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
A non-pathogenic bacterium is capable to trigger an autoimmune disease similar to the multiple sclerosis in the mouse, the model animal which helps to explain how human diseases work. This is what a group of researchers from the Catholic University of Rome, led by Francesco Ria (Institute of Gen... Read More
A new international study reported in PLoS Medicine confirms that a single dose of nevirapine (sdNVP) can lead to HIV treatment failure in women who receive the drug to prevent transmission of the AIDS virus to their infants. However, the increased risk of failure could only be detected in women... Read More
Digger wasps of the genus Philanthus, so-called beewolves, house beneficial bacteria on their cocoons that guarantee protection against harmful microorganisms.
Scientists of the Max Planck Institute for Chemical Ecology in Jena teamed up with researchers at the University of Regensburg and th... Read More
I wonder whether we have entered a new chapter in the book of human knowledge sharing. I'm often working physically when I listen to my favorite science podcasters (TWIV, TWIP and Mark Crislip).... so your entertaining program is intertwined with raking leaves,... Read More
On episode #71 of the podcast This Week in Virology, Vincent, Dickson, Alan and Rich answer listener questions about maternal infection and fetal injury, viral gene therapy, eyeglasses and influenza... Read More
Maryland-based Virxsys Corp said tests on monkeys showed its HIV-based vaccine might at least treat infections, if not prevent them, and it is now seeking permission to try it in people.
And the privately held company is encouraged by some early results of a gene therapy approach to controlli... Read More
Just how dangerous influenza viruses can be has been shown by a research project which involved the mixing of very dangerous bird influenza viruses with ordinary more contagious influenza viruses. The researchers led by Professor Yoshihiro Kawaoka from the University of Wisconsin-Madison mixed u... Read More
True, the most highly publicized outbreaks of norovirus do seem to occur on cruise ships, and only in part because the idea of fun-loving tourists (i.e. vacationers) getting sick elicits a perverse pleasure in everyone else (i.e. non-vacationers). But lack of a desire to chug through pristine oc... Read More
Global supply of Atlantic salmon will decline the most in two decades this year after a virus decimated output in Chile, bolstering the steepest advance in Norwegian prices since at least 2000.
The harvest will drop 5 percent to 9 percent, the first “significant” decline since 1990, said Joer... Read More
This article is the first in a series that discusses the issue surrounding the molecular studies of soil microbiology. In this first article we cover the basics of soil and why it is one of the most challenging samples to study and how to overcome those challenges. There are major differences im... Read More
