Researchers are finding out which bugs grow in intensive care units to develop a novel sampling regime that would indicate the threat of MRSA and other superbugs in the environment, scientists heard (Monday 31 March 2008) at the Society for General Microbiology's 162nd meeting being held this week at the Edinburgh International Conference Centre.
“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,” says Gemma Kay from Sheffield Hallam University in South Yorkshire. “Critically ill patients in the intensive care unit are particularly at risk from hospital acquired infections.”
The university research team has been working with clinical collaborators at the Sheffield Teaching Hospitals Trust to develop infection control procedures which could protect vulnerable patients and help to manage 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,” says Gemma Kay.
