Hospitals in cities ‘breed MRSA’
HOSPITALS in large cities act as breeding grounds for the superbug MRSA before it spreads out across the country, a new study has revealed. Researchers have found evidence that variants of the potentially deadly infection found in smaller regional hospitals probably originated from larger city hospitals. The University of Edinburgh study looked at the genetic make-up of around 80 variants of a major clone of MRSA found in hospitals. Scientists were able to determine the genetic code of MRSA bacteria taken from infected patients. They then identified mutations in the bug, which led to the emergence of new MRSA variants and traced their spread around the UK.
