Manuka honey, the premium product found on fashionable breakfast tables, could play a role in the battle against antibiotic-resistant superbugs, scientists reported yesterday.
Honey is known to have antiseptic properties but the antibacterial potency of manuka honey, from New Zealand, is 10 to 50 times more powerful. It has been shown to stop the growth of antibiotic-resistant Staphylococcus aureus – the superbug that causes MRSA.
Manuka honey is derived from nectar collected by honey bees foraging on the manuka tree in New Zealand and is included in modern wound-care products such as dressings and ointments available on NHS prescription. However, its antimicrobial properties have not been fully exploited, according to researchers.
Laboratory studies by Professor Rose Cooper and colleagues at the University of Wales Institute, Cardiff, show that manuka honey interacts with three bacteria that commonly infect wounds – MRSA, Pseudomonas aeruginosa and Group A streptococci.
"Our findings suggest that manuka honey can hamper the attachment of bacteria to tissues which is an essential step in the initiation of acute infections. Inhibiting attachment also blocks the formation of bio-films, which can protect bacteria from antibiotics and allow them to cause persistent infections," Professor Cooper said.
The U.S. government has given an ultimatum to the international group that helps provide vaccines to...
