Table 1. The reassortant influenza H7N9 ca virus is ca and ts in CEF cells.
Virus | Mean titer±SE (log10 CCID50/ml) | ca a phenotype | ts b phenotype | ||
---|---|---|---|---|---|
25°C | 33°C | 39°C | |||
Ah01/H7N9 | 2.8±0.01 | 7.0±0.08 | 6.8±0.03 | - | - |
Ah01/AA ca | 5.9±0.02 | 6.8±0.06 | 2.5±0.01 | + | + |
a ca = difference between the mean CCID50 at 33°C and 25°C ≥100-fold.
b ts = difference between the mean CCID50 at 33°C and 39°C ≥100-fold.
