Serum antibodies against Newcastle disease and Avian Influenza in birds of pley in Chile

Journal Title: Revista MVZ Cordoba - Year 2012, Vol 17, Issue 3

Abstract

Objective. To detect the presence of blood serum antibodies against Newcastle disease (ND) and Avian influenza (AI) viruses, to understand the contribution of wild birds in transmission of these viruses in Chile. Materials and methods. Sixty-three birds belonging to orders Falconiformes and Strigiformes were analyzed from bird rehabilitation centers in central and south-central Chile. Hemagglutination inhibition (HIA) was used to detect antibodies against the ND virus and further AI virus typing was done by agar gel immune-diffusion (AGID) and ELISA. Results. 14 birds we found (22.2%) with serum antibodies against ND virus; however, there were no blood serum antibodies to AI virus. Conclusions. Birds of prey from rescue centers have been detected positive for serum antibodies against ND virus. Birds of prey could have become positive via direct consumption of chickens vaccinated against ND or from chickens indirectly exposed to the vaccine through different administrative procedures (aerosols, water troughs) or after the admission of migratory birds to rescue centers, which could facilitate the spread of ND from their countries of origin, and should be investigated.
