Scientists in the US have developed a microdevice that investigates how bacteria communicate with each other to enhance their resistance to drugs.
Bacteria communicate in a process called quorum sensing, in which they secrete small signalling molecules called autoinducers. When bacteria pr... Read More

Women older than 40 are unlikely to get much benefit from the vaccine for the virus that causes cervical cancer, a new study reports.
The vaccine for human papillomavirus, or HPV, is recommended for women up to age 26 and girls as young as 9. To determine whether older women might be protect... Read More

With help from scientists from Stanford University’s medical school, North Korea has developed its first laboratory capable of detecting drug-resistant tuberculosis, scientists involved in the project said last week.
Tuberculosis surged in the Democratic People’s Republic of Korea during the... Read More
Numerous studies have debunked the theory that childhood vaccines cause autism, and autism researchers are now, for the most part, focusing on other potential causes of the disorder. But one in five parents still believe that vaccines may cause autism, according to a study released online Sunday... Read More
In an ideal world, we would have time to read every great paper coming out in all the microbiology journals each month. Instead we have to focus our reading on the topics that directly impact our research. But reading papers from other fields can often help us to find new methods or generate id... Read More
The Virginia Department of Game and Inland Fisheries (VDGIF) has received laboratory results from all chronic wasting disease (CWD) samples collected through the 2009-2010 hunting season, and no additional positives were found. Since 2002, nearly 5,000 samples have been collected in Virginia, an... Read More
A minor-league pitcher in his younger days, Richard Armbruster kept playing baseball recreationally into his 70s, until his right hip started bothering him. Last February he went to a St. Louis hospital for what was to be a routine hip replacement.
By late March, Mr. Armbruster, then 78, was ... Read More
The H1N1 virus's rapid spread worldwide last year exposed the weaknesses in the global system for swiftly developing, manufacturing and distributing vaccines for newly identified strains of influenza. In Texas, researchers are attacking the first two of these problems through Project GreenVax, ... Read More
Recently in the news, there was a noted “rash” of toilet seat rashes caused from contact with harsh cleaning chemicals that rubbed against the bottoms and thighs of toddlers. While these skin eruptions were caused by direct irritation, it reminds me of why so many women, including myself, never ... Read More
Microbes similar to those on Earth would have a tough time surviving the harsh environment of Mars, but it is not inconceivable that they could persist there given a little protection, according to a new study. The finding supports similar, previous work and lends credence to the theory that if ... Read More
Studying cholera just got a little easier, thanks to a new (old) animal model. For years, cholera research has relied on some less than ideal animal models: infant mice, which don't develop the diarrhea characteristic of severe cholera infection, and infant rabbits, which require surgery to inf...

A novel compound is highly effective against the pathogenic H5N1 avian influenza virus, including some drug-resistant strains, according to new research led by a University of Wisconsin-Madison virologist.
The work, published in the Public Library of Science journal PLoS Pathogens on Feb. 26,... Read More
Move over MRSA; a new battery of Gram-negative bacteria are quietly carving out big names for themselves, killing thousands of hospital patients each year as doctors look on with few effective tools to fight them. What’s worse, though these resistant strains are spreading, there are no effectiv... Read More
We all are very familiar with the effects of cannabinoid receptor stimulation on the body. Relaxation, pain relief, and increased appetite probably come first to mind. These psychoactive effects result from activation of the CB1 receptor found on cells in the brain by tetrahydrocannabinol (THC)... Read More
In Ireland, bacterial contamination of water is a national concern, with the Environmental Protection Agency reporting that over 25% of groundwater samples were contaminated with E. coli in the 2004 to 2006 period. E. coli is the most important indicator used in Ireland and its presence indicate... Read More
With their best chemical antibiotics slowly failing, scientists are increasingly looking to nature for a way to control deadly staph bacteria -- the culprit behind most hospital infections. Naturally toxic for bacteria, enzymes called lysins have the promising ability to obliterate staph, but th... Read More
