A cluster of seven people infected with a Tamiflu-resistant strain of pandemic H1N1 influenza has been identified by researchers in Vietnam and reported in the New England Journal of Medicine.
The cases show the ability of Tamiflu-resistant pandemic H1N1 to spread among healthy people who are... Read More
What's gotten into you? In this hour we explore nature's moochers - the good, the bad, and the hideous. We have stories of lethargic farmers, zombie cockroaches, and even mind-controlled humans (kinda, maybe). Could parasites be the shadowy hands that pull the strings of life?

In fatal cases of 2009 H1N1 influenza, the virus can damage cells throughout the respiratory airway, much like the viruses that caused the 1918 and 1957 influenza pandemics, report researchers from the National Institutes of Health (NIH) and the New York City Office of Chief Medical Examiner.

Scientists studying how bacteria under stress collectively weigh and initiate different survival strategies say they have gained new insights into how humans make strategic decisions that affect their health, wealth and the fate of others in society.
Their study, published this week in the ea... Read More
Federal health officials said Thursday that almost 10,000 people had died of swine flu since April, a significant jump from mortality numbers released last month.
Officials also said that 50 million Americans, one sixth of the country, had caught the disease, and that 213,000 people had been ... Read More
On episode #62 of the podcast This Week in Virology, Vincent, Dickson, and Alan discuss STEP HIV-1 vaccine failure caused by the adenovirus vector, presence of West Nile virus in kidneys for years after initi... Read More
Infection with the H1N1 virus, or swine flu, causes more life-threatening complications than seasonal flu in children with sickle cell disease, according to research from Johns Hopkins Children’s Center. The findings, presented Dec. 7 at the annual meeting of the American Society of Hematology, ... Read More
Researchers from the UCLA AIDS Institute and colleagues have for the first time demonstrated that human blood stem cells can be engineered into cells that can target and kill HIV-infected cells — a process that potentially could be used against a range of chronic viral diseases.
The study, p... Read More
Greening, a devastating disease that threatens citrus crops worldwide, is almost certainly caused by one species of bacteria, not a combination of bacteria and viral pathogens.
That’s the conclusion reached by researchers at the University of Florida, who used genetic analysis to study the in... Read More
In a long-term study published in The Proceedings of the Royal Society B, U.S. researchers suggest that over-cleanliness could make babies more prone to inflammation later in life, and in turn raise the risk for stroke and heart disease.
Thomas McDade’s team studied more than 1,500 people in ... Read More
Global climate change has prompted efforts to drastically reduce emissions of carbon dioxide, a greenhouse gas produced by burning fossil fuels.
In a new approach, researchers from the UCLA Henry Samueli School of Engineering and Applied Science have genetically modified a cyanobacterium to c... Read More
A shortage of flu vaccines may soon become a problem of the past. Researcher Manon Cox has developed an alternative process for producing large quantities of safe and effective vaccines at twice to four times the usual speed. The process is based on using cells in bioreactors instead of fertilis... Read More
Helicobacter pylori infects up to 90 percent of people in the developing world and causes gastric ulcers and cancers of the gut. Now scientists have revealed a subterfuge used by the bacterium to trick stomach cells into playing along. By injecting a protein into the stomach lining that mimics a... Read More
Scientists have discovered a signaling pathway that tuberculosis bacteria use to coerce disease-fighting cells to switch allegiance and work on their behalf. Epithelial cells line the airways and other surfaces to protect and defend the body. Tuberculosis bacteria co-opt these epithelial cells i... Read More
The University of Pennsylvania and the University of Georgia have won a $14.6 million grant from the National Institute of Allergy and Infectious Diseases to expand a pathogen genomic database that serves as a resource for scientists studying infectious diseases, Penn said today.

Swine flu has sickened about 50 million Americans, and killed about 10,000, according to new estimates released by federal health officials on Thursday.
That means about 1 in 6 Americans have had the illness, said Dr. Thomas Frieden, director of the Centers for Disease Control and Prevention.... Read More
North Korea acknowledged nine cases of swine flu on Wednesday, but relief officials in South Korea reported that dozens of North Koreans had died of the flu.
North Korea’s official news agency, K.C.N.A., said the nine cases had been confirmed in the capital of Pyongyang and in Sinuiju, a town... Read More
The H1N1 influenza virus has been keeping a secret that may be the key to defeating it and other flu viruses as well.
Researchers at Rice University and Baylor College of Medicine (BCM) have found what they believe is a weakness in H1N1's method for evading detection by the immune system.
