In this study, a novel Escherichia coli-specific bacteriophage, vB_EcoM_IME392, was isolated from chicken farm sewage in Qingdao, China. The genome of IME392 was found by next-generation sequencing to be 116,460 base pairs in length with a G+C content of 45.4% (GenBank accession number MH719082). BLASTn results revealed that only 2% of the genome sequence of IME392 shows sequence similarity to known phage sequences in the GenBank database, which indicates that IME392 is a novel bacteriophage. Transmission electron microscopy showed that IME392 belongs to the family Myoviridae. The host range, the multiplicity of infection, and a one-step growth curve were also determined.
在这项研究中,从中国青岛的养鸡场污水中分离到一株新型的大肠杆菌特异性噬菌体 vB_EcoM_IME392。通过下一代测序发现,IME392 的基因组长度为 116460 个碱基对,GC 含量为 45.4%(GenBank 登录号 MH719082)。BLASTn 结果表明,IME392 的基因组序列只有 2%与 GenBank 数据库中已知噬菌体序列具有序列相似性,这表明 IME392 是一种新型噬菌体。透射电子显微镜显示,IME392 属于肌尾噬菌体科。还确定了 IME392 的宿主范围、感染复数和一步生长曲线。
