Australian researchers claim breakthrough on dengue fever
Australian researchers funded by US billionaire Bill Gates Friday claimed a breakthrough which could help in the fight against dengue fever by stopping the often deadly disease in its tracks.
University of Queensland researchers said they have successfully infected the mosquito which spreads the tropical disease with a bacterium which halves its 30-day lifespan, thereby reducing its ability to transmit dengue to humans.
Scientists hope their work will help halt the spread of the painful and debilitating disease which affects millions of people each year.
The key is that really only very old mosquitos are the only ones that are able to transmit the disease," said researcher Professor Scott O'Neill.
"What we've done is put this naturally occurring bacteria into the mosquitos that actually halves their adult lifespan so they don't live long enough to be able to transmit the virus."
The research published Friday in the journal Science is the result of injecting 10,000 mosquito embryos with a bacterium that occurs naturally in fruit flies but has never been detected in dengue-carrying mosquitoes.
O'Neill said the test was designed to see whether the bacterium reduced the lifespan of the insects without killing them or preventing them from breeding and was able to be passed on to offspring.
He said while the laboratory tests, which involved researchers allowing the bacteria-infected mosquitoes to bite their arms because the species needs human blood to breed, had been successful, it would be several years before the technique would be tested in the wild.
"It's really a preventative strategy for preventing dengue fever outbreaks and what we've done is show that it's possible to be done in a laboratory," he told AFP.
"The next stage is now to move it into a more realistic field setting."
There is no known cure or vaccine for dengue fever, which is transmitted by mosquitos and kills more than 20,000 people each year. Also known as "breakbone fever," symptoms include high temperatures and muscle aches.
The Bill and Melinda Gates Foundation donated 10 million dollars to an international research team led by the University of Queensland into a means of defeating dengue fever in 2005.
I would like to share this interesting discovery from a classmate's son who has just recovered from dengue fever. Apparently, his son was in the critical stage at the ICU when his blood platelet count drops to 15 after 15 liters of blood transfusion.
His father was so worried that he seeks another friend's recommendation and his son was saved. He confessed to me that he gave his son raw juice of the papaya leaves. From a platelet count of 45 after 20 liters of blood transfusion, and after drinking the raw papaya leaf juice, his platelet count jumps instantly to 135. Even the doctors and nurses were surprised. After the second day he was discharged. So he asked me to pass this good news around.
Accordingly it is raw papaya leaves, 2pcs just cleaned and pound and squeeze with filter cloth. You will only get one tablespoon per leaf. So two tablespoon per serving once a day. Do not boil or cook or rinse with hot water, it will loose its strength. Only the leafy part and no stem or sap. It is very bitter and you have to swallow it like "Won Low Kat". But it works.
*Papaya Juice - Cure for Dengue*
You may have heard this elsewhere but if not I am glad to inform you that papaya juice is a natural cure for dengue fever. As dengue fever is rampant now, I think it's good to share this with all.
A friend of mine had dengue last year. It was a very serious situation for her as her platelet count had dropped to 28,000 after 3 days in hospital and water has started to fill up her lung. She had difficulty in breathing. She was only 32-year old. Doctor says there's no cure for dengue. We just have to wait for her body immune system to build up resistance against dengue and fight its own battle. She already had 2 blood transfusion and all of us were praying very hard as her platelet continued to drop since the first day she was admitted.
Fortunately her mother-in-law heard that papaya juice would help to reduce the fever and got some papaya leaves, pounded them and squeeze the juice out for her. The next day, her platelet count started to increase, her fever subside. We continued to feed her with papaya juice and she recovered after 3 days!!!
Amazing but it's true. It's believed one's body would be overheated when one is down with dengue and that also caused the patient to have fever papaya juice has cooling effect. Thus, it helps to reduce the level of heat in one's body, thus the fever will go away. I found that it's also good when one is having sore throat or suffering from heat.
