The bacteria responsible for most cases of food poisoning in the U.S. has been turned into an efficient biological factory to make chemicals, medicines and, now, fuels. Chemical engineer Jay Keasling of the University of California, Berkeley, and his colleagues have manipulated the genetic code ... Read More
Fragments of an abundant protein produced by the prostate form amyloid fibrils that enhance infection of cells by human immunodeficiency virus type 1. These fibrils, called semen-derived enhancer of virus infection (SEVI), have been found to boost infection of prostate cells by the retrovirus XM... Read More
Scientists have long pondered the seeming contradiction that taking broad-spectrum antibiotics over a long period of time can lead to severe secondary bacterial infections. Now researchers from the University of Pennsylvania School of Medicine may have figured out why.
The investigators show ... Read More
The American Society for Microbiology (ASM) will host its 2010 Biodefense and Emerging Diseases Research Meeting February 21-24, 2010 at the Baltimore Marriott Waterfront Hotel in Baltimore, MD.
The purpose of this meeting is to bring together individuals who are carrying out research to defe... Read More
A study aimed to measure rates of hand sanitizer use in a hospital entrance foyer four months after a baseline study during New Zealand's influenza pandemic found that of the 743 people observed over one (summer) day in December 2009, 8.2% used the hand sanitizer, which was significantly lower (...

New research at the A. James Clark School of Engineering could prevent bacterial infections using tiny biochemical machines – nanofactories – that can confuse bacteria and stop them from spreading, without the use of antibiotics.
...nanofactories can tell the difference between bad (pathogeni... Read More
For the past 50 years, scientists have scoured the skies for radio signals from beyond our planet, hoping for some sign of extraterrestrial life. But one physicist says there's no reason alien life couldn't already be lurking among us — or maybe even in us.
Paul Davies, an award-winning Arizo... Read More
For years, scientists have attempted to construct new bacterial genomes from scratch, in the hope of genetically engineering a microbe that produces biofuels or drugs. Turns out, they've been doing it the hard way. A new study finds that editing existing genomes down to only the desired genes w... Read More
The movie "Extraordinary Measures," now in wide release, tells the true story of John and Aileen Crowley, whose two youngest children were diagnosed with Pompe disease. The disease, a form of muscular dystrophy, causes severe muscle weakness and difficulty breathing. John Crowley quit his job an... Read More
Fast-spreading parasite species force sex changes on their victims, induce virgin births, and turn animals into "gross monsters"—among other horrors.
Now a new study has decoded how the bacteria may be able to wreak their havoc: by shutting down immune systems.
The parasites, of the Wolbac... Read More
Two weeks after a massive earthquake leveled much of this impoverished city, a wave of new infections and injuries has emerged, further taxing the nation’s shattered health care system.
Patients whose wounds were treated in the chaotic days following the quake are now returning with deep infe... Read More
We've long been warned of swine flu's split personality: mild in most cases, but severe in a few. Now the figures are bearing this out.
The US Centers for Disease Control and Prevention reports that 282 people under 18 died in the H1N1 flu pandemic in the US, between its start in April 2009 a... Read More
Today is apparently Dropped Food Day, with two articles coming out about dropped food safety and ethics. This entry from the LA Times has a pretty funny flow chart for making a decision on whether to eat a dropped piece of food and it references a recent study into the actual biology of the 5-se...

The kind of worm and protozoan infections that are often called neglected “tropical” diseases are also common among aboriginal peoples living in the Arctic, according to a recent survey.
Outbreaks of trichinosis, a larval-worm disease commonly associated with eating undercooked pork and carn... Read More
Mankind may finally have a weapon to fight two of the world's deadliest diseases.
A University of Central Florida biomedical researcher has developed what promises to be the first low-cost dual vaccine against malaria and cholera.
There is no FDA approved vaccine to prevent malaria, a mosq... Read More
(Excerpted from MomLogic.com, a discussion site on parenting. The comments below the story provide an interesting insight into people's reaction to Dr. Tierno's advice)
Momlogic's Vivian: My kids have done it. Your kids have done it. A chocolate chip cookie or some other irresistible morsel o... Read More
The hunt for the genetic roots of common diseases has hit a blank wall.
The genetic variants found so far account in most cases for a small fraction of the genetic risk of the major killers. So where is the missing heritability and why has it not showed up?
A Duke geneticist now suggests ... Read More
A viral infection is like an uninvited, tenacious houseguest in the cell, using a range of tricks to prevent its eviction. Researchers at the Salk Institute for Biological Studies have identified one of the key proteins allowing herpes simplex virus (HSV) DNA to fly under the radar of their host... Read More
Poster's note - with one of my favorite foods being recalled due to salmonella contamination (http://www.microbeworld.org/index.php?option=com_jlibrary&view=article&id=2567)) , this study is of great importance:
In developed countries, nontyphoidal Salmonella (NTS) strains are mainly food-bor... Read More
