Viruses can be thought of as hyperspeed shape-shifters, organisms that can adapt quickly to overcome barriers to infection. But recent research has been finding ancient traces of many viruses in animal genomes, DNA insertions that have likely been there for much longer than the viruses were pre... Read More
Patients with suppressed immune systems can quickly develop H1N1 flu infections that resist all known drugs, doctors in the Netherlands reported on Wednesday.
The case of a 5-year-old leukemia patient who died from swine flu after the virus mutated in his body showed that people with weakened... Read More
An Iowa State University researcher searched for new genes that are turned on during infection in a type of mosquito that is not only a pest, but transmits disease-causing pathogens.
Lyric Bartholomay, assistant professor of entomology, along with colleagues from around the world, infected th... Read More
Researchers are inching their way toward a new HIV vaccine strategy by studying the cells of people who have naturally—and bafflingly—strong immune defenses against the virus.
Last year, Howard Hughes Medical Institute investigator Michel C. Nussenzweig's team figured out how to isolate key ... Read More
A chemical compound made from a type of bacteria discovered in the Florida Keys by a University of Florida pharmacy researcher has shown effectiveness in fighting colon cancer in preclinical experiments.
Writing online in the Journal of Pharmacology and Experimental Therapeutics, scientists ... Read More
The military has been a leader in recognizing and protecting against the spread of multidrug-resistant organisms, commonly known as “superbugs,” defense officials told Congress members yesterday.
"DOD has been actively engaged in measures to screen, surveil, prevent and control infection in m... Read More
America's hospitals are places of healing and hope. But they're also home to a growing threat. You may have heard of MSRA - a dangerous infection that can often be treated with antibiotics. Now there's a new class of superbugs - infections striking patients with little or no effective treatment ... Read More
Many virological techniques are based on the specificity of the antibody-antigen reaction. Examples in our virology toolbox include western blot analysis and ELISA. While very useful, these methods cannot be used to visualize viral proteins in infected cells or tissues. To do that we must turn t... Read More
The United States apologized on Friday for an experiment conducted in the 1940s in which U.S. government researchers deliberately infected Guatemalan prison inmates, women and mental patients with syphilis.
In the experiment, aimed at testing the then-new drug penicillin, inmates were infecte... Read More
An experimental vaccine designed to block genital transmission of herpes viruses from men to women has failed a major clinical trial aimed at obtaining manufacturing approval, researchers said Thursday. Because of the failure, the vaccine's manufacturer, GlaxoSmithKline, said it will abandon any... Read More
Bacteria have a way of sticking together. Lynette Cegelski, a Stanford assistant professor of chemistry, wants to unwind the secrets of exactly how they do it, the better to combat bacterial diseases.
Her research efforts just got a big boost – $1.5 million worth. She is one of three Stanford... Read More
New findings by National Institutes of Health scientists could explain how Salmonella bacteria, a common cause of food poisoning, efficiently spread in people. In a study published this week in the Proceedings of the National Academy of Sciences, researchers describe finding a reservoir of rapid... Read More

Billions of bacteria are hard at work helping "densify" oilsands tailings ponds at mine sites near Fort McMurray, a crucial step in the difficult and lengthy process of separating water from fine particles.
The trouble is many of these bacteria also generate methane, a greenhouse gas associat... Read More
Kathleen Alexander, associate professor of wildlife in Virginia Tech's College of Natural Resources and Environment, has discovered a novel tuberculosis (TB) species in the Mycobacterium tuberculosis complex, a group of pathogens that have adapted by using mammals as hosts. It has been nearly tw... Read More
