Dynamic analysis of viral load. Same weight of heart (a), liver (b), kidney (c), spleen (d), thymus (e) and bursa of Fabricius (f) of the 1-day-old ducklings were collected at 1, 6, 12, 18, 24, 48 and 72 hpi, and were immediately used for RNA extraction and qRT-PCR measurement as previously described. Viral RNA copies were calculated with formula X = 6.7 × 10(40.812-y)/3.285. “X” is a standard of viral copies while “y” is a standard of values derived from one step real-time PCR. Bars represent means and standard of three individual repeats
