Antibiotics 'may have given rise to MRSA bug'

Early use of antibiotics in the 1960s may have given birth to one of the most common strains of MRSA, a study has found.

A new genetic method of tracking infection suggests that the superbug emerged five decades ago in Europe, just as antibiotics were being widely introduced for the first time. Scientists used DNA-mapping technology to compare the genetic relatedness of bugs isolated from individual patients.

By identifying letter changes springing up in the bacteria's genetic code, they were able to track MRSA transmission between continents and from patient-to-patient within a single hospital.

The technique, pioneered by scientists at the Wellcome Trust Sanger Institute in Hinxton, Cambridgeshire, is expected to help improve infection control strategies aimed at keeping superbugs at bay.
