Honey could be the new antibiotic, according to scientific research from the University of Wales Institute Cardiff (UWIC) presented today (Monday, 06 September 2004) at the Society for General Microbiology's 155th Meeting at Trinity College Dublin. By studying the way bacteria protect themselves from attack by forming slimy clumps, scientists have discovered that honey may be an effective new weapon in breaking up the microbes' defences. The researchers from the School of Applied Sciences at UWIC looked at the dangerous infections that commonly get into wounds, such as Pseudomonas bacteria.
"If the bacteria can multiply enough to form a slimy mass called a biofilm - the sort of slime you get round a sink plughole for instance - they are much less sensitive to antibiotics and antiseptics," says Ana Henriques of UWIC. "Doctors looking after badly injured and infected patients urgently need to remove these biofilms so that they can treat their wounds safely, and prevent the spread of antibiotic-resistant bacteria." The scientists studied six different strains of the bacteria, five of which came from injuries, and grew them in the laboratory to form biofilms, which are notoriously difficult to treat when they appear as hospital infections. Biofilms prevent healing in wounds and may lead to chronic ulcers. The laboratory grown samples were treated with Manuka honey, then unattached bacteria were washed off and the remaining slime layer studied after different time periods. In every sample the biofilm was disrupted making it more susceptible to the treatment with conventional antibiotics.
