Scientists use Nature against Nature to develop an antibiotic with reduced resistance

Scientists at Rockefeller University and Astex Pharmaceuticals have discovered a new broad range antibiotic that kills a wide range of bacteria, including drug-resistant Staphylococcus (MRSA) bacteria that do not respond to traditional drugs, in mice. The antibiotic, Epimerox, targets weaknesses in bacteria that have long been exploited by viruses that attack them, known as phage.

Anthrax bacteria conspire with viruses to stay alive

New research suggests that anthrax-causing bacteria work synergistically with viruses to extend each other’s life spans. The work puts scientists on a new playing field in the fight against biological warfare and antibiotic-resistance, and also calls into question the degree to which our genomes are the sole masters of our fates.

Newly discovered protein kills Anthrax bacteria by exploding their cell walls

A newly discovered protein called PlyPH specifically targets one of our most feared bioterror threats, the anthrax bacterium, by punching holes in its cell wall and exploding it. Scientists at Rockefeller say the protein has several advantages over antibiotic drugs — and a solution based on it could clean areas that have been contaminated with anthrax spores. More »

Natural-born killers enlisted to fight anthrax

Researchers at The Rockefeller University have hit upon a promising method for rapidly and effectively treating people infected with the deadly anthrax bacterium — including feared drug – resistant strains. The new research, reported in the August 22 issue of Nature, takes advantage of anthrax’s number one natural enemy: bateriophage, or “bacteria – eating” viruses. More »
