Abstract:

Newcastle disease (ND) is a highly contagious viral disease affecting most of the avian species. The mortality of birds varies with the virulence and pathogenicity of virus that infects the birds and also with susceptibility of birds. Though ducks are resistant to ND, there are some studies reported that the susceptibility of some breeds of ducks to NDV. In this present study, two exotic breeds of ducks (White Pekin and Khaki Campbell) were experimentally infected with 105 Egg Infectious Dose50 of velogenic Newcastle Disease Virus (vNDV) by subcutaneous route on 15th day of age to study the pathogenicity of NDV in ducks. The birds were observed for clinical disease and gross pathology. The clinical signs and death were noticed only in Khaki Campbell ducks and not in White Pekin. Clinical signs were primarily neurologic. Tissues were collected from ducks euthanized on 1st, 3rd, 7th and 21st day of post infection or after disease associated death. The histopathology of collected tissues was studied by haematoxylin and eosin staining. The results confirmed that some of the NDV virulent strains caused the disease in ducks, and played a role in the epidemiology of ND.
