在美国亚利桑那州立大学,一组科研人员种植带疫苗的番茄。希望能用它来挽救第三世界国家中每年死于腹泻的200万人,其中大部分是儿童。这种番茄从外观上看来与普通番茄没什么两样。但是它内部所含的丰富化学成分却使其成为真正的可食用疫苗。这种新的转基因番茄中所含的蛋白质外壳来自导致结肠炎的病菌,它使得番茄具有治疗作用——它不会导致人体患病,还能唤醒人体的免疫系统来对抗腹泻。 At Arizona State University in the United States, a group of researchers planted tomatoes with vaccines. It is hoped that it can be used to save up to 2 million people who die of diarrhea each year in third world countries, most of them children. This kind of tomato is no different from ordinary tomato in appearance. But its rich chemical content inside makes it a true edible vaccine. The new genetically modified tomato contains a protein shell derived from a colitis-causing germ that makes it a cure for tomatoes - it does not cause illness in the human body and can awaken the body’s immune system against diarrhea.
