Three share Nobel medicine prize for beating parasites
Oct.5, Stockholm: This year's Nobel Prize for medicine has been awarded to researchers from China, America and Japan who have made important contributions towards tackling human diseases in developing parts of the world.
Tu Youyou, the first-ever Chinese medicine laureate, will share the eight million Swedish kronor (about $960,000) award with Japanese microbiologist Satoshi Omura and an Irish-born U.S. scientist William Campbell.
William Campbell and Satoshi Omura were awarded the prize for their work on a therapy against roundworm and combating parasites in humans.
Satoshi Omura isolated bacteria from soil samples in Japan, looking for those that appeared most promising in combating microorganisms.
The efficacy of the bacteria was then tested by William Campbell. He discovered one of them was remarkably efficient against parasites in domestic and farm animals.
The result was the drug, Avermectin, which has radically lowered the incidence of River Blindness and Lymphatic Filariasis, and has been effective against a number of other parasitic diseases.
