The cells of simple organisms, such as bacteria, as well as human cells are surrounded by a membrane, which fulfills various tasks including protecting the cell from stress. In a joint project, teams from Johannes Gutenberg University Mainz (JGU) and Forschungszentrum Jülich, with participation of Heinrich Heine University Düsseldorf (HHU), have now discovered that a

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

Meat that is certified organic by the U.S. Department of Agriculture is less likely to be contaminated with bacteria that can sicken people, including dangerous, multidrug-resistant organisms, compared to conventionally produced meat, according to a study from researchers at the Johns Hopkins Bloomberg School of Public Health. The findings highlight the risk for consumers to

Latest remedy for eczema — rub bacteria on to your skin! Healthy strain of skin bacteria can effectively treat flare-ups in people with the most common form of eczema, studies suggest Scientists have developed an unlikely treatment for the dry skin condition eczema — a cream that is packed with human skin bacteria. Studies suggest

Adults with periodontitis transmit bacteria that can cause the disease in future to their children, and the bacteria remain in the oral cavity even when the children undergo treatment of various kinds, reinforcing the need for preventive care in the first year of a baby’s life. This is the main conclusion of a study conducted

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,

A rise in vaccine-resistant bacteria shows the need for a new vaccine to fight childhood empyema after a spike in hospitalizations, a new UNSW study reveals. Professor Adam Jaffe, Head of the School of Women’s and Children’s Health at UNSW Medicine & Health, said the research team's study was the first and largest of its

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

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

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.

A decade-long study has identified the factor produced by a common species of skin bacteria that triggers eczema, in a breakthrough of our understanding of the condition. The discovery of a missing link by an international team led by University of Manchester scientists could lead to new treatments for the sometimes debilitating skin condition which

In this episode of Life’s Little Mysteries, we’ll take a closer look at the mysterious single-cell microbes that are simpler than most other organisms, yet are still intriguingly complex: bacteria. What are bacteria and what do they look like? How long have bacteria been around? How do scientists study bacteria, and how do such simple

Could feces offer hope to survivors of spinal cord injuries? It’s a question University of Alberta physical therapy researcher Karim Fouad never thought he’d ask. But the expert in spinal cord injuries said the digestive tract could help explain the link between spinal injuries and changes in mental health, such as increased anxiety and depression.

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

Since the year 2012 has doubled the number of food alerts in Germany, more than. Especially in the case of milk and meat products, the cases are piling up. FOCUS Online explains what it is and what needs to change in the future, to ensure the safety of our food. Sausage, meat, dairy products: In

Our digestive tract hosts trillions of microbes, mainly bacteria, that help us digest food, make vitamins, strengthen the immune system, protect against germs, and produce molecules that affect many aspects of our health. Studying the microbial composition of the gut used to be extremely complicated. To identify them, they had to be cultured in the

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

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

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

Like humans, many bacteria like to spend time at the beach. The so-called flesh-eating bacteria, Vibrio vulnificus, don’t just like the beach; they need it, and rely on seasalt for survival. And as with human beachgoers, the warmer the water, the more of them there are. V. vulnificus is most commonly found in the warm
