Bullfrogs could play a vital role in the fight against the MRSA superbug, research has revealed.
Researchers at St Andrews University in Scotland found that ranalexin, a protein secreted by Rana bullfrogs can be used to inhibit the infection.
Ranalexin was combined with another substance to achieve the positive results.
Dr Peter Coote, a microbiologist who led the study, said: "Our findings represent a potentially novel way to combat MRSA via surface treatment or impregnation of wound dressings.
"We have shown that this works in the lab, now we want to see if it would work in topical application, like around the surface of a catheter.
"If it works then it could be a very good way of preventing MRSA."
By combining the two substances, Dr Coote explained that the treatment was more difficult for MRSA to become resistant to it since it has to overcome two compounds rather than just one.
Around 30 per cent of people carry MRSA in their nose or on their skin.
It causes around 2,000 deaths each year in the UK and is responsible for many hospital infections.
