Salmonella bacteria colonize the gut using intestinal epithelial cells

WHAT: The immune system's attempt to eliminate Salmonella bacteria from the gastrointestinal (GI) tract instead facilitates colonization of the intestinal tract and fecal shedding, according to National Institutes of Health scientists. The study, published in Cell Host & Microbe, was conducted by National Institute of Allergy and Infectious Diseases (NIAID) scientists at Rocky Mountain Laboratories

Good dental health may help prevent heart infection from mouth bacteria

Maintenance of good oral health is more important than use of antibiotics in dental procedures for some heart patients to prevent a heart infection caused by bacteria around the teeth, according to a new American Heart Association (AHA) scientific statement published today in the association’s flagship journal, Circulation. Infective endocarditis (IE), also called bacterial endocarditis,

When Should You Wet Your Toothbrush?

Brushing teeth is an important part of dental hygiene. A regular routine for teeth care is necessary for maintaining good dental health. Normally dentists recommend that you brush your teeth twice a day. The duration of brushing should last two minutes and the toothpaste you use should contain fluoride. However, this does not answer a

Hydrogen peroxide keeps gut bacteria away from the colon lining

Scientists at UC Davis Health have discovered that an enzyme in the colon lining releases hydrogen peroxide (H2O2) – a known disinfecting compound- to protect the body from gut microbes. Their study, published Dec. 9 in the journal Cell Host and Microbe, sheds light on the way microorganisms are spatially organized in the colon. It

Gut bacteria in multiple sclerosis: Probiotic or commensal, good or bad?

Researchers from the University of Vermont (UVM) have found that a bacterial species called Lactobacillus reuteri, commonly used in probiotics, can increase disease severity in a mouse model of multiple sclerosis (MS), an autoimmune disease that is the leading cause of non-traumatic neurological disability in young adults. But don’t throw away your yogurt just yet.

Study of intestinal bacteria of insects may reveal strategies for combatting them

More than half the world’s population runs the risk of contracting infectious diseases transmitted by mosquitoes in the next few years. With climate change, these so-called arboviruses—once a problem concentrated in the planet’s tropical regions—appear to also be occurring in places with a temperate climate. “Recent studies indicate that the bacteria present in the intestine

New strain of strep a is causing scarlet fever and invasive infections in England and Wales: Scientists warn vigilance is needed to monitor impact of new bacterial strain on public health

Scientists studying scarlet fever have identified a new strain of disease-causing bacteria, which may explain a rise in more serious Strep A infections in England and Wales, according to results from cases in London and across England and Wales from 2014-16 published in The Lancet Infectious Diseases journal. In 2014, England experienced the biggest surge

Mouthwash use could inhibit benefits of exercise

Exercise is known to reduce blood pressure — but the activity of bacteria in our mouths may determine whether we experience this benefit, according to new research. An international team of scientists has shown that the blood pressure-lowering effect of exercise is significantly reduced when people rinse their mouths with antibacterial mouthwash, rather than water

Rye is healthy, thanks to an interplay of microbes

Eating rye comes with a variety of health benefits. A new study from the University of Eastern Finland now shows that both lactic acid bacteria and gut bacteria contribute to the health benefits of rye. Published in Microbiome, the study used a metabolomics approach to analyse metabolites found in food and the human body. Rye
