Bursa of fabricius 4.00 ± 0.66 4.50 ± 0.75
Thymus 4.92 ± 0.52 5.33 ± 0.52
Pancreas 2.58 ± 1.01 1.92 ± 0.28

  1. aTwo-week-old geese were inoculated intranasally (i.n.) with 106 EID50 of each virus in a 0.2 ml volume; three ducks in each group were euthanized on 3 DPI, and virus titer was determined in samples of heart, liver, spleen, lung, kidney, brain, trachea, Small intestine, bursa of fabricius, Thymus, Pancreas and cecal tonsils in eggs [17].
  2. bFor statistical analysis, a value of 1.5 was assigned if the virus was not detected from the undiluted sample in three embryonated hen eggs. Virus titers are expressed as means ± standard deviation in log10EID50/g of tissue.
  3. cNo detected.
