Bullfrog could help superbug fight
Updated on 30 April 2007
American bullfrogs could hold the key to eliminating the MRSA superbug from hospital wards, scientists said.
Researchers at St Andrews University have developed a novel treatment which kills the infection.
One of its key ingredients is ranalexin, a protein secreted by the Rana species of bullfrogs.
When scientists combined it with the enzyme lysostaphin they found had a "potent and significant" inhibitory effect on MRSA.
Microbiologist Dr Peter Coote, who led the study, said: "Our finding represents a potentially novel way to combat MRSA via surface treatment or impregnation of wound dressings.
"Together the ranalexin and lysostaphin are very, very potent as any resistance has to overcome two hurdles.
"They kill the organism extremely quickly and effectively."
The 18-month study was funded by the Biotechnology and Biological Sciences Research Council (BBSRC).
Dr Coote's team have applied for a further grant which will allow them to continue their research.
They are also in touch with pharmaceutical companies to see if the treatment could be marketed commercially in the future.
