The spread of malaria is like a two-way street.The disease is spread to humans through the bite of mosquitoes infected with malaria parasites,the most dangerous of theses being plasmodium falciparum.Uninfected mosquitoes become infected with the parasite by biting infected animals

疟疾的传播像个双向道 . 一条是人们通过被感染了疟疾寄生虫的蚊子感染 , 其中最危险的是 恶性疟原虫 . 另一条则是未感染的蚊子因为叮了感染有寄生虫的动物而得病 .

In sub-Saharan Africa and parts of Asian,an estimated 300 million people are infected every year,more than one million of them are children, many of whom die.Years of attempting to cure the disease with antibiotics and quinine drugs have caused the parasite to become resistant to treatment.

在撒哈拉以南的非洲和亚洲一些地区 , 每年有大约 3 亿人们被感染 , 其中 100 万以上是孩子 , 许多已死亡 . 因为长期使用抗生素和奎宁治疗这种疾病 , 如今这种寄生虫已经产生了抗药性 .

Scientist are trying to come up with noval strategies for conquering malaria.One idea that has been around for a number of years is the creation of genetically altered mosquitoes that could be released into the environment.

科学家正在努力试图用新的方略来对抗疟疾病 . 其中一个流行了许多年的想法便是创造转基因蚊子再释放到大自然中 .

The so-called transgenic insects would be resistant to infection by falciparum.Through breeding,the altered insects would gradually replace the population of mosquitoes capable of becoming infected with the parasite.

这种转基因昆虫可以抵抗 恶性疟原虫的感染 . 通过代代繁殖 , 这种昆虫可以逐渐取代容易被寄生虫感染的蚊子种群
