Antibiotic-Resistant Bacteria Have Evolved a Unique Chemical Mechanism, New Discovery Reveals

Caption: Scientists have discovered a novel strategy by which antibiotic-resistant bacteria change their genetic make-up to evade multiple antibiotics. For the first time, scientists have been able to paint a detailed chemical picture of how a particular strain of bacteria has evolved to become resistant to antibiotics. The research is a key step toward designing compounds to prevent infections by recently evolved, drug-resistant "superbugs" that often are found in hospitals, as well as in the general population. A paper describing the research, by a team led by Squire Booker at Penn State University, will be posted by the journal Science on its early-online Science Express site on April 28, 2011.
