| Reservoir competence for the Newcastle Disease virus (NDV) was evaluated in sparrows (Passer domesticus, Linnaeus 1758) captured on a commercial poultry farm and a chicken hatchery in the State of Pernambuco, Northeastern Brazil. A total number of 103 birds collected from a poultry farm (24/103) and a chicken hatchery (79/103) were examined. Hemagglutination inhibition tests, isolation, and viral characterization were performed in all samples collected from each bird. Titers ranging from 1:2 to 1:64 were detectable in 10.68% of sparrows, but positive serology and viral isolation were obtained only from sparrows captured at the hatchery. Hemagglutination activity was inhibited by anti-avian paramyxovirus serotype 1 (APMV-1) serum, and this sample showed an... |
