Cyber Daily News - Scientists produce strains of mosquitoes that carry genes that can
block the transmission of malaria in the hope of breeding them with
other members of their species in the wild and produce offspring that
can not spread the disease.
Researchers on Monday (23/11) said they use the editing of genes, genetic engineering techniques in which DNA can be inserted, changed or deleted from the genome, the Anopheles stephensi mosquito species that spread malaria in urban areas of India.
They insert DNA into the germline, the cells that pass on genes from generation to generation, the species and produce mosquitoes with genes that could prevent the transmission of malaria by producing antibodies blocker which 99.5 percent will be passed to offspring.
Malaria is caused by a parasite that is transmitted to humans through the bite of a female mosquito that is infected.
The release of the mosquitoes that have been genetically modified to do so they could mate with wild mosquitoes so that the malaria genes blocking their entry into the gene pool and eventually surpassed the population, shortening the current ability of the species to infect people with the parasite.
"It can be spread in a population with a very big efficiency, increased from one percent to 99 percent in 10 generations, or about one season for mosquitoes," said Valentino Gantz biologist from the University of California-San Diego.
Biologists from the University of California-San Diego others, Ethan Bier, called the mosquito as "a powerful tool in sustainable malaria control" because it will make all the mosquitoes in an area having the genes of anti-malarial.
"We do not claim that this strategy alone will eradicate malaria," said molecular biologist University of California-Irvine, James Anthony.
But along with medications for prevention and treatment, future vaccines, mosquito nets blocker and mosquito eradication, James said, could play a major role in sustainable malaria elimination efforts.Other scientists are also working to produce mosquitoes genetically engineered.
Last year a group of scientists produced a strain of mosquitoes that carry the gene that carries almost the entire male offspring, which could lead to wild mosquito populations plummeted.
"In contrast, our system is more flexible only prevent mosquitoes from carrying malaria but does not harm the mosquitos. So this should cause less ecological damage," said Bier on the results of research published in the Proceedings of the National Academy of Sciences.
The World Health Organization (World Health Organization / WHO) estimates there will be 214 million cases of malaria caused 438,000 deaths worldwide in 2015, mostly in sub-Saharan Africa, such as reported by Reuters news agency.
