摘要：
In this study, we present the complete, annotated genome of a new member of the Tequatrovirus (T4-like) genus, Escherichia phage vB_EcoM_C2-3. This phage has an isometric head (92 nm in diameter) and a contractile tail (114 nm in length). Its genome consists of a linear, double-stranded DNA of 167,069bp with an average G+C content of 35.3%. There are 267 predicted genes, of which 125 encode functional proteins, including those for DNA replication, transcription and packaging, phage morphogenesis and cell lysis. Neither genes involved in the regulation of lysogeny nor antibiotic resistance genes were identified. Based on our results, its genomic features provide valuable insights into the use of a potential biocontrol agent, as Escherichia phage vB_EcoM_C2-3 exhibited lytic activity against E. coli, including multidrug-resistant strains.
