- Abstract
Objective To isolate and identify the Salmonella lytic phage, and determine the physiological characteristics and antibacterial ability, so as to screen advantageous phages for the development of phage inhibitors. Method The Salmonella phage was isolated from farmers’ market effluent by the spot test using Salmonella agona CICC 21586 as the host bacterium, its physiological characteristics were studied, and its bacteriostatic effect in milk and chicken meat was measured. Result A Salmonella phage SalmpYZU27 was isolated, which had a wide lysis spectrum and could lyse 12 Salmonella strains such as Salmonella typhimurium CICC 21483, Salmonella paratyphic-C CICC 21512, and Salmonella enterica strain 2011K-1440 chromosome N16, the optimal infection complex was 0.001, it remained highly active at pH 4-11, the incubation period was 20 min, the outbreak period was 100 min, and the outbreak was 89 PFU/cell.
