FIG. 2.

Virus yield and viral DNA replication of HF infected with wild-type (WT) and pp28STOP50 viruses (MOI, 0.01). Cells and supernatants from 35-mm dishes infected with the wild type and the pp28STOP50 virus were combined, and titers were determined as described in Materials and Methods. Viral genome copy numbers were determined by real-time PCR as previously described and reported as a log of the copy number (24).
