Phages are a special kind of virus because they only infect and kill bacteria. They don't infect humans or other animals.
噬菌体是一种特殊的病毒,它只会感染和杀死细菌,不会感染人类或其它动物。
Both these are virulent phages, meaning that whenever a phage particle attacks a bacterial cell that cell is inevitably killed.
它们都是烈性噬菌体,也就是说这种病毒颗粒一旦侵袭细胞,细胞就必然死亡。
The competition between bacteria and phages is not only the result of their own selection pressure, but also the dynamics of their co-evolution.

Typical phages have hollow heads that store their viral DNA and tunnel tails with tips that bind to specific molecules on the surface of their target bacteria.
典型的噬菌体有存储它们病毒DNA的空心头部和带有尖端的隧道式尾巴,此尖端表面有它们的目标细菌的分子。
噬菌体(phages)是"bacteriophage"的简称,源自希腊语"细菌吞噬者",指一类特异性感染细菌的病毒。这类微生物由英国细菌学家Frederick Twort于1915年首次发现,加拿大微生物学家Félix d'Hérelle在1917年正式命名(来源:Nature Reviews Microbiology。
从结构特征看,噬菌体由蛋白质衣壳包裹遗传物质(DNA或RNA)构成,典型结构包括二十面体头部和可收缩尾部(来源:NCBI。其作用机制包含吸附、核酸注入、生物合成、组装和释放五个阶段,通过裂解或溶原两种生命周期调控宿主菌。
