New antibiotic family discovered in dirt US scientists have discovered a new family of antibiotics in soil samples.
The natural compounds could be used to combat hard-to-treat infections, the team at Rockefeller University hopes.
Tests show the compounds, called malacidins, annihilate several bacterial diseases that have become resistant to most existing antibiotics, including the superbug MRSA.
Experts say the work, published in Nature Microbiology, offers fresh hope in the antibiotics arms race.
Drug-resistant diseases are one of the biggest threats to global health.
They kill around 700,000 people a year, and new treatments are urgently needed. BBC News
