Attenuation of H7N9/AAca in ferrets.

Groups of three ferrets were intranasally inoculated with 106 EID50 of H7N9/AAca or rAH/1. The animals were killed on day 4 p.i. and their nasal turbinates, tonsils, tracheas, lungs and brains were collected for virus titration in eggs. The dashed line indicates the limit of detection. a, P < 0.05 and b, P < 0.01 compared with the corresponding value for rAH/1-inoculated animals.
