Manuka honey is from bees which have collected nectar from manuka trees – better known as tea trees – in New Zealand and Australia.

Tea tree oil has long been feted for its anti-bacterial properties.

However, scientists at Cardiff University say that the honey could also be a useful “topical agent”.

Prof Rose Cooper, of its Centre for Biological Sciences, said: “Our findings with streptococci and pseudomonads [bacteria] 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 biofilms, which can protect bacteria from antibiotics and allow them to cause persistent infections.”

She added: “Other work in our lab has shown that honey can make MRSA more sensitive to antibiotics such as oxacillin – effectively reversing antibiotic resistance.

“This indicates that existing antibiotics may be more effective against drug-resistant infections if used in combination with manuka honey.”

Putting the honey on wounds could be a novel and economic way of reducing infections, she suggested.

“The use of a topical agent to eradicate bacteria from wounds is potentially cheaper and may well improve antibiotic therapy in the future.”
