New study reveals 80% of stethoscopes are contaminated with infectious bacteria

There are now two reasons for patients to flinch at the touch of a stethoscope: because it's cold, of course; and because it's covered with germs.

Scientists shed light on evolutionary history of multidrug-resistant enterococci bacteria

Enterococci bacteria are the bane of hospitals, causing thousands of multidrug-resistant infections in patients each year.

Study: Drug-resistant tuberculosis predicted to increase in four high burden countries

Cases of drug-resistant tuberculosis are forecasted to increase in the four high burden countries (India, the Philippines, Russia, and South Africa) between 2000 and 2040, with the upturn likely to be a result of increased transmission of drug-resistant tuberculosis between people, rather than by strains acquiring resistance to anti-tuberculosis drugs, according to a study published in The Lancet Infectious Diseases.

Scientists discover natural defense mechanism that kills TB bacteria

A natural mechanism by which our cells kill the bacterium responsible for tuberculosis (TB) has been discovered by scientists at the Francis Crick Institute, which could help in the battle against antibiotic-resistant bacteria.

Gut microbiome may play key role in pathology of common cerebrovascular disease

Bacteria in the gut microbiome drive the formation of cerebral cavernous malformations (CCMs), clusters of dilated, thin-walled blood vessels in the brain that can cause stroke and seizures, according to new research published this week in Nature by researchers from the Perelman School of Medicine at the University of Pennsylvania.

Cosmetic makers harness microbiome to help treat skin conditions

Cosmetic companies have started developing and selling products designed to harness the skin microbiome to help treat a range of skin conditions from acne to eczema.

Study identifies conservation management activities that could affect Lyme disease risk

Lyme disease – an infection contracted from the bite of an infected tick– is an important emerging disease in the UK, and is increasing in incidence in people in the UK and large parts of Europe and North America.

Swiss researchers discover potential way to design new antibiotics

Two Swiss research teams from the University of Bern and the ETH Zurich have developed a new method to shed light onto a mostly unknown process of bacterial protein production. Their results could be used for the design of new antibiotics.

Scientists study cell’s reaction to Salmonella by visualizing protein chains at near-molecular level

With drug resistance being on the rise worldwide, bacterial infections pose one of the greatest global threats to human health. By deciphering the host-pathogen interaction on a molecular level, researchers hope to pave the way for new therapies.

Natural compound in grape seed extract could increase strength, life of composite-resin fillings

A natural compound found in grape seed extract could be used to strengthen dentin -- the tissue beneath a tooth's enamel -- and increase the life of resin fillings, according to new research at the University of Illinois at Chicago College of Dentistry.

Most Philadelphia home kitchens contain at least one foodborne pathogen, study finds

If held to the same standards as restaurants in the area, most Philadelphia home kitchens examined for a pair of Drexel University studies would receive "critical code violations."

Researchers discover that microRNA can prevent excessive intestinal inflammation

An international team of researchers has discovered that a microRNA produced by certain white blood cells can prevent excessive inflammation in the intestine.

Novel nanoscale molecular slingshot could ‘shoot’ and deliver drugs at precise disease locations

An international team of researchers from the University of Rome Tor Vergata and the University of Montreal has reported, in a paper published this week in Nature Communications, the design and synthesis of a nanoscale molecular slingshot made of DNA that is 20,000 times smaller than a human hair.

Breast-feeding transfers beneficial bacteria to the baby’s gut, new study finds

Mothers protect their babies and teach them habits to stay healthy and safe as they grow. A new UCLA-led study shows that beneficial bacteria from mothers do much the same thing.

Study uncovers potential new therapeutic targets for HCV infections

An international study led by researchers at Monash University' Biomedicine Discovery Institute (BDI) has shone light on the way the Hepatitis C Virus (HCV) hijacks the communication systems in the host cells it infects, uncovering potential new therapeutic targets for the disease.

Study shows how influenza A hijacks human cellular machinery to replicate

Much is known about flu viruses, but little is understood about how they reproduce inside human host cells, spreading infection. Now, a research team headed by investigators from the Icahn School of Medicine at Mount Sinai is the first to identify a mechanism by which influenza A, a family of pathogens that includes the most deadly strains of flu worldwide, hijacks cellular machinery to replicate.

Dendritic cells develop from specialized progenitors, research shows

Dendritic cells are gatekeepers of Immunity and are crucial for the detection and initiation of Immunity against pathogens and foreign substances. Up to now dendritic cell subtypes were thought to develop from one common progenitor.

Researchers discover new defense mechanism against bacteria during wound healing

Researchers in dermatology at Lund University in Sweden believe they have cracked the mystery of why we are able to quickly prevent an infection from spreading uncontrollably in the body during wounding. They believe this knowledge may be of clinical significance for developing new ways to counteract bacteria.

Children with bloodstream infections less likely to die than adults, study shows

Children with bloodstream infections caused by methicillin-resistant Staphylococcus aureus, a common antibiotic-resistant bacteria, are less likely to die than adults with this condition and have different risk factors for treatment failure, a new study led by a Children's National Health System clinician indicates.
