Figure 4

HA (2 mg/ml) was added at different time points within a single viral replication cycle (7 h for COXB5, 18-20 h for HSV-1). In parallel wells, HA was added together with the virus inoculum (T = 0). At the end of the replication cycle, cell cultures were frozen and the virus yield was titrated by end point titration (COXB5, panel A) or plaque assay (HSV-1, panel B). The results are expressed as Log of the TCID50 in panel A, as PFU/ml in panel B. * p < 0.05 with the Student's t test in comparison with HA untreated controls.
