摘要
Abstract
In view of an exchanging information mechanism of bacteria,a delayed epidemic model with the competition between bacteria and the immune system is formulated. In the sequel, the existence and stability of the positive equilibrium are investigated, respectively. Then,the existence and direction of Hopf bifurcation are discussed. At last,numerical simulations are curried out to verify the theory results,and which provide theory and numerical basis to control and prevent the epidemic disease.关键词
