From: PA from an H5N1 highly pathogenic avian influenza virus activates viral transcription and replication and induces apoptosis and interferon expression at an early stage of infection

Figure 2

Multi-step growth curves of C-PA and WSN in infected cells. MDCK (A), chicken embryo fibroblast (CEF) (B), and Vero (C) cells were infected with C-PA or WSN at a multiplicity of infection (MOI) of 0.01. Viruses were harvested 8, 16, 24, 36, 48, and 60 hr (additional 72 and 90 hr for Vero cells) after infection and their titers on MDCK cells measured by a plaque-formation assay. The mean and standard deviation (error bar in the graph) of each plaque titer were calculated from 3 independent experiments. Statistical significance was evaluated with Student’s t-test. **p < 0.01, ***p < 0.005.
