The invention discloses a salmonella phage RDP-SA-21003 capable of simultaneously cracking escherichia coli, the preservation number is CGMCC No.22494, and after sequencing of the whole gene, the salmonella phage RDP-SA-21003 does not have virulence genes and lysogenic genes; the cracking efficiency of the obtained phage on host bacteria BS20078 is over 98.7 percent, and when the phage is used alone, the cracking capacity on salmonella is relatively strong, and the cracking spectrum is wide; moreover, the bacteriophage RDP-SA-21003 has the capability of cracking Escherichia coli causing chicken airsacculitis and peritonitis. |
