Every day, millions of microorganisms reach Spain from the Sahara Desert and the Sahel region – by flying. Louis Pasteur demonstrated back in 1861 that germs can move through the air, but it was only recently discovered that bacteria, funguses and viruses can travel thousands of kilometers stuck...

The Department of Health here has cautioned villagers to be vigilant against dengue fever amid a reported 6 deaths during the 1st months of the year . The reported dengue deaths from January to June this year is higher than the 5 recorded during the same period in 2009. The dengue deaths ... Read More
Current methods of diagnosing an infectious disease can take days to weeks. Now a Cambridge, MA-based startup called Pathogenica is developing a way to do it within a day--by reading the DNA sequence of pathogens.
Pathogenica is developing diagnostic tests designed to detect harmful microorga... Read More
In biology and genetics, the concept of epistasis is what gives rise to the whole being more (or less) than the sum of its parts. The quantitative effect of a given mutation upon the traits of an organism has the potential to depend strongly upon the gene versions present in other parts of the g... Read More
Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.
Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimatel... Read More
It is widely accepted that the shift in case-fatality rate between waves during the 1918 influenza pandemic was due to a genetic change in the virus. In animal models, the infectious dose of influenza A virus was associated to the severity of disease which lead us to propose a new ... Read More
Buruli ulcer is an infectious disease afflicting thousands of children every year. The difficult-to-cure disease, which is caused by bacteria, occurs in tropical or subtropical climate zones and results in open sores and deformities. For the last two years, the international research consortium ... Read More
Hikers may be locked out of hundreds of caves and 30 000 abandoned
mines in the West and Midwest in a government plan to protect bats
The cave closings may come within the week, said Forest Service
spokeswoman Janelle Smith, and are the latest efforts to combat a
disease... Read More
First, you may be asking yourself – Why viral bioinformatics? Good question! Although it’s true that much in the world of bioinformatics can be applied to all manner of protein and DNA sequences, there are a number of resources that are specific for viruses and there are a number of analyses tha...

One of my big headaches at the moment is a patient — call him Ralph — who appears to be one of the most successful small-time alchemists in all of New York.
He creates gold from dross modern-style, filling his prescriptions every month like clockwork and then selling the unopened bottles for... Read More
A team of scientists, led by Mauro Delogu, virologist from the Veterinary Faculty of the Bologna University and researchers from the Istituto Superiore di Sanità, Istituto Zooprofilattico Sperimentale della Lombardia e dell'Emilia and St. Jude Children's Research Hospital (Memphis, Tennessee) ha...

Electronic surveillance is becoming a critical tool in an infection preventionist's arsenal of tools with which to fight healthcare-acquired infections (HAIs). ICT presents the following case studies to highlight the benefits of using informatics in infection prevention and control efforts.

Human history marches to the beat of what? A big brass band? A choir singing hymns? The lub-dub of the human heart? Sonia Shah’s tour-de-force history of malaria will convince you that the real soundtrack to our collective fate is none of these: it is the syncopated whine-slap, whine-slap of ma... Read More
Biologists have demonstrated a connection between multiple sclerosis (MS)—an autoimmune disorder that affects the brain and spinal cord—and gut bacteria.
Details of the findings appear in the Proceedings of the National Academy of Sciences.
Multiple sclerosis results from the progressive d... Read More
When cells are attacked by bacteria they use all means at their disposal to defend themselves. But cellular defence systems can damage the cells themselves and so need to be kept tightly in check. Recent results help us to understand how this is done and give pointers to new ways of combating di... Read More
Public health officials have been working for months to understand whether the XMRV virus poses a risk to the nation’s blood supply. The concern was sparked by a paper published last year in Science that detected the virus in the blood of 67% of chronic fatigue syndrome patients, compared to ju... Read More
Like a burglar with a universal lock pick, many deadly pathogens use the same protein to gain access to the cells of a potential host, researchers have discovered. The new findings could have implications for blocking infections by agents ranging from wheat rust to malaria.
Pathogenic fungi, ... Read More
In a laboratory where almost all the test tubes look green, the tools of modern biotechnology are being applied to lowly pond scum.
Foreign genes are being spliced into algae and native genes are being tweaked.
Different strains of algae are pitted against one another in survival-of-the-f... Read More
As if rows of serrated teeth and an uncanny ability to smell blood weren't deadly enough, sharks now have a new way to harm unsuspecting swimmers: drug-resistance bacteria.
According to recent research in the Journal of Zoo and Wildlife Medicine, sharks and redfish from shores off of Massachu... Read More
