Researchers have developed a technique for precisely tracking the spread of the superbug MRSA in hospitals.
The team from the Wellcome Trust Sanger Institute in Cambridge looked at the genomes of MRSA strains from across the globe and at one hospital in Thailand.
They were able to spot small changes that allowed them to track the strain back to an individual patient.
They say this adds to the understanding of how MRSA can spread so rapidly and should lead to better treatments.
DNA sequencing
The research, which is published in the journal Science, involved teams in the UK, in Bath, Oxford and London, and Thailand, Portugal and the United States.
Scientists used new high-throughput DNA sequencing technologies to compare MRSA samples from patients to show how they were genetically related. - BBC
