Genetic Compatibility and Virulence of Reassortants Derived from Contemporary Avian H5N1 and Human H3N2 Influenza A Viruses

Figure 2

Characteristics of moderate to low yield avian-human reassortant viruses in cell culture.

Symbols and virus nomenclatures are the same as described in Figure 1. Rescue efficiency represents virus titer (log10 pfu/ml) from cell cultures at 72 hours after transfection; geometric mean from 3 independent experiments. Plaque formation by reassortant viruses with <100 pfu/ml rescue efficiency was not determined (ND).
