Bees - A Potential Help Against MRSA Bugs

Bees could be the vital contributor to new treatments that are critical in fighting the virulent MRSA bug, states a new research at the University of Strathclyde.

The researchers found that a substance known as beeglue or propolis, originating from beehives in the Pacific region, was active against MRSA, which causes potentially fatal infections, particularly in hospital patients.

MRSA infection is the most dreaded hospital or community acquired infection that can become life-threatening.

Dr Veronique Seidel, a Lecturer in Natural Products Chemistry at the Institute, led the research.

She said: "MRSA can have a devastating impact on people who contract it and on their families, often compounding illnesses they already have. One of the few available drugs to treat MRSA infections is an antibiotic called vancomycin. But new strains have been emerging which show limited susceptibility, or even resistance, to vancomycin.

"This means that there is a pressing need to discover and develop alternatives to current anti-MRSA drugs. We investigated propolis, as part of a programme aimed at discovering new antibiotics from natural sources, because bees use it as an antiseptic glue to seal gaps between honeycombs and preserve their hives from microbial contamination.

Birth defects are abnormalities, which occur before the birth of the baby and can be caused due to genetic, environmental and other unknown reasons.

"Beeglue is also a natural remedy widely-used in folk medicine for a variety of ailments but little has been known until now about its capacity to target MRSA. Our results have been highly encouraging and we will be taking our research further to understand how active substances in propolis work and to seek the treatments which patients urgently require," she added.

The Strathclyde researchers have been working in partnership with Nature's Laboratory in North Yorkshire, a world leader in propolis research and campaigner for deeper scientific understanding of natural medicines.

Study to Determine How Consumers Choose Among Alternative Medicines
Alternative health remedies have gained immense popularity in the health care marketplace. Now, a new study sheds light on how people choose among the various available remedies.

They tested extracts of propolis on 15 MRSA strains obtained from the NHS and isolated two compounds, Propolin C and Propolin D, which showed good activity against all the MRSA strains tested.

The research is the first to report anti-MRSA activity in propolis originating from the Pacific region and the first to describe the anti-MRSA properties of Propolin C and Propolin D. These could possibly act as templates for the development of improved anti-MRSA agents.
