In terms of production, poultry farming is one of the world’s most important livestock because it produces low-cost animal protein and eggs. Due to various disease outbreaks associated with extensive economic losses, the industry is constantly threatened. Newcastle disease (ND) may be one of the most important diseases to monitor in poultry in Sweden since the country is classified as a Newcastle – free and vaccine–free country within the EU (82/894/EEG). ND is caused by high virulent variants of avian paramyxovirus of serotype 1 (APMV-1). The study's main goal was to investigate the prevalence of APMV1 among wild birds in Sweden as a part of the surveillance for the disease. A total of n= 484 wild bird samples collected either at Ottenby Bird Observatory, Öland, or received to the National Veterinary Institute, SVA, with suspicion of influenza A viruses (AIV) were used in this study. Four pigeon samples were found positive for a high virulent type of APMV-1 belonging to class II, genotype VI and a low virulent type of APMV-1 belonging to class II, genotype I, was found in one sample from a pheasant. The results of this study are a good indication that pigeons and pheasants may constitute a reservoir for low and high virulent strains of APMV-1. Therefore more focused studies and continued surveillance of APMV-1 in wild birds are critical for improving disease control strategies.
