FIG. 6.

Growth of T3C84 and T3C84-MA in L cells (A) and MDCK cells (B) after viral adsorption at a low MOI. Cells (2 × 10⁵) were infected with either T3C84 or T3C84-MA at an MOI of 0.001 PFU per cell. After adsorption for 1 h, the inoculum was removed and cells were incubated at 37°C for the times shown. Titers of virus in cell lysates were determined on L-cell monolayers by plaque assay. The results are presented as the mean viral titers for three independent experiments. Error bars indicate standard deviations of the means.
