Antibiotics gain resistance, researchers fight back
U.S. News & World Report - 01/26/2015
Imagine a world where there is no cure for strep throat, pneumonia or a simple ear infection.
Today, most bacterial infections can be treated with a trip to the doctor and a quick round of antibiotics—but experts say this won’t be the case if bacteria continue to build resistance.
The majority of antibiotics come from soil microorganisms, but only about one percent of these microbes can be cultured in the lab, Kim Lewis, director of the Antimicrobial Discovery Center at Northeastern University in Boston, tells U.S. News. As a result, scientists have only had access to a small fraction of the bacteria that create antibiotics, making it difficult to develop enough new drugs as old ones become ineffective.
