Bad news for disease-causing bacteria!

Scientists have what could be some very bad news for disease-causing bacteria. All three major classes of antibiotics that kill infectious bacteria do so in part by ramping up the production of harmful free radicals, researchers report in the September 7, 2007, issue of Cell, a publication of Cell Press.

A chink in bacteria's armor

Biomedical researchers at Boston University's College of Engineering may have discovered the path toward developing better drugs capable of defeating so-called “superbugs,” bacteria that have developed resistance to common antibiotics. The researchers have discovered a previously unknown chain of events occurring in bacteria that opens to door to new avenues of research.
