Characterization and Genomic Study of Phage vB_EcoS-B2 Infecting Multidrug-Resistant Escherichia coli.

ABSTRACT: The potential of bacteriophage as an alternative antibacterial agent has been reconsidered for control of pathogenic bacteria due to the widespread occurrence of multi-drug resistance bacteria. More and more lytic phages have been isolated recently. In the present study, we isolated a lytic phage named vB_EcoS-B2 from waste water. VB_EcoS-B2 has an icosahedral symmetry head and a long tail without a contractile sheath, indicating that it belongs to the family Siphoviridae. The complete genome of vB_EcoS-B2 is composed of a circular double stranded DNA of 44,283 bp in length, with 54.77% GC content. vB_EcoS-B2 is homologous to 14 relative phages (such as Escherichia phage SSL-2009a, Escherichia phage JL1, and Shigella phage EP23), but most of these phages exhibit
