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.

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
This video shows the process of injecting a a construct with gene manipulated DNA into a C. elegans worm. The outcome in this case was the rolling worm with the green fluorescent protein in it that localized to the body wall muscle, giving the worm the four green stripes along his body. 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...

Alex Fiorentino describes how the Whitesides lab at Harvard is developing sophisticated medical diagnostic devices that are lightweight, disposable, cost pennies to make, and operate without power. They're made out of paper. Read More
Top meat industry groups held briefings on Capitol Hill Tuesday defending the use of antibiotics as a critical tool for animal health.
The briefings come two weeks after CBS Evening News with Katie Couric broadcast a two-part series criticizing the widespread use of antibiotics in food animal... Read More
A micro-ear could soon help scientists eavesdrop on tiny events just like microscopes make them visible.
Initially, researchers will use it to snoop on cells as they go about their daily business. It may allow researchers to listen to how a drug disrupts micro-organisms, in the same way as a ... Read More
Here's an idea: Rehabilitate the tobacco plant by using it to make flu vaccine. (This may sound like a double-whammy nightmare for anyone who believes that vaccines are killing us all and GMOs are killing us all, but let's put that aside and examine what the scientists are doing, and why.)
Fi... Read More
Marine scientists long believed that a microbe called Trichodesmium, a member of a group called the cyanobacteria, reigned over the ocean's nitrogen budget.
New research results reported online February 25 in a paper in Science Express show that Trichodesmium may have to share its nitrogen-f... Read More
Snippets of RNA that switch off disease-causing genes can now slip into cells unaided. This could help efforts to use RNA interference (RNAi) to treat diseases such as cancer and diabetes.
For a gene to be expressed as a protein, it must first be copied into messenger RNA (mRNA). RNAi blocks ... Read More
A recent article published in the Columbia Journalism Review mulls over the state of science journalism and expresses hope that the future is online. The article actually singles out the MicrobeWorld-related blog Small Things Considered by Elio Schaechter and Merry Youle among several others as ... Read More

Stories of environmental damage and their consequences always seem to take place far away and in another country, usually a tropical one with lush rainforests and poison dart frogs.
In fact, similar stories starring familiar animals are unfolding all the time in our own backyards — including ... Read More
Mobile health or mHealth is part of a movement towards citizen-centered health services delivered through cellular technologies. Mobile phones in particular are becoming a first line of defense against emerging infectious diseases by keeping healthcare practitioners and the public informed ab... Read More
We've all experienced it. You take a lid off a bowl in the refrigerator and find those leftovers you had planned to eat covered in a disgusting white fuzzy substance. Or you reach for a slice of bread and see it has turned green.
University of Nebraska-Lincoln researchers are working to find ... Read More
