Each year, more than 300 million individuals are infected with malaria, a life-threatening blood disease caused by a parasite transmitted to humans by mosquitos. Whether malaria cases could be affected by warming climates has been a topic of debate, but now, researchers present the first evidence that the disease climbs to higher elevations during warmer years.

Experts at Public Health England (PHE) have launched a toolkit for hospitals to detect, manage and control antibiotic-resistant bacterial infections caused by carbapenemase-producing Enterobacteriaceae (CPE). The use of many different types of antibiotics in hospitals creates evolutionary pressures that encourage the development and spread of antibiotic resistant bacteria.

The report also found that, in hospitals, a 30 percent reduction in use of the antibiotics that most often cause deadly diarrhea infections with Clostridium difficile can reduce these infections by more than 25 percent. The same antibiotics also prime patients for future super-resistant infections.

For the first time, scientists have demonstrated the effectiveness of a small-molecule drug in protecting nonhuman primates from the lethal Marburg virus. Their work, published online in the journal Nature, is the result of a continuing collaboration between Army scientists and industry partners that also shows promise for treating a broad range of other viral diseases.

The bacterium Staphylococcus Aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to medical equipment, and if it gets inside the body, it can cause a serious and even life-threatening illness called a Staph infection. The recent discovery of drug-resistant strains of S.
When a person suffers a broken bone, treatment calls for the surgeon to insert screws and plates to help bond the broken sections and enable the fracture to heal. These "fixation devices" are usually made of metal alloys.But metal devices may have disadvantages: Because they are stiff and unyielding, they can cause stress to underlying bone.

The international consortium A-PARADDISE (Anti-Parasitic Drug Discovery in Epigenetics), coordinated by Inserm, has just obtained funds of €6 million from the European Commission to conduct large-scale testing of innovative therapies against four neglected parasitic diseases: schistosomiasis, leishmaniasis, Chagas disease and malaria.

New research from the US suggests an individual's particular mix of gut microbes may help the development of colorectal cancer tumors by interacting with genes and inflammatory responses.Colorectal cancer happens because healthy cells in the gut start to behave oddly following changes or mutations in their genes.

Using technologies and computational modeling that trace the destiny of single cells, researchers at the University of California, San Diego School of Medicine describe for the first time the earliest stages of fate determination among white blood cells called T lymphocytes, providing new insights that may help drug developers create more effective, longer-lasting vaccines against microbial...

Brisbane's water supply has been found to contain disease carrying bugs which can be directly linked to infections in some patients, according to a new study by QUT.Dr Rachel Thomson, who has completed her PhD through QUT's Faculty of Health, said certain species of nontuberculous mycobacteria were present in Brisbane's water distribution system.
An essential weapon in the body's fight against infection has come into sharper view. Researchers at Princeton University have discovered the 3D structure of an enzyme that cuts to ribbons the genetic material of viruses and helps defend against bacteria.
Porcine reproductive and respiratory syndrome (PRRS) is the most expensive and invasive disease for pig producers on a global scale. Though it is not occurring on every farm, it is the biggest disease problem in the pig industry, said a University of Illinois animal sciences researcher.E.

Researchers at the University of Missouri in the US have proved a "glow test" can detect the presence of deadly anthrax bacteria in hours instead of the usual days, promising to significantly cut the time it takes to respond to a potential bioterrorism attack.

Approximately one in five U.S. health facilities don't make alcohol-based hand sanitizer available at every point of care, missing a critical opportunity to prevent health care-associated infections, according to new research from Columbia University School of Nursing and the World Health Organization (WHO) published in the American Journal of Infection Control.
Immune system defenses against dangerous bacteria in the gut can be breached by turning off a single molecular switch that governs production of the protective mucus lining our intestinal walls, according to a study led by researchers at Yale, the University of British Columbia, and the Weizmann Institute of Science.
Shortly following the 9/11 terror attack in 2001, letters containing anthrax spores were mailed to news outlets and government buildings killing five people and infecting 17 others. According to a 2012 report, the bioterrorism event cost $3.2 million in cleanup and decontamination. At the time, no testing system was in place that officials could use to screen the letters.

To pull or not to pull? That is a common question when patients have the potentially dangerous combination of abscessed or infected teeth and the need for heart surgery. In such cases, problem teeth often are removed before surgery, to reduce the risk of infections including endocarditis, an infection of the inner lining of the heart that can prove deadly.

South Africa has been financing domestic rainwater harvesting tanks in informal low-income settlements and rural areas in five of that nation's nine provinces. But pathogens inhabit such harvested rainwater, potentially posing a public health hazard, especially for children and immunocompromised individuals, according to a team from the University of Stellenbosch.
