Isolation and purification of the Salmonella phage vB_SalP_LDW16. A Sample filtrate displays the clear phage plaques on the double-layer plate overlays with suspensions of Salmonella after incubation for 24 h, depicting lysed bacteria, 1–8 represent partial filtrate samples. B The phage vB_SalP_LDW16 crude filtrate. After 24 h of incubation, clear and different sized plaques were displayed on the Salmonella lawn. C The purified phage vB_SalP_LDW16 displays clear and uniform patched plaques on a Salmonella lawn after incubation for 24 h
