High-throughput soil screening unearths strong antibiotic

An agent developed from soil-dwelling bacteria killed several strains of antibiotic-resistant bacteria and cleared cutaneous methicillin-resistant Staphylococcus aureus infections in rats in one day, researchers reported in Nature Microbiology. The scientists used a high-throughput method to screen bacteria DNA in 2,000 soil samples from across the US, and the method could be used to discover more antibiotic compounds.
