Phage density depends on phage aggressiveness and replication speed. (a) Schematic of phage (red symbols) spreading on lattice; solid (dashed) squares are bacteria colonies (space). (b) Mean-field model phage density. (c) Numerical results of lattice model for phage dynamics. (d) Schematic illustration of growth of phage (red) and bacteria (black) for two different values of phage speed w represented by the changing length of the red arrows. The color bar corresponds to density in panels b and c.
