GM mozzies battle malaria

Researchers have created genetically-modified mosquitoes resistant to a malaria parasite, raising the possibility of one day stopping the spread of the disease, a new study says.

US researchers have created genetically-modified mosquitoes resistant to a malaria parasite, raising the possibility of one day stopping the spread of the disease, a new study says.

GM mozzies wins evolution race
The genetically-altered insects survived in greater numbers and laid more eggs. After nine generations, 70 percent of the mosquitoes were genetically-modified compared to 50 percent at the outset of the experiment, Marcelo Jacobs-Lorena and his colleagues wrote.

The study suggested that when feeding on malaria-infected blood, "transgenic malaria-resistant mosquitoes have a selective advantage over non-transgenic mosquitoes," the authors wrote.

Not ready for prime time
Further research was still needed before the altered insects could be released into the wild, as only a small percentage of mosquitoes in nature are exposed to malaria, the authors wrote.
