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
Tuesday's earthquake in Haiti left some 300,000 people homeless. Many are clustering in public places without food, clean water or sanitation. It's the perfect environment for the spread of communicable disease. VOA's Carol Pearson reports on health concerns Haitians face in the wake of Tuesday'... Read More
For those interested in sequencing and/or using microbial genomes, I am requesting input from the community on what you see as the benefits that can come from finishing microbial genomes as opposed to just doing the "shotgun" phase of sequencing (more detail is described on the blog post).

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
