Dynamics of infectious virions and total number of virions produced in MDCK.SUS2 cells infected by A/PR/8/34-delS1(1) in a parallel continuous bioreactor system with residence times (RT) of 22 and 36 h, respectively. Experimental data (open circles) and model fit (solid lines) are shown for (A,B) TCID50 titer (infectious virion subpopulation of the FL S1-containing virions) and (C,D) HA titer which represents the sum of all viral subpopulations containing FL and DI S1. For both, experiment and model simulations, the continuous culture was started 23.4 h p.i.
