Bacterial densities and proportion resistant in the phage cocktail passaging experiment

Bacterial densities and proportion of resistant colonies (as determined via plating on “phage agar”) after each passage of the phage cocktail passaging experiment. “CFUperml” has been calculated as the CFU per ml culture (in vitro lines) or CFU per 1 mm2 tissue (in planta lines), and any values below the limit of detection were recorded as being at that limit (as a conservative estimate of density). “Propres” is the proportion of colonies that grew on the “phage agar” plate relative to the non-phage plate, and “Propres_minusPT23prop” has had the proportion of colonies from the control plate subtracted from the sample proportions. “Sample” is the evolution line identifier, “Treatment” is passaging treatment, “Environment” is the passaging environment, “Week” is the passage number, “Phage” indicates whether phage was present on the CFU plate, and “Week” is the passage number. Results are presented in Figure 5.
