| Abstract |
|
Newcastle disease (ND) is one of the major viral diseases of
poultry causing great economic losses to the poultry industry. This
study was aimed to assess the role of pigeons in the epidemiology of ND.
A total of 70 cloacal swabs/droppings from pigeons were collected and
inoculated into specific pathogen free embryonated chicken eggs for
isolation of Newcastle disease virus
(NDV). Only one NDV isolate was obtained out of 70 cloacal swabs
inoculated and the isolate was characterized as velogenic pathotype
based on mean death time (MDT) and intracerebral pathogenicity index
(ICPI). It was concluded that pigeons may play an important role in the
transmission of NDV to domestic chicken. Hence biosecurity measures have
to be strictly followed for avoiding the contact between free living
pigeons and domestic chicken for effective prevention of ND.
