A peptide found in bullfrogs, called ranalexin, may help control MRSA, claim St Andrew's University researchers.
They found it had a 'potent and significant' effect against MRSA when combined with the antimicrobial lysostaphin. They said combining antibiotics prevented the emergence of resistant strains and also decreased toxicity to the patient.
Researcher Peter Coote said: 'Our finding represents a potentially novel way to combat MRSA via surface treatment or impregnation of wound dressings.'
Dr Coote added: 'The development of new routes to target MRSA that do not result in the acquisition of resistance would greatly improve the ability of clinicians to tackle these infections more effectively and cheaply.'
