Abstract
Infectivity titre and haemagglutination titre of PI-3 virus in MDBK cells using monolayer, suspension and roller systems revealed that the roller system produced the highest infectivity and haemagglutination in-hibition titre with an increase of loge 08 than their corresponding mono-layer cell culture. On the other hand, the infectivity and HA titres in cell suspension cultures were 1.0 logs 0 lower than their corresponding mon-olayer cell culture system. Influence of DEAE-Dextran for the enhancement of P1-3 virus in-fectivity in different cell culture systems, 25ug of DEAE-Dextran per ml is considered the safest concentration to the MDBK and VERO cell lines and giving these results: 1.Infectivity titre of PI-3 virus was markedly increased under the effect of both serial passages, and showed an increase of 1.5 logs 0 and 1.3 loge 0, respectively, more than their respective non-treated passages. 2.In the roller system, DEAE-Dextran enhanced the growth of virus by about 1.0 logi 0 and 1.2 logi 0 more than growth of untreated virus in both MDBK and VERO cell lines, respectively. 3.The highest titre obtained when using DEAE-Dextran MDBK roller sys-tem was 9.5 logs o.
