Detection of residual IBDV in the BFs after challenging. The residual IBDV was detected in the BFs of all chickens by real-time PCR. The positive plasmid VP5-T was diluted as log10 dilutions and measured as the standard curve. Data were analyzed and expressed as mean ± SD, ^ ^P < 0.01 vs challenge-treated chickens and expressed as mean ± SD, ^∗∗P < 0.01 vs rClone30-treated chickens.
