All around the world, around 1 million people are killed by Malaria every year.
In an interesting development, researchers in Arizona have come up with a genetically modified strain of mosquitoes, which are resistant to malaria. The study appeared online in the journal PLoS Pathogens.
This has been made possible by changing a single gene in the mosquitoes.
In the study the scientists injected the malaria parasite in 90 genetically modified breeds. After a span of 10 days it was seen that these mosquitoes do not have the malaria parasite.
However, scientists revealed that it is not possible that these mosquitoes will not be available as of now. This is the first time when there has been a 100% prevention of the malaria parasite.
The cellular signaling gene present in the mosquitoes was altered by the scientists. The immune response of the mosquitoes is impacted by the signaling process. This process also effects the duration of life of the mosquitoes.
Therefore, the alterations in the gene were done in order to make insects, which died early. The malaria parasite requires 16 days to activate in the gut of mosquitoes and these altered mosquitoes died before that.
Professor Michael Riehle from the University of Arizona, the Head of the study, said that they were expecting only a slight reduction, but they were surprised when there was a complete blockage of the parasite.
