| Abstract: | In this paper, a model of competition between plasmid-bearing and plasmid-free organisms with pulsed input and washout were analyzed. We obtained that the extinct periodic solution is stable if pulsed period less than threshold, and the boundary periodic solution is stable if pulsed period more than threshold. Finally, we prove the system is permanence. |
