The cause of exacerbations of a progressive and uniformly fatal lung disease remains a mystery.
But in most cases, acute worsening of idiopathic pulmonary fibrosis does not appear to result from a viral infection, according to Harold Collard, MD, of the University of California San Francisco,... Read More
Preliminary research suggests that statins restrain the immune systems of HIV patients and may stave off progression of the AIDS-causing virus.
Although it's too soon to recommend the drug for this purpose, the findings of this small study raise the possibility that "there might be drugs that... Read More
Most people would never suspect that a "trash tree," one with little economic value and often removed by farmers due to its ability to destroy farmland, could be the key to fighting a deadly bacterium. Now, a University of Missouri researcher has found an antibiotic in the Eastern Red Cedar tree... Read More
Their mothers had assured them they’d been vaccinated as children. Some even had the blood work to prove it. One woman had gotten a booster shot just a few years back, when she’d traveled abroad during college.

Cornell professor John March is attempting to transform bacteria in our gut into disease-fighting machines. Now, thanks to two members of his research team, he has a powerful new tool to help him do so: an artificial intestine.
The 3-D hydrogel scaffolds developed by graduate student Jiajie Y... Read More
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.
F... Read More
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... Read More
