New method helps speed up bacterial identification

Pinpointing the type of bacteria that are at the root of an infection in clinical samples removed from living tissues, such as blood, urine or joint fluids, to quickly identify the best anti-microbial therapy still poses a formidable challenge.

Scientists explore effects of physiological fluid shear on dangerous type of Salmonella

Once inside the human body, infectious microbes like Salmonella face a fluid situation. They live in a watery world, surrounded by liquid continually flowing over and abrading their cell surfaces--a property known as fluid shear.

Common angina drug can stimulate patient's own white blood cells to combat cryptococcosis

A drug, more commonly used in the treatment of angina, could be the focus of a new strategy in fighting the fatal fungal infection cryptococcosis

New systems-based strategy may help accelerate TB drug discovery

The rise in multi-drug resistant (MDR) and extremely drug resistant (XDR) strains of Mycobacterium tuberculosis (MTB) is becoming a major cause of global health concern for treating tuberculosis, which affects a third of the global population.

New study identifies PDGFRα as key molecule for HCMV viral entry

A publication in the scientific journal Nature Microbiology identifies PDGFRα as the receptor for the trimeric gHgLgO complex of Human cytomegalovirus (HCMV).

Scientists use X-rays to study how eculizumab prevents immune system from damaging kidney tissue

In collaboration with Alexion Pharmaceuticals, Inc., scientists from Aarhus University have used X-rays to understand how the therapeutic antibody eculizumab prevents our immune system from destroying red blood cells and damaging kidney tissue.

Scientists discover master dimmer switches that control activity of immune cells

A person's genetic makeup plays a role in autoimmune diseases such as multiple sclerosis that develop when the body is attacked by its own immune system. But little is known about how immune cells are pushed into overdrive.

Cigarette smoke promotes bacteria colonization, immune invasion

The mouth is one of the "dirtiest" parts of the body, home to millions of germs. But puffing cigarettes can increase the likelihood that certain bacteria like Porphyromonas gingivalis will not only set up camp but will build a fortified city in the mouth and fight against the immune system.

Cryptococcus research: an interview with Associate Professor Kirsten Nielsen

Cryptococcus is a fungus found in the environment throughout the world that is able to cause disease in humans. While most fungal pathogens don’t receive as much press as their bacterial or viral counterparts, they can be just as deadly.

Researchers demonstrate decisive role of cholesterol in T cell activation

T cell receptors are an important part of the human immune system. They are able to switch their conformation from an inactive to an active state spontaneously without any antigens present.

Meta-genomics analysis tool Taxonomer can rapidly and accurately detect pathogens

Scientists at the University of Utah, ARUP Laboratories, and IDbyDNA, Inc., have developed ultra-fast, meta-genomics analysis software called Taxonomer that dramatically improves the accuracy and speed of pathogen detection.

Drexel scientists identify how two new antimalarial drugs work

Drexel University scientists have discovered an unusual mechanism for how two new antimalarial drugs operate: They give the parasite's skin a boost in cholesterol, making it unable to traverse the narrow labyrinths of the human bloodstream.

Phage therapy in conjunction with antibiotics could help treat dangerous bacterial infection

Yale researchers were fishing for a new weapon against antibiotic resistance and found one floating in a Connecticut pond, they report May 26, 2016 in the journal Scientific Reports.

Malaria parasites use complement system to evade human immune response, study finds

The malaria parasite Plasmodium falciparum hijacks an immune system process to invade red blood cells, according to a study led by researchers at Penn State College of Medicine. Understanding how malaria invades the cells could lead to a more effective vaccine.

Single enzyme doing the work of a trio could offer precise way to treat diseases

Researchers identified a single enzyme doing the work of a trio thought necessary to control a common cellular signaling process being pursued as a therapeutic target.

NS5 viral protein could be promising vaccine target against Zika virus

A viral protein known as NS5 is a promising target for vaccines against Zika and related viruses, according to National Institutes of Health scientists and colleagues at Mount Sinai's Icahn School of Medicine.

New optimised PCR tests for reliable diagnosis of Zika virus

DZIF scientists from the University of Bonn have shown that not all conventional Zika virus molecular diagnostic tests for are sufficiently reliable. They developed optimised assays and a control for quantifying viruses in blood and urine.

Potential vaccine that resembles sugar structures may help fight against gut bacterium C. difficile

A vaccine against one of the most dangerous hospital germs may soon be available. Scientists from the Max Planck Institute of Colloids and Interfaces in Potsdam and the Freie Universität Berlin have developed a substance that elicits an immune response against the gut bacterium Clostridium difficile.

Pathogen-selective approach to antibiotic development less disruptive to gut microbiome

St. Jude Children's Research Hospital scientists report the first evidence that a pathogen-specific antibiotic was less disruptive to the gut microbiome than broad-spectrum antibiotics.

MGH researchers develop device to rapidly diagnose health-care-associated infections

A team of Massachusetts General Hospital investigators has developed a device with the potential of shortening the time required to rapidly diagnose pathogens responsible for health-care-associated infections from a couple of days to a matter of hours.
