Résumé : 21 A/PMV-1 viruses were isolated from pigeons and characterized using polyclonal and monoclonal antisera in hemagglutination inhibition, sero-neutralization and immunoprecipitation studies. Polyclonal and monoclonal antibodies directed against the HN and F proteins of Italien virus reacted with all pigeon isolates showing a close relationship between chicken velogenic and pigeon viruses. Differences in the M.W. of F0, P and M proteins were however observed between pigeon and chicken Italien virus. Marked differences in virulence were recorded among pigeon isolates; these were reflected by great variation in the IVPI of the different strains. © 1986 Springer-Verlag.
