“A way to stop the spread of the insects transmitted diseases is to make the blood of animals and humans toxic”, according to researchers, who claim that the discovery could mean “a new and promising complementary tool” for this purpose. ”
Some researchers have discovered that a medicine that is usually prescribed for rare diseases can do the human blood sea Deadly for mosquitoeswhich offers a Possible track To stop diseases such as malaria.
The group experience With a drug called Nitsonathat people are generally prescribed Rare hereditary diseases which normally prevent them from being able to completely decompose some amino acids. Medicine acts by blocking an enzyme to avoid the accumulation of harmful by the products of the disease in the human body.
When mosquitoes drink blood that also contains Nisinona, the drug Blocks the enzyme in their bodiesBy preventing them from correctly digesting the blood, which leads them to die quickly, according to the results published in the magazine “Science Translational Medicine”.
“A form of stop the spread of the diseases transmitted by insects It is to make the blood of animals and human beings to these hematifagi insects toxic “, says Lee R. Haines, associate professor of research at the University of Notre Dame (USA) and the main author of the study.
“Our results suggest that the use of Nisinone could be A new and promising complementary tool To control the diseases transmitted by insects such as malaria. “Personal protection measures include the transport of clothes they cover, the use of a mosquito repellent and the use of mosquito networks or mosquito networks on doors and windows.
A growing need for solutions to control mosquitoes
Another method is the use of Ivemectinused to kill parasites. However, it is Repeated use can cause resistance to the drug. It can also be toxic to the environment. “Nisinona’s performance was fantastic,” says Álvaro Acosta Serrano, professor of biological sciences at Notre Dame and Co -Author of the study.
“He has a semi -blood experience in human blood much longer than Irmectin, which means that his mosquito activity remains circular in the human body for much more time. This is essential if applied to the ground for economic and safety reasons, “he adds.
Nisinona has been able to kill mosquitoes of all age groups, including the oldest, which are more likely to transmit malaria. It was also able to eliminate insecticide resistant mosquitoes.
“In the future, It could be advantageous alternative nisinone and ivemectin To check mosquitoes, “says Haines.” For example, nisinone could be used in areas where resistance to iremectin persists or where it is already used a lot for cattle and humans. “
Among the diseases transmitted by mosquitoes there are malaria, the denseThe western Nile virus, the chikungunya fever and the yellow fever, according to the European Center for the prevention and control of diseases (ECDC). They represent one Emerging threat for human health in Europefrom the Climate change creates more favorable conditions For species of invasive mosquitoes, despite the fact that malaria has been uprooted for several decades of the continent.
