Figure 6. In vitro testing of phage cocktails. (A) Four cocktails were tested for their effectiveness against each of four bacterial strains: PFR-Pl-2017, PFR-Pl-2006, W19-08100, and Pl-P1627. Strain Pl-P1627 was known to be resistant to all phages in this study; (B) Tables to summarize the results of cocktail testing and the substitution of Phage Callan for Phage Dash in Cocktails 2 and 4. Table colours represent the host range observations. Black: plaques; grey: full clearings; white: no infection. The symbols within the table record the overall effectiveness of the cocktail that phage is in on that host strain: +: effective cocktail; -/+: partially effective cocktail; -: ineffective cocktail.
