  1. Two groups of SPF broilers (B1–2) and two groups of SPF layers (L1–2) were inoculated orally at day-old with either a FAdV-D or -E strain, whereas one group SPF broilers (B0) and one group of SPF layers (L0) were kept uninfected. Birds were routinely euthanized and sampled at 4, 7, 10, 14 and 21 dpi. In groups B1 and B2, five birds with severe clinical signs were sampled between 5 and 7 dpi.
  2. aBirds found dead or had to be euthanized due to poor condition.
  3. bNot applicable.
  4. cControl group.
