New aging studies improving vaccine efficacy for the elderly
A new study from the Trudeau Institute in Saranac Lake, New York, demonstrates that immune system cells important for both pathogen resistance and vaccine efficacy live longer in older animals but because of this longevity acquire functional defects. view more (2009-10-06)
Plague agent helps UT Southwestern researchers find novel signaling system in cells
The bacterium that causes bubonic plague would seem unlikely to help medical scientists, but researchers at UT Southwestern Medical Center have harnessed it to uncover a new regulatory mechanism that inhibits the immune system. view more (2006-05-26)
Stopping germs from ganging up on humans
Keeping germs from cooperating can delay the evolution of drug resistance more effectively than killing germs one by one with traditional drugs such as antibiotics, according to new research from The University of Arizona in Tucson. view more (2008-11-20)
AIDS Drug from Sunflowers
Sunflowers can produce a substance which prevents the AIDS pathogen HIV from reproducing, at least in cell cultures. view more (2006-01-09)
Fungus genome yielding answers to protect grains, people and animals
Why a pathogen is a pathogen may be answered as scientists study the recently mapped genetic makeup of a fungus that spawns the worst cereal grains disease known and also can produce toxins potentially fatal to people and livestock. view more (2007-10-08)
Pathogen that causes disease in cattle also associated with Crohn's disease
People with Crohn's disease (CD) are seven-fold more likely to have in their gut tissues the bacterium that causes a digestive-tract disease in cattle called Johne's disease. view more (2008-08-11)
Web model of influenza-host lifecycles will aid scientists in creating anti-viral drugs
A "starry sky" map linking the myriad interactions between the influenza virus and its human host will help guide researchers in creating new anti-viral drugs, say researchers at UT Southwestern Medical Center. view more (2006-01-31)
Combination of technologies works best against E. coli
No one weapon in the food-safety arsenal will take out E. coli 0157:H7, a nasty little pathogen that's becoming far too familiar to Americans, say University of Illinois scientists Scott Martin and Hao Feng. view more (2006-12-13)
Tearing down the fungal cell wall
Scientists at the Virginia Bioinformatics Institute and Duke University Medical Center have pinpointed a fungal gene that appears to play an important role in the development and virulence of Alternaria brassicicola. view more (2006-12-05)
Probiotic bacteria protect endangered frogs from lethal skin disease
Laboratory tests and field studies conducted by James Madison University (JMU) researchers continue to show promise that probiotic bacteria can be used to help amphibian populations, including the endangered yellow-legged frog, fend off lethal skin diseases. view more (2008-06-05)
Too Much of a Good Thing: Understanding Plants' Overactive Immune System Will Help MU Researchers Build Better Crops
A plant's immune system protects the plant from harmful pathogens. If the system overreacts to pathogens, it can stunt plant growth and reduce seed production. view more (2009-05-28)
First all-African produced genetically engineered maize is resistant to maize streak virus
Maize streak viruses (MSV), geminiviruses that can destroy most of a maize crop, are endemic to sub-Saharan Africa and adjacent Indian Ocean islands where they are transmitted by leafhoppers in the genus Cicadulina. view more (2007-07-09)
Genome info from 'plant destroyers' could save trees, beans and chocolate
An international team of scientists has published the first two genome sequences from a destructive group of plant pathogens called Phytophthora-a name that literally means "plant destroyer." view more (2006-09-05)
Knockouts in human cells point to pathogenic targets
Whitehead researchers have developed a new type of genetic screen for human cells to pinpoint specific genes and proteins used by pathogens, according to their paper in Science. view more (2009-11-30)
Environmental cleaning intervention reduces transmission of multidrug-resistant organisms in ICUs
A rigorous environmental cleaning intervention can reduce the transmission of methicillin-resistant Staphylococcus aureus (MRSA) and other multidrug-resistant organisms in hospital intensive care units (ICUs), according to a new study released today at the annual meeting of the Society for Healthcare Epidemiology of America (SHEA). view more (2009-03-20)
Scientists confirm new virus responsible for deaths of transplant recipients in Australia
In the first application of high throughput DNA sequencing technology to investigate an infectious disease outbreak, scientists from Columbia University Mailman School of Public Health, the Victorian Infectious Diseases Reference Laboratory (VIRDL) in Melbourne, Australia, the Centers for Disease Control and 454 Life Sciences link the discovery of... view more...

Foodborne pathogens hard to remove from produce, research is ongoing
Will you ever feel comfortable eating fresh spinach again? All raw agricultural products carry a minimal risk of contamination, said a University of Illinois scientist whose research focuses on keeping foodborne pathogens, including the strain of E. coli found recently on spinach, out of the food supply. view more (2006-10-03)
Jefferson scientists discover a key protein regulator of inflammation and cell death
Reporting in the journal Nature, researchers led by Emad Alnemri, Ph.D., professor of Biochemistry and Molecular Biology in the Kimmel Cancer Center at Jefferson, discovered a key protein component involved in inflammation. view more (2009-01-23)
Researchers map how staph infections alter immune system
Infectious disease specialists at UT Southwestern Medical Center have mapped the gene profiles of children with severe Staphylococcus aureus infections, providing crucial insight into how the human immune system is programmed to respond to this pathogen and opening new doors for improved therapeutic interventions. view more (2009-07-14)
