The internalization efficiency of phage particle towards Vero cells. Vero cells (5.0 × 105 cells/ well) were incubated with 108 pfu phages, thoroughly washed to remove unbound phages, and then the output phages were divided into Elution, PEW and Lysate. Bacteria were infected with each fraction to determine output phage titer by pfu assay. Data represent mean ± S.E of 3 independent tests
