MRSA outbreak contained through DNA sequencing

The case has led to hopes the management of MRSA and other harmful bacterial infections could be vastly improved by the routine use of DNA sequencing technologies.

Researchers from the UK and USA initially performed whole-genome sequencing on MRSA isolates taken from 12 babies known to have been carrying MRSA during a six-month period in 2011.

Retrospective DNA sequencing on these isolates confirmed that the MRSA strains were closely related and part of an outbreak which had spread to the community.

The hospital infection control team also identified a new case of MRSA carriage in the special care baby
