Experimental antibiotic treats deadly MRSA infection

A new experimental antibiotic successfully treats the deadly MRSA infection and restores the efficacy of a commonly prescribed antibiotic that has become ineffective against MRSA. Scientists are racing to develop a new class of antibiotics to treat methicillin-resistant Staphylococcus aureus (MRSA) infections, which are responsible for 19,000 deaths annually and represent $3 billion in annual health care costs.
