Beschreibung
Zusammenfassung:	The invention belongs to the technical field of escherichia coli phage, and particularly relates to a broad-spectrum escherichia coli phage capable of cracking four bacteria and an application of the broad-spectrum escherichia coli phage to sterilization and bacterium prevention. The invention mainly discloses an escherichia coli phage EC35P1 (Escherichia coli phase EC35P1), and the preservation number of the escherichia coli phage EC35P1 is CCTCC M 2020438. The phage is a virulent phage separated from the nature, tests prove that the phage has no toxic effect on normal microbial flora, and DNA of the phage cannot encode virulence genes and is high in stability. The phage is wide in host range, can be used for cracking escherichia coli, shigella, salmonella and enterobacter cloacae, and large-scale industrial production can be realized. The phage provides an excellent strain resource for developing a novel antibacterial preparation, and has a good application and development prospect. 本发明属于大肠杆菌噬菌体技术领域，尤其涉及一株能
