Abstract
Newcastle disease (ND) is one of the most
important diseases of avian species across the world. The present study was
conducted to investigate the carrier potential of four common wild birds towards
ND virus. Indian mynah (n=25), house sparrow (n=25), house crow (n=25) and
pigeons (n=25) were captured using mist netting technique from the vicinities of
different poultry farms. Cloacal swabs were taken and processed for RT-PCR. The
carrier potential of pigeons, sparrows, crows and mynah for NDV was found to be
24, 20, 16 and 16%, respectively. These results highlighted that these common
wild birds are the major cause of spread of ND viruses and there is need to
consider them all as a high risk species for transmitting ND viruses between
premises.
