In this study, we isolated and characterized a lytic phage, named vB_SmaM_PS2 (abbreviated as PS2), which can infect Serratia marcescens clinical isolates. Morphologically, phage PS2 can be classified within the Myoviridae family. The 167,276 bp double-stranded DNA genome of PS2 possesses 41.7% GC content. A total of 276 protein-coding genes and 4 tRNA genes were predicted in the PS2 genome. Of the 276 genes, 131 (47%) encoded T4-like genes, most of which are DNA replication and virion structural genes. Therefore, phage PS2 should be a new member of the T4-like Serratia phage.
在本研究中，我们分离并鉴定了一种裂解性噬菌体，命名为vB_SmaM_PS2（简称为PS2），它能够感染粘质沙雷氏菌临床分离株。从形态学上看，噬菌体PS2可归类于肌尾噬菌体科。PS2的167,276 bp双链DNA基因组的GC含量为41.7%。在PS2基因组中总共预测到276个蛋白质编码基因和4个tRNA基因。在这276个基因中，131个（47%）编码类T4基因，其中大多数是DNA复制和病毒粒子结构基因。因此，噬菌体PS2应该是类T4粘质沙雷氏菌噬菌体的一个新成员。
