噬菌体(phage)是1917年由法国的d’Herelle率先发现的,它没有独立的代谢酶系,只能利用宿主细胞的生物合成机构进行核酸复制和蛋白合成以完成自身的增殖。除丝状噬菌体因其特殊的形态能从宿主逸出而不对宿主造成致命的后果外,其它所有噬菌体都在感染周期的晚期以特定的方 Phage was first discovered by d’Herelle in France in 1917. It does not have an independent metabolic enzyme system and can only utilize the host cell’s biosynthetic machinery for nucleic acid replication and protein synthesis to complete its own proliferation. In addition to filamentous phage because of its special morphology can escape from the host without causing fatal consequences for the host, all other phages in the late stages of the infection in a specific side
