FIGURE 6.

In vitro virulence of phage LPSent1 on free planktonic cells of S. Enteritidis EG.SmE1 at different multiplicity of infections (MOIs). The lysis activity of phage LPSent1 was evaluated at MOIs of 0.1, 1, 5, or 10. Bacterial cells were incubated for 24 h at 37°C, bacterial growth was monitored for 6 h by measuring optical density at 600 nm using a microplate reader (680 XR reader, Bio-Rad, Hercules, CA, USA). Data shown are the means of three replicates and error bars show the standard deviation in the values.
