Interesting multi-prong approach to killing bacteria - similar to that used in cancer treatment. Newly discovered chemical compounds can make MRSA bacteria vulnerable to the antibiotics they normally resist, restoring the old drug’s former powers.
This method of using existing antibiotics in combination with compounds that restore their potency could be a powerful weapon in the global antibiotic resistance crisis. A similar strategy is already used to treat Escherichia coli and pneumonia that have become resistant to beta-lactamase. These bacteria have an enzyme that breaks these antibiotics down, but adding compounds that inhibit this enzyme makes beta-lactams more effective."
