In this paper, we consider a mathematical model for phage growth in a two-stage chemostat, taking account of the delay from infection to lysis. We give sufficient conditions for the globally asymptotic stability of noninfected equilibrium and obtain sufficient conditions for the local stability of infected equilibrium. We also perform some numerical simulations which illustrate the theoretical results obtained. The formula for R0 shows that decreasing the delay and/or increasing the burst size will inc...
