Epizootiology of Newcastle Disease in Waterfowl
Avian Diseases, 1975Antibodies to Newcastle disease virus (NDV) as measured by hemagglutination-inhibition and virus-neutralization tests were detected in 40/236 Canada geese captured while in their southward migration or in their wintering grounds. Antibodies were also found in 37/267 wild ducks and in 20/31 domestic geese.

The virus can be grown to high titre and is easily titrated. Both live attenuated and inactivated vaccines give effective protection under experimental conditions.
