Mosquito immune system examined
Mosquitoes employ the same immune factors to fight off bacterial pathogens as they do to kill malaria-causing Plasmodium parasites, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health. view more (2006-06-09)
Antibody-based therapies effective at controlling malaria
Passive immunization through the development of fully human antibodies specific to Plasmodium falciparum may be effective at controlling the disease, report researchers led by Dr. Richard S. McIntosh from the University of Nottingham in a paper published this week in the open-access journal PLoS Pathogens. view more (2007-05-18)
'GreeneChip' — New diagnostic tool that rapidly and accurately identifies multiple pathogens
Researchers in the Greene Infectious Disease Laboratory at Columbia University Mailman School of Public Health and their colleagues in the WHO Global Laboratory Network have developed a new tool for pathogen surveillance and discovery-the GreeneChip System. view more (2006-12-06)
Malaria, potato famine pathogen share surprising trait
Two wildly different pathogens — one that infects vegetables, the other infecting humans—essentially use the same protein code to get their disease-causing proteins into the cells of their respective hosts. view more (2006-05-30)
New malaria agent found in chimpanzees close to that commonly observed in humans
Researchers based in Gabon and France report the discovery of a new malaria agent infecting chimpanzees in Central Africa. view more (2009-05-29)
Researchers discover ancient origins of tuberculosis-causing bacteria
Researchers have long considered tuberculosis, a bacterial respiratory disease that kills 3 million people each year, a relatively recent human affliction. view more (2005-08-19)
Ticks, flukes, and genomics: Emerging pathogens revealed
Ehrlichiosis is no star of science. This emerging disease has an awkward name, vague flu-like symptoms, and a nasty habit of being caused by bacteria that live inside ticks and flatworms. view more (2006-02-17)
Scientists determine structure of enzyme that disrupts bacterial virulence
A team of biomedical researchers from Brandeis University and the University of Texas at Austin has determined the first 3-dimensional structure of an enzyme that may be pivotal in preventing certain bacterial infections in plants, animals and humans. view more (2005-08-31)
Breaks in hibernation help fight bugs
A habit in some animals to periodically wake up while hibernating may be an evolutionary mechanism to fight bacterial infection, according to researchers at Penn State. view more (2006-08-17)
Extinctions linked to climate change
A new report that links global warming to the recent extinction of dozens of amphibian species in tropical America is more evidence of a large phenomena that may affect broad regions, many animal species and ultimately humans. view more (2006-01-12)
The dangerous legacy of lead
Although lead is a well-known human health hazard, researchers at the University of Rochester Medical Center have discovered a new aspect of how it may work in mice to harm the function of T-cells. view more (2005-11-16)
Ecology Drives The Worldwide Distribution Of Human Diseases
Mounting evidence suggests that ecological and climatic conditions influence the emergence, spread, and recurrence of infectious diseases. Global climate change is likely to aggravate climate-sensitive diseases in unpredictable ways. Increasingly, public health programs aimed at preventing and controlling disease outbreaks are considering aspects... view more... (2004-06-09)
Stealth technology maintains fitness after sex
Pathogens can become superbugs without their even knowing it, research published today in Science shows. 'Stealth' plasmids-circular 'DNA parasites' of bacteria that can carry antibiotic-resistance genes-produce a protein that increases the chances of survival and spread of the antibiotic-resistant strain. view more (2007-01-12)
UCSD team unmasks family of immune system invaders
Like a family of petty criminals gone wrong, researchers at the University of California, San Diego (UCSD) were surprised to find that bacterial pathogens found in a number of troublesome diseases are actually related. view more (2006-01-13)
UCR-led study identifies crucial mechanism involved in immune response against viruses
A research team led by UC Riverside scientists has shown that the common fruit fly can serve as an excellent model for studying the immunity animals are born with for fighting viral infections. view more (2006-03-24)
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)
Scientists find a key to immune system's ability to remember
Its ability to accurately catalog and recall long past encounters with viruses, bacteria and other pathogens is why we only get the measles or chicken pox once, and is why exposure to deactivated virus particles in vaccines confers protection from disease. view more (2006-10-24)
Small molecule inhibitor of cholera discovered
Just as hurricanes in the Gulf states and Guatemala have raised the risks of cholera outbreaks, researchers at Harvard Medical School have identified a new type of antibiotic against the cholera bacteria. view more (2005-10-17)
ETH Zurich: Fast and Cheap Detection of Bacteria
Carbohydrates displayed on the surface of cells play critical roles in cell-cell recognition, adhesion, signaling between cells, and as markers for disease progression. Neural cells for instance use carbohydrates to facilitate development and regeneration and viruses recognize carbohydrates to gain entry into host cells. Identification of the... view more...

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)
