| Abstract: | An eco-epidemiological SIS model with stage and disease in the predator is investigated. The threshold is founded which the epidemic will become endemic or die out.For locally asymptotical stability and globally asymptotical stability of disease-free equilibrium and the endemic equilibrium sufficient conditions are obtained for this model. |
