Day 2 | Day 3 | Day 6 | Day 9 | |
H7N3 | 3.9 (0.6) | 5.4 (0.7) | 6.0 (0.8) | 5.9 (0.5) |

H7N3 PAP190S | 4.5 (1.0)* | 4.9 (1.1) | 5.6 (0.7) | ND |
Average lung virus titers in H7N3 or mutant virus infected DBA/2J animals. Results are the average and standard deviation of the log10-transformed virus titer obtained from at least two different experiments.
