Effect of phages A) phi-IPLA5 and B) phi-IPLA7 on a lawn of S. epidermidis . I) Morphology of phage lytic zone when dropped on different S. epidermidis strains. (S) Sensitive strain; (R) resistant strain; (DS) drop-sensitive strain. II) Bacteria viable number in drop-zone (white), bacteria lawn (black) and phage titre (grey) of phages. Each value correspond with the mean of five different experiments, the standard error is represented by bars.
