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
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
Cigarettes host a bacterial bonanza of hundreds of different germs, including those responsible for many human illnesses, a new genetics study reports.
The data support findings described last September by scientists at the Roswell Park Cancer Institute in Buffalo, N.Y. They extracted tobacco... Read More
Gram-negative bacteria are practically built to withstand drugs, which is one reason few drug makers have rushed to pursue treatments.
The bacteria have a double cell membrane to shield them, compared with Gram-positive organisms, which have a single membrane. They can make various enzymes t... Read More
It sits smack in the centre of downtown Winnipeg and contains some of the world's deadliest pathogens behind air-tight walls and biosafety cabinets.
But new documents reveal Canada's National Microbiology Lab isn't immune to leaks, spills and failures in restricted areas where lethal organism... Read More
A promising new way to prevent the spread of HIV is being tested in Botswana on a group of people who are being exposed to a particularly vicious strain of the virus. They are now being treated with strong antiretroviral drugs.
The “test and treat’’ approach is not primarily intended to ward ... Read More
Development-stage drug developer Anadys Pharmaceuticals Inc. said late Wednesday its developing hepatitis C drug was only slightly more effective at treating the virus than placebo in a midstage study.
The company's shares plunged 46 cents, or 20 percent, to $1.85 in premarket trading.
Aft... Read More
With the World Health Organization warning yet again this week that the H1N1 virus has yet to reach its peak, a flu season that's milder than average hardly seems that way. Now, the nearly yearlong coverage of H1N1 has left some worried that future influenza outbreaks will be met with ambivalent... Read More
The suggestion that the retrovirus XMRV is the etiologic agent of chronic fatigue syndrome (CFS) arose from a study in which the virus was found in 68 of 101 US patients. The virus was not detected in two independent studies of 186 and 170 CFS patients in the United Kingdom. A new Dutch study ha... Read More
Contrary to popular belief, some disease causing bacteria may actually survive the composting process. Researchers from Agriculture and Agri-Food Canada report in the February 2010 issue of the journal Applied and Environmental Microbiology that campylobacter bacteria in cattle manure can surviv...
