In 1981, in the Mediterranean region of Europe, a contagious disease resembling to Newcastle disease (ND) of poultry appeared among racing and other breeding pigeons. The causative agent was an antigenic variant of ND virus (NDV) of chickens, and It became known as pigeon paramyxovirus-1 (pPMV-1). Genetic analysis of 32 pPMV-1 strains isolated between 1983 and 2002 in Hungary (Table) was performed using restriction site distribution (Figure 1) and partial sequence evaluation of the fusion (F) protein gene (Figure 2). It has been established that pPMV-1 strains could be placed into a separate genetic lineage (Vlb) of genotype VI NDV strains that also comprised early Middle East and African viruses. Pigeon PMV-1 isolates could be, however, assigned to three epidemiologkally distinct subgroups: early European, North American and recent European. Outbreaks in the '80s were caused by viruses belonging to the first two subgroups, while those in the '90s were dominated by recent European strains both in Hungary and abroad. Genetic composition of isolates has indicated that local disease among pigeons was due to repeated introduction of contemporary strains from abroad, and reflected the distribution of pPMV-1 strains in Europe.
