Percentage survival and clinical score of IBV infected chickens.

(A) Survival rate of 1-day-old chicks after intranasal infection with IBV 3575/08, 2575 WT, 2575 AT. Chickens receiving PBS were served as control. (n = 6 per group) (B) Following intranasal infections in 2-week-old chickens, the daily averages of observed clinical scores within 6 days were recorded. Data was presented as means ± s.e.m. (n = 5 per group) (C) Mean clinical scores of each group during the observation period are indicated (n = 5 per group). See Methods for detailed clinical score interpretation. ns: non-significant. **P < 0.01. ***P < 0.001.
