听写总结
MJ-Lorena is with the MalariaResearchInstitute at Johns Hopkins University in Baltimore,Maryland,JL saysinvestigators created genetically engineered mosquitoes that were more hardy than so-called wild-type mosquitoes that carry the parasite, and put the blood sucking insects to the test.In an article published in the journal Proceedings of the National Academy of Sciences ,JL and colleagues report having an equal number of genetically engineered mosquitoes and wild-type insects feast on a malaria-infected mouse.After 9 generations, the percent of altered mosquitoes increased from 50% to 70 percent.

称研究人员培育出了一种转基因蚊子
,
这种蚊子比野生蚊子更能抵御寄生虫的感染
,
在对这些吸血昆虫进行实验后
,ML
和他的同事在国家科学期刊杂志上面发表论文声称
,
将相同数量的转基因蚊子和野生蚊子一起食用被疟疾感染的老鼠

经过

代之后

发现转基因的蚊子数量由原来
50%
上升到
70%.
If and when the scientists are able to breed transgenic mosquitoes in numbers that might make a difference in the spread of malaria, JM says researchers have to make sure such insects do not cause anunforeseen harm.
“We have to be absolutely sure that any genetically modified mosquito doesn’t cause any harm in the environment or cause unpredictable harm to people that they bite.”
如果科学家可以繁殖大量转基因蚊子那势必会对疟疾的传染有所帮助
.JM
说研究人员须确定这种昆虫不会造成无法预见的伤害

“
我们必须确定转基因蚊子不会对环境和其叮咬的人们造成无法预知的伤害
”
Despite the obstacles,JL is optimistic that genetically altered mosquitoes will one day take their place alongside other strategies to fight Malaria.

仍对未来转基因蚊子可以与其他方法搭配一同对抗疟疾上保持乐观
