Researchers have used whole genome sequencing to reveal if drug-resistant bacteria are transmitted from animals to humans in two disease outbreaks that occurred on different farms in Denmark. The results, which are published today in EMBO Molecular Medicine, confirm animal-to-human transmission ... Read More
Shanghai Daily has a web page set up that shows the geographic distribution of H7N9 infections and fatalities in China. There is also a news feed, information on symptoms and a photo gallery. Click "source" to view. Read More
Beijing confirmed that a 7-year-old girl has H7N9 avian influenza and Henan province reported its first two cases, opening a new front in the spread of the virus in the world’s most populous nation. Shanghai said today two people infected with the strain of bird flu died, taking the country’s de... Read More
What is the influenza A(H7N9) virus?
Influenza A H7 viruses are a group of influenza viruses that normally circulate among birds. The influenza A(H7N9) virus is one subgroup among the larger group of H7 viruses. Although some H7 viruses (H7N2, H7N3 and H7N7) have occasionally been found to in... Read More
Bacteria that grows only on rocks in the Swiss Alps has helped researchers identify how alcohol might affect key brain proteins.
“Now that we’ve identified this key brain protein and understand its structure, it’s possible to imagine developing a drug that could block the binding site,” says ... Read More
The normally civil world of international health diplomacy was shattered yesterday, when Saudi Arabia complained that a patent taken out by Dutch scientists who isolated the Middle Eastern Respiratory Syndrome (MERS) virus was impeding Saudi efforts to track the virus within its own borders.

French scientist Francoise Barre-Sinoussi almost didn't get the chance to make one of the greatest medical discoveries of the 20th century.
She shared the 2008 Nobel Prize in Physiology or Medicine with her colleague Luc Montagnier for identifying HIV, the virus that causes AIDS, a plague tha... Read More
Observing microbes in nature is a challenge. Compared to what goes on in the lab, there is not much one can do with them out there. So, instead of bringing the bacteria to the lab, why not bring the lab to the bacteria? Imagine being able to capture the expression of genes of a community of micr... Read More
New research in The FASEB Journal suggests that a network of steroid molecules found in the brain is disrupted during HIV infection, and treatment with the steroid DHEA-S prevents brain damage.
A team of scientists from Canada, Thailand and Morocco have found that DHEA-S may prevent neurocogn... Read More
Patients in the UK have been enrolled into a trial to see if an engineered virus can be used to heal their damaged and struggling hearts. The trial will use a virus to introduce genetic material into heart muscle to reverse the organ's decline. The British Heart Foundation said the idea had "gre... Read More
One of the things that makes it extremely hard for life to flourish in foreboding places like Mars and the moons of Saturn is the punishing cold. Without the benefit of a blanket-like atmosphere, these celestial bodies have average temperatures well below freezing. Now, researchers from McGill U... Read More
Your body clock may play a role in fighting off bacterial infections in the gut, according to a new study in animals.
Researchers said the findings could help explain why people who have disruptions in their circadian rhythm -- like those who fly across time zones frequently, or shift workers... Read More
When a phage invades a host’s premises, it delivers only its genome and perhaps a few specialized proteins needed immediately upon arrival. Its plan is simply to supervise production. The host is relied on to provide not only the raw materials and energy, but also the production equipment needed... Read More
LOS ALAMOS, N. M., March 29, 2013—A new study by Los Alamos National Laboratory and University of Pennsylvania scientists defines previously unknown properties of transmitted HIV-1, the virus that causes AIDS. The viruses that successfully pass from a chronically infected person to a new individ... Read More
A team of researchers based at Johns Hopkins has decoded a system that makes certain types of immune cells impervious to HIV infection. The system's two vital components are high levels of a molecule that becomes embedded in viral DNA like a code written in invisible ink, and an enzyme that, whe... Read More
Bacteria that glide together… make art together? This contender in the Art of Science competition run by Princeton University in New Jersey, entitled The history of gliding, depicts the squiggly gliding paths of the bacteria Myxococcus xanthus.
M. xanthus are social bacteria that move in coor... Read More
National Institutes of Health (NIH) researchers have developed a model of infection in rhesus macaques that will help scientists around the world better understand how an emerging coronavirus, first identified in September 2012, affects people. The virus has so far infected at least 17 people in... Read More
Women suffering from recurring urinary tract infections may carry a particularly hearty strain of E. coli bacteria that flourishes in both the gut and the bladder, and can migrate back and forth despite repeated treatments, a small new study finds.
Doctors believe that urinary tract infection... Read More
I had a conversation with some colleagues last week about “personalized medicine,” which has been transformed now into the term “precision medicine.” The conversation revolved around what to do about the perceived effects of antibiotic treatment on the microbiota of individuals. How does one tre... Read More
