into the body. Cells that are capable of triggering inflammation are balanced by cells that promote tolerance, protecting the body without damaging sensitive tissues.

Study finds high rates of drug resistance to urinary tract infections in Bangladesh

Organisms causing urinary tract infections (UTI) are increasingly proving to be ineffective or showing resistance to drugs that are used to kill the germs. This phenomenon has been increasing worldwide, especially to commonly used antimicrobials (drugs) in children.

Botulinum neurotoxin type X holds potential to open up new field of toxin therapeutics

Botulinum toxins are currently used on more than 80 medical conditions including Muscle spasms, Overactive bladder, Chronic migraine, Cervical dystonia, Sweating and Cerebral Palsy (CP).

When wounds won’t heal, therapies spread — to the tune of $5 billion

Carol Emanuele beat cancer. But for the past two years, she has been fighting her toughest battle yet. She has an open wound on the bottom of her foot that leaves her unable to walk and prone to deadly infection.

Mango intake exerts beneficial effects in progression and severity of IBD

Initial results of a study by researchers in the department of nutrition and food science at Texas A&M University in College Station show mango consumption has a positive impact on people with inflammatory bowel disease.

Kitchen sponges - play house for millions of bacteria - fresh study reports

Scientists in Germany have looked into the minute pores of a common kitchen sponge and found dreaded bacteria that could make us very ill. This is the first comprehensive study to do so. The study was published this week in Scientific Reports. Researchers write that humans spend most of their time in built environments or BE and the microbial presence in these environments is termed BE microbiome. These microbes may have a great impact on human health and wellbeing.

Vanderbilt researchers unravel how bacterial toxin prevents DNA replication

One of the most potent toxins known acts by welding the two strands of the famous double helix together in a unique fashion which foils the standard repair mechanisms cells use to protect their DNA.

TUM scientists provide new insights into development of T cells

When T cells encounter an antigen, they proliferate and produce various types of daughter cells. A team at the Technical University of Munich has now refuted the prevailing hypothesis that this immune response is largely predetermined by the individual structure of the T cell receptor.

Vanderbilt scientists find new way to destroy microbial vampires

On July 24 Vanderbilt scientist Eric Skaar, Ph.D., MPH, summarized his group's latest paper in a tweet: "If S. aureus is going to drink our blood like a vampire, let's kill it with sunlight."

Oral microbiome may help accurately determine time since death

Accurately determining the time since death is an important aspect of forensic sciences and casework. New research indicates that this might be achieved by examining changes in the bacterial communities of the mouth that occur after death.

Study finds current annual TB screening in North America to be costly with limited health benefits

Tuberculosis (TB) is a recognized hazard for healthcare workers, but the annual screening strategy currently in place in Canada and the United States is costly with very limited health benefits and should be reconsidered, according to a new study led by a team from the Research Institute of the McGill University Health Centre.

Walnuts may contribute to better health by changing makeup of gut bacteria

Research led by Lauri Byerley, PhD, RD, Research Associate Professor of Physiology at LSU Health New Orleans School of Medicine, has found that walnuts in the diet change the makeup of bacteria in the gut, which suggests a new way walnuts may contribute to better health.

Scientists uncover link between backup pathogen-fighting system and mutations in Crohn's patients

Genes that regulate a cellular recycling system called autophagy are commonly mutated in Crohn's disease patients, though the link between biological housekeeping and inflammatory bowel disease remained a mystery. Now, researchers at UT Southwestern Medical Center have uncovered an intriguing clue.
