Growth and Replication of Infectious Bursal Disease Virus in the DF-1 Cell Line and Chicken Embryo Fibroblasts

Figure 4

Analysis of virus titers in DF-1 and chicken embryo fibroblasts (CEF) cells at various hours postinfection using TCID50. Cell culture flasks (25 cm2) containing confluent monolayers of CEF or DF-1 cells were inoculated with 0.1 MOI of IBDV. Virus media were then harvested at indicated time points for titration using TCID50. The data represent the mean titer and standard deviation for each time point of the triplicate assays. Means with common letters are not significantly different at .
