Mere Visual Perception of Other People’s Disease Symptoms Facilitates a More Aggressive Immune Response


An experiment (N = 28) tested the hypothesis that the mere visual perception of disease-connoting cues promotes a more aggressive immune response. Participants were exposed either to photographs depicting symptoms of infectious disease or to photographs depicting guns. After incubati... Read More

Major Funding To Study Prevention Of Drug-Resistant Staph Infections

A UC Irvine infectious disease specialist has received a three-year, $10 million grant to explore the effectiveness of new methods to prevent staph infections in people who harbor MRSA bacteria when they're discharged from the hospital.

Identification Of A New Bacterial Foe In Cystic Fibrosis

Exacerbations in cystic fibrosis (CF) may be linked to chronic infection with a bacterium called Stenotrophomonas maltophilia, which was previously thought to simply colonize the CF lung. The finding that chronic infection with S. maltophilia is independently linked with an increased risk of ex... Read More

Potent cancer fighter lies in Keys algae beds

Researchers working to conquer one of the nation's deadliest cancers think they may have found a silver bullet in what might seem a most unlikely place: the blue-green algae beds of Pickles Reef, off the coast of Key Largo.

Meanwhile, an Islamorada inhabitant, the bright orange, two-inch-long... Read More

Ancient "Fossil" Virus Shows Infection to Be Millions of Years Old

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

H1N1 flu virus can mutate in immunosuppressed patients: study

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

Mosquito Gene Examined for New Disease Response

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.

Antibodies with More “Hang Time” May Give Researchers a Jump on New HIV Vaccine Strategy

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

Alarming Uptick of Deadly Superbugs in Hospitals

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

Detecting viral proteins in infected cells or tissues by immunostaining

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

U.S. apologizes for syphilis experiment in Guatemala
