Bug-fighting stitches fight MRSA

The spread of super bug MRSA in operating theatres could be combated with the use of new stitches and dressings containing bacteria-fighting viruses, scientists have said.Infection-fighting agents can be bonded to materials such as nylon, according to researchers in Glasgow.These work by growing inside the bug-causing bacteria before bursting out to attacks others.Sutures - the hospital thread used to stitch up patients in operations - could host the viruses, reducing the chance of patients developing an infection.And dressings impregnated with the agents would prevent the spread of bacteria.Tests showed that the devices kill 96% of MRSA strains from patients in three different hospitals.Janice Spencer, from the University of Strathclyde, said: "Some bacteria specific viruses - called bacteriophages - have been used in the past to help clear up infections caused by bacteria, but their use died out when antibiotics like penicillin and methicillin became widely available."We are looking at them again now that multiple antibiotic resistant strains of bacteria have become such a problem in hospitals."The scientists have also developed a device to rapidly detects MRSA on surfaces.Using this, hospital staff could screen patients before surgery to limit the chances of them passing on an infection.Copyright � The Press Association 2008
