Major Natural Antibiotic Discovered
An
antibiotic that kills all bacteria, including super bacteria that have
developed resistance to other antibiotics. It is a honey that can be bought at
a health food store.
Australian
researchers have been astonished to discover a cure-all right under their noses
— a honey sold in health food shops as a natural medicine.
Far from
being an obscure health food with dubious healing qualities, new research has
shown the honey kills every type of bacteria scientists have thrown at it,
including the antibiotic-resistant “superbugs” plaguing hospitals and killing
patients around the world.
Some
bacteria have become resistant to every commonly prescribed antibacterial drug.
But scientists found that Manuka honey, as it is known in New Zealand,
or jelly bush honey, as it is known in Australia, killed every bacteria or
pathogen it was tested on.
It is applied externally and acts on skin infections, bites and cuts.
The honey is
distinctive in that it comes only from bees feeding
off tea trees native to Australia and New Zealand, said Dee Carter, from the
University of Sydney’s School of Molecular and Microbial Biosciences.
The findings
are likely to have a major impact on modern medicine and could lead to a range
of honey-based products to replace antibiotic and antiseptic creams.
Professor
Carter’s two sons, Marty, 8 and Nicky, 6, think it’s funny the way their mother
puts honey on
their sores. But she swears by it, telling stories of how quickly it cures any
infection.
“Honey
sounds very homey and unscientific, which is why we needed the science to
validate the claims made for it,” she said.
The curative
properties of various types of honey have been known to indigenous cultures for
thousands of years, and dressing wounds with honey was common before the advent
of antibiotics.
“Most bacteria that cause infections in hospitals are resistant to at least one
antibiotic, and there is an urgent need for new ways to treat and control
surface infections,” Professor Carter said.
“New
antibiotics tend to have short shelf lives, as the bacteria they attack quickly
become resistant. Many large pharmaceutical companies have abandoned antibiotic
production because of the difficulty of recovering costs. Developing effective
alternatives could therefore save many lives.”
Professor
Carter said the fascinating thing was that none of the bacteria researchers
used to test the honey, including superbugs such as flesh-eating bacteria,
built up any immunity.
She said a
compound in the honey called methylglyoxal — toxic on its own — combined in
unknown ways with other unidentified compounds in the honey to cause
“multi-system failure” in the bacteria.
The results of the research project are published in this month’s European Journal of Clinical Microbiology and Infectious Diseases.
