In this paper. we study a fr.ctional-or.er.model with time-delay to descr.be the dynamics of Ebola vir.s infection with cytotoxic T-lymphocyte （CTL） r.sponse in vivo. The time- delay is intr.duced in the CTL r.sponse ter. to r.pr.sent time r.quir.d to stimulate the immune system. Based on fr.ctional Laplace tr.nsfor., some conditions on stability and Hopf bifur.ation ar. der.ved for.the model. The analysis shows that the fr.ctional- or.er.with time-delay can effectively enr.ch the dynamics and str.ngthen the stability condition of fr.ctional-or.er.infection model. Finally, the der.ved theor.tical r.sults ar. justified by some numer.cal simulations.
