Scientists Look for Superbugs in ICU to Develop MRSA Sampling System
The term MRSA or methicillin resistant Staphylococcus aureus is used to describe those examples of the organism Staphylococcus aureus, that are resistant to commonly used antibiotics. Methicillin was an antibiotic used many years ago to treat patients with Staphylococcus aureus infections. It is now no longer used except as a means of identifying this particular type of antibiotic resistance.
"We are developing a standard sampling regime to take swabs from sinks, taps, floors and other surfaces like computer keyboards, and use these to identify accurately which superbug genes are present in an intensive care unit. Critically ill patients in the intensive care unit are particularly at risk from hospital acquired infections," said Gemma Kay from Sheffield Hallam University in South Yorkshire.
Along with the clinical collaborators at the Sheffield Teaching Hospitals Trust, the researchers are working to develop procedures for infection control, which could protect patients at risk and help to control any future superbug outbreaks.
"Our technique allows us to characterise the genes from micro-organisms using a gene amplification technique called polymerase chain reaction (PCR). This lets us expand tiny samples enough to identify individual strains of bacteria, and to spot particular antibiotic resistance genes," said Kay.
