Title: ROLE OF FREE LIVING BIRDS AS RESERVOIRS OF NEWCASTLE DISEASE VIRUS INFECTION

This study was aimed to assess the epidemiological role of free living birds in the transmission of ND. A total of 63 cloacal swabs/droppings from various categories of free living birds (desi chicken, pigeon, turkeys, crows, sparrows, geese, parrots) were collected and inoculated into specific pathogen free embryonated chicken eggs for isolation of Newcastle disease virus (NDV). Four NDV isolates were obtained out of 63 cloacal swabs inoculated and the isolates were characterized as velogenic and lentogenic pathotypes based on mean death time (MDT) and intracerebral pathogenicity index (ICPI). It is concluded that free living birds may play an important role in the transmission of NDV to domestic chicken and enforce the biosecurity measures to minimize the effective contact between them.Read More
