Figure 2.

Rate of evolution of phage ϕNV3 through time. The experimental coevolution was performed by inoculating King’s medium B (KB) with phage ϕNV3 and Pseudomonas agarici NCPPB 2472. After 48 h incubation at 27 °C, both bacteria and phage were recovered and transferred to fresh KB. This was repeated for 10 transfers. Each line represents the resistance of bacteria to past (the previous transfers), current (the present transfer) and future (the subsequent transfers) phage. Values are mean of 5 replicates +/− SEM.
