Dynamics and Stability Analysis of a Brucellosis Model with Two Discrete Delays

Figure 1

Stability of the infected and free-infected equilibrium of model system (1) showing plots of and with varying delay . The direction of the arrow depicts an increase in delay with a step size of starting from 2.0 to 10. The blue patterns in both (a) and (b) highlight brucellosis dynamics when while the red pattern is for Initial population levels were assumed as follows: animals, animals, animals, and animals.
