Figure 6:

Uncertainty of the states: (a) susceptible of E. coli (S_e), (b) susceptible of P. multocida (S_m), (c) resistant of E. coli (R_e), and (d) resistant of P. multocida (R_m). These distributions are by ODE solution of model (1) for 150 hours having the uniformly distributed parameters input given in the Table 2. The drug dose is 5 mg/kg three times in this case. The dark red curves represent the average solution curves (median) of the states obtained from the uncertainty distribution. Other light pink, pink, and dark pink ribbons represent the solutions in 25–75 quantiles of the uncertainty distribution of states.
