Blasting drug-resistant superbugs with alternating treatments of multiple antibiotics could prove key in keeping the infections at bay, research has suggested.
Scientists found that flipping between two antibiotics helped beat bacteria, even when it had already developed some resistance genes.
The same effect was not seen when much higher doses of single antibiotics, or a mixture of the two, were administered.
The research was carried out by a team from the University of Exeter, and published in the online journal Public Library of Science Biology.
Scientists say it could breathe new life into the antibiotic discovery industry, which has struggled in recent years to keep up with the rise of MRSA and other superbugs.
