Researchers downplay MRSA screening as effective infection control intervention
Three Virginia Commonwealth University epidemiologists are downplaying the value of mandatory universal nasal screening of patients for MRSA, arguing that proven, hospital-wide infection control practices can prevent more of the potentially fatal infections. view more (2008-10-23)
C. difficile spores spread superbug
New research suggests that antibiotic treatment could be asymptomatically inducing the transmission of the healthcare-acquired infection, C. difficile, contributing to the outbreaks that have recently been widely reported in hospitals and other settings. view more (2009-07-21)
Scientists find mutations that let bird flu adapt to humans
By comparing influenza viruses found in birds with those of the avian virus that have also infected human hosts, researchers have identified key genetic changes required for pandemic strains of bird flu. view more (2006-11-16)
Researchers discover primer to plant defense system
By identifying a novel compound that primes a plant's immune system, researchers at Oak Ridge National Laboratory and the University of Chicago may be on a path to developing disease-resistant plants. view more (2009-04-06)
Auto immune response creates barrier to fertility; could be a step in speciation
Plant biologists at the Max Planck Institute of Developmental Biology and the University of North Carolina at Chapel Hill have discovered that an autoimmune response, triggered by a small number of genes, can be a barrier to producing a viable offspring. view more (2007-09-04)
Invertebrate immune systems are anything but simple, conference finds
A hundred years since Russian microbiologist Elie Metschnikow first discovered the invertebrate immune system, scientists are only just beginning to understand its complexity. view more (2007-06-21)
Researchers use mass spectrometry to detect norovirus particles
Scientists have used mass spectrometry for decades to determine the chemical composition of samples but rarely has it been used to identify viruses, and never in complex environmental samples. view more (2006-04-07)
Defining gene's role may lead to prevention of dangerous corn toxin
Discovery that a specific gene is integral to both fungal invasion of corn and development of a potentially deadly toxin in the kernels may lead to ways to control the pathogen and the poison. view more (2008-03-26)
First analysis of recent disease outbreak in China
Last year, there was major press coverage of an alarmingly large and deadly outbreak of Streptococcus suis disease in Sichuan province in China. view more (2006-04-11)
Scientists identify specific enzymes that make meningitis hard to fight
Two enzymes in meningitis bacteria which prevent the body from successfully fighting off the disease, and make the infection extremely virulent, have been identified in new research published today. view more (2007-02-23)
IL-21 receptor plays an essential role in the Th2 immune response
During the immune response cells known as Th2 cells express a variety of cytokines (e.g. interleukin-4, -5, and -13), many of which stimulate B cells to proliferate and produce antibodies. view more (2006-06-16)
Immunologists identify biochemical signals that help immune cells remember how to fight infection
Immunology researchers at UT Southwestern Medical Center have discovered how two biochemical signals play unique roles in promoting the development of a group of immune cells employed as tactical assassins. view more (2009-05-29)
Study Sheds New Light on Causes of Common Sexually Transmitted Diseases
Oral sex may be a risk factor for nongonococcal urethritis (NGU), one of the most common sexually transmitted diseases affecting both men and women. view more (2006-01-04)
LIAI Researchers Discover New Cellular Mechanism That Will Significantly Advance Vaccine Development
La Jolla Institute for Allergy & Immunology (LIAI) scientists have discovered one for the textbooks. Their finding, reported Friday in the scientific journal Immunity, illuminates a new, previously unknown mechanism in how the body fights a virus. view more (2008-06-17)
Researchers at Case Western Reserve discover a new way the body fights fungal infection
A team of researchers led by Amy G. Hise, M.D., M.P.H., assistant professor at the Center for Global Health and Diseases, Case Western Reserve University School of Medicine, is the first to discover how the body fights off oral yeast infections caused by the most common human fungal pathogen, Candida. view more (2009-06-12)
White blood cells are picky about sugar
Biology textbooks are blunt-neutrophils are mindless killers. These white blood cells patrol the body and guard against infection by bacteria and fungi, identifying and destroying any invaders that cross their path. view more (2007-07-12)
Tuberculosis: The bacillus takes refuge in adipose cells
A team from the Institut Pasteur has recently shown that the tuberculosis bacillus hides from the immune system in its host's fat cells. view more (2006-12-21)
Humans fostering forest-destroying disease
Enjoying your August vacation? Well, (as they say in the summer movies) there's a killer in the woods. Its strike has been consistently quiet, sudden, and deadly. view more (2007-08-16)
What's Killing the Coral Reefs?
The answer to what's killing the world's coral reefs may be found in a tiny chip that fits in the palm of your hand. view more (2009-02-05)
New insights could lead to a better pneumococcal vaccine
Discovery of a new, previously unknown mechanism of immunity suggests that there may be a better way to protect vulnerable children and adults against Streptococcus pneumoniae (pneumococcal) infection, say researchers at Children's Hospital Boston and Harvard School of Public Health (HSPH). view more (2008-09-23)
