Researchers used advanced DNA sequencing technologies to confirm the presence of an ongoing outbreak of methicillin-resistant Staphylococcus aureus (MRSA) in a Special Care Baby Unit in real time. This assisted in stopping the outbreak earlier, saving possible harm to patients. This approach is much more accurate than current methods used to detect hospital outbreaks.Tue, 13 Nov 2012 21:46:46 ESThttp://www.sciencedaily.com/releases/2012/11/121113214635.htm
