Fig. 1From: Transcription profiles of the responses of chicken bursae of Fabricius to IBDV in different timing phasesQuantification of the infectious bursal disease virus (IBDV) VP2 gene levels in the bursae of Fabricius in the mock group and the infection group by real-time PCR. The data were expressed as the average ratio of IBDV/β-actin. **Indicates P < 0.01 when samples taken from day 1 postinfection in the infection group were compared with those from day 3 in the infection groupBack to article page
