An undiagnosed genetic disease appears to have been the critical factor in the 2009 death of a University of Chicago researcher from plague, investigators have concluded.
The 60-year-old man, Malcolm Casadaban, PhD, had been working with an attenuated strain of Yersinia pestis, the plague bac... Read More
New findings by a University of Maryland-led team of scientists indicate that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be a highly effective, specific and environmentally friendly tool for combating malaria, at a ti...

It's not just carbon dioxide that feeds a forest. Trees also depend on nitrogen to grow. And the best buffet of nitrogen comes from moss-loving bacteria. But to get a really nutritious growth of bacteria going, the moss needs to age.
Bacteria, called cyanobacteria, that grow on centuries-old ... Read More
The Centers for Disease Control and Prevention is reminding laboratory workers to be diligent about wearing protective gear, after it found that an Illinois researcher died in 2009 from exposure to plague-causing bacteria.
The 60-year-old researcher, a university employee, had been working wi... Read More
A research team led by Edward Yu of Iowa State University and the Ames Laboratory has identified and described two parts of the three-part system that pumps toxins from bacteria and allows them to resist antibiotics. The discoveries are published in the Feb. 24 issue of the journal Nature.

New research lends support to the idea that exposure to a wide range of microbes explains why farm kids have lower asthma rates than city kids.
School-aged children in the studies who lived on farms were about 30% to 50% less likely to have asthma than non-farm children who lived nearby.

Here's a not-so-savory news flash: There are more bacterial cells living in our bodies than human cells. Researchers are learning how the balance of these bugs affects our health, but reaping the benefits of bacteria is not quite as simple as eating probiotic yogurt. That's the gist of "The Good...

The bacterium, called Pseudomonas aeruginosa, is the most common cause of persistent and fatal lung infections in cystic fibrosis patients. Scientists at Liverpool identified a particularly virulent strain of the bacteria that is transmissible between patients. The Liverpool Epidemic Strain (LES... Read More
Childhood inoculations protect us against deadly infectious diseases like measles, whooping cough and polio. But they are also the source of near constant conflict — most recently in the Feb. 22 Supreme Court decision which ruled in favor of a vaccine manufacturer over the family of a disabled g...

The population and diversity of nitrogen-fixing bacteria in agricultural soils varies more according to what crop was previously farmed than with whether those soils are organically or conventionally farmed, according to a paper in the February 2011 issue of the journal Applied and Environmental...

Engineers at the Massachusetts Institute of Technology have designed a new type of nanoparticle, one that soon help deliver vaccines for infections such as malaria and HIV.
The particles (in red) consist of concentric fatty spheres capable of carrying synthetic versions of vaccine proteins. T... Read More
Many of the substances in our most common medicines are manufactured in India. Some of these factories release huge quantities of drugs to the environment. Swedish scientists now show that bacteria in polluted rivers become resistant to a range of antibiotics. International experts fear that thi... Read More
When a mysterious infectious disease breaks out, microbiologists at the Centers for Disease Control and Prevention need a fast, reliable way to identify and characterize the culprit. Now, researchers there and at the Georgia Institute of Technology have developed a new method for speedy identifi... Read More
Water filters on the market today can’t always stop bacteria from passing through. The problem is a structural one. It’s hard to get the pore sizes to align properly, leaving room for the pathogens to slip right on through.
But researchers at the University at Buffalo have developed a method ... Read More
A four-drug regimen over 10 days worked as well as the three-drug, seven-day regimen that's the standard ulcer treatment and may help overcome the growing problem of antibiotic resistance, researchers reported.
In a randomized, open-label phase III trial of 440 patients, the four-drug combo -... Read More
One bad apple is all it takes to spoil the barrel. And one misfolded protein may be all that's necessary to corrupt other proteins, forming large aggregations linked to several incurable neurodegenerative diseases such as Huntington's, Parkinson's and Alzheimer's.
