诺维氏梭菌是一种常见的厌氧菌,其释放的酶可以刺穿并杀死哺乳动物细胞。美国生物科技公刊“生物医疗谷发现”公司研究团队对诺维氏梭菌进行了基因改造,剔除了产生毒素的主要基因,使其不会构成严重的健康风险,然后将转基因细菌注射到16只实验狗的肿瘤内。三个星期后,有9只狗体内的肿瘤已经萎缩或者消失。研究人员随后在一位5 3岁的女性身上进行了细菌疗法的人体测试。这位女性体内的癌细 Clostridium novyi is a common anaerobic bacterium that releases enzymes that can penetrate and kill mammalian cells. The US biotech publication, Biomedical Valley Discovery team, genetically engineered Clostridium norvei to remove the major toxin-producing genes from serious health risks and then inject the genetically modified bacteria into Tumor in 16 experimental dogs. Three weeks later, the tumors in nine dogs had shrunk or disappeared. The researchers then conducted a human test of bacterial therapy on a 53-year-old woman. The woman’s cancer in the body
