FDA warning on oysters recently harvested from Mississippi area 2C

The U.S. Food and Drug Administration is advising retailers and food service operators not to offer for sale oysters harvested between Feb. 24 and March 17, 2009, from Mississippi Area 2C, located in the Mississippi Sound portion of the Gulf of Mexico near Pass Christian, Miss. Further, consumers are advised not to eat such oysters.

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.

Instant immunity through chemically programmable vaccination and covalent self-assembly

The experiments, thus far performed only in mice, appear to overcome a major drawback of vaccinations - the lag time of days, or even weeks, that it normally takes for immunity to build against a pathogen.

Epstein-Barr virus may be associated with progression of multiple sclerosis

Epstein-Barr virus (EBV), the pathogen that causes mononucleosis, appears to play a role in the neurodegeneration that occurs in persons with multiple sclerosis, researchers at the University at Buffalo and the University of Trieste, Italy, have shown.

Scientists manipulate bacteria into generating their own vaccine

Scientists have developed a way to manipulate bacteria so they will grow mutant sugar molecules on their cell surfaces that could be used against them as the key component in potent vaccines.

Meningitis bacteria dress up as human cells to evade our immune system

The way in which bacteria that cause bacterial meningitis mimic human cells to evade the body's innate immune system has been revealed by researchers at the University of Oxford and Imperial College London.

Statistical analysis could yield new drug target for multiple sclerosis

An elaborate statistical analysis of genes from more than 7,000 individuals has identified an amino acid that appears to be a major risk factor for multiple sclerosis, a devastating autoimmune disorder that afflicts 2.5 million people worldwide.

Long-sought protein structure may help reveal how ‘gene switch’ works

The bacterium behind one of mankind's deadliest scourges, tuberculosis, is helping researchers at the Commerce Department's National Institute of Standards and Technology (NIST) and the Department of Energy's Brookhaven National Laboratory (BNL) move closer to answering the decades-old question of what controls the switching on and off of genes that carry out all of life's functions.
