The World Health Organization says no evidence has emerged to show that a type of bird flu which has killed two Chinese men can be transmitted between people.
Two men in Shanghai, aged 87 and 27, fell sick in late February. A woman in Anhui province also contracted the virus in early March an... Read More
Slime molds may not have brains, but that isn't preventing some computer scientists from investigating them for their potential as novel, unconventional computers. A slime mold consists of a single cell containing millions of nuclei, and forms a network of protoplasmic tubes to move toward its f... Read More
U.S. malaria cases are at their highest level in four decades, mostly from Americans bringing home an unwelcome souvenir from their travels.
Malaria is not a big problem in the U.S. — there were only 1,925 cases in 2011, including five deaths. But cases were up 14 percent from the previous ye... Read More
Some 20 percent of of South Africans lack sustainable access to water. Many have to walk a third of a mile to get clean water from a standing pump, which is often shared with 100 or more other village residents.
That's why the South African government has invested in installing more than 23,000... Read More
An investigational vaccine appears generally well tolerated and effective against the most common strain of norovirus, reducing the main symptoms of the gastrointestinal (GI) infection, vomiting and/or diarrhea, by 52 percent, suggests research being presented at IDWeek 2013™.
Currently, ther... Read More
Visceral leishmaniasis, also called kala-azar, strikes 400,000 people every year and kills around 1 in 10 of its victims. The leishmania parasite, Leishmania donovani, has proven difficult to treat, in part because a large percentage of patients who take the drug of choice, miltefosine, relapse ... Read More
Researchers at Singapore's Institute of Bioengineering and Nanotechnology (IBN) and California's IBM Research -- Almaden (IBM) have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. They have successfully con... Read More
This video submission for the ASM Global Video Challenge highlights the impact of Salmonella-based vaccines on human health. Read More
Scientists are great at growing E. coli in the lab. They know exactly under which conditions various strains thrive. Unfortunately, there is only so much that can be learned from the bacteria’s behavior in an ideal, isolated and ultimately unrealistic environment. That is why a group of research... Read More
DNA carries out its activities "diluted" in the cell nucleus. In this state it synthesises proteins and, even though it looks like a messy tangle of thread, in actual fact its structure is governed by precise rules that are important for it to carry out its functions. Biologists have studied DNA... Read More
New research finds significantly higher levels of infectious pathogens in water from faucet taps with aerators compared to water from deeper in the plumbing system. Contaminated water poses an increased risk for infection in immunocompromised patients. The study was published in the February iss... Read More
Scientists are testing vaginal pessaries containing 'good' probiotic bacteria for the treatment of vaginal thrush. The research shows that this approach is likely to be a viable alternative to using precious antimicrobial drugs.

Researchers at Swansea University say a fungus could be the key to controlling mosquitoes.
Fungus Metarhizium anisopliae lives in soil and kills a whole range of insects and researchers say it also affects mosquito larvae if added to the water where the insect breeds.
The insects carry dis... Read More
In a classic case of turning an enemy into a friend, scientists have engineered a protein from flesh-eating bacteria to act as a molecular “superglue” that promises to become a disease fighter. And their latest results, which make the technology more versatile, were the topic of a report here to... Read More
Researchers have identified components in Clostridium difficile (C. diff) that may lead to new diagnostic tools, and ultimately more timely and effective treatment for this often fatal infection. C. diff is a spore-forming bacterium that causes severe diarrhea and is responsible for 14,000 death... Read More
The protein LIMP-2 is vital for both humans and animals. If it is absent – due, for example, to a hereditary disease – substances of an unknown nature, probably lipids, accumulate in the organism. Up to now, scientists were unsure what the protein looks like and how exactly it functions. Privatd... Read More
Small shifts in agricultural practices can increase or reduce the risk of salmonella and listeria contamination on produce, new research shows.
For example, applying manure within a year of harvesting produce boosts the odds of contaminating a field with salmonella, which is the biggest singl... Read More
A research team led by a molecular plant pathologist at the University of California, Riverside has discovered the mechanism by which an aggressive fungal pathogen infects almost all fruits and vegetables.
The team discovered a novel “virulence mechanism” — the mechanism by which infection ta... Read More
When attacking body cells, bacteria, such as salmonellae or Yersinia (plague pathogens), inject specific bacterial proteins through hollow, syringe-like structures – called injectisomes – into the host cells. These substances reprogram the cells and can thus overcome their defense. From then on,... Read More
A protein in Salmonella inactivates mast cells -- critical players in the body's fight against bacteria and other pathogens -- rendering them unable to protect against bacterial spread in the body, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS).
