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.
