  • a Adult mallard ducks were inoculated with 1 ml of virus by the intranasal, intraocular, intratracheal, and intracloacal routes (a total of 105 PFU). Three animals were euthanized on day 3 or 6 p.i. for virus titration. When virus was not recovered from all three animals, individual titers were recorded.

  • b One-week-old mallard ducks were infected intranasally and orally with 300 μl of HK213Egg virus (a total of 105 PFU). Three ducks from each infected group were sacrificed on day 3, 6, or 12 p.i. for virus titration. When virus was not recovered from all three ducks, individual titers were recorded.

  • c —, virus was not isolated.

  • d S.I., small intestine.

  • e L.I., large intestine.
