摘要：Migratory birds are critical to the prevalence of many epidemic diseases. In this paper, a new two species eco-epidemiological model with disease in the migratory prey is formulated. A modified Leslie-Gower functional scheme, with saturated incidence and recovery rate are considered in this new model. Through theoretical analysis, a series of conditions are established to ensure the extinction, permanence of the disease, and to keep the system globally attractive. It was observed that if the lower threshold value R ∗ > 1 $R_{*}>1$ , the infective population of the periodic system is permanent, whereas if the upper threshold value R ∗ ≤ 1 $R^{*}\leq1$ , then the disease will go to extinction. Our results also show that predation could be a good choice to control disease and enhance permanence.
