Hos­pi­tals in cities ‘breed MRSA’

The Peterborough Evening Telegraph - - Uk&world Update -

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.
