From New Scientist:
From superbug to… bug. Newly discovered chemical compounds can make MRSA bacteria vulnerable to the antibiotics they normally resist, restoring the old drug’s former powers.
Methicillin-resistant Staphylococcus aureaus, commonly known as MRSA, is a major cause of hospital-acquired infections, and the second biggest cause of death by drug-resistant bacteria in the US. These bacteria are resistant to the most widely used class of antibiotics, called beta-lactams, which include penicillin, methicillin and carbapenems.
