“…From the 20 isolated viruses, 9 were identified as APMV-1, 4 were APMV-4, 4 were APMV-7, and 3 were APMV-6. Similar data were obtained by other researchers in monitoring studies of waterfowl who identified viruses of serotypes APMV-1, APMV-4, and APMV-6 (22,34,44,45). In our studies, we obtained only 4 APMV-1 isolates from Charadriiformes.…”

bDespite the existence of 10 avian paramyxovirus (APMV) serotypes, very little is known about the distribution, host species, and ecological factors affecting virus transmission. To better understand the relationship among these factors, we conducted APMV wild bird surveillance in regions of Ukraine suspected of being intercontinental (north to south and east to west) flyways. Surveillance for APMV was conducted in 6,735 wild birds representing 86 species and 8 different orders during 2006 to 2011 through different seasons. Twenty viruses were isolated and subsequently identified as APMV-1 (n ‫؍‬ 9), APMV-4 (n ‫؍‬ 4), APMV-6 (n ‫؍‬ 3), and APMV-7 (n ‫؍‬ 4). The highest isolation rate occurred during the autumn migration (0.61%), with viruses isolated from mallards, teals, dunlins, and a wigeon. The rate of isolation was lower during winter (December to March) (0.32%), with viruses isolated from ruddy shelducks, mallards, white-fronted geese, and a starling. During spring migration, nesting, and postnesting (April to August) no APMV strains were isolated out of 1,984 samples tested. Sequencing and phylogenetic analysis of four APMV-1 and two APMV-4 viruses showed that one APMV-1 virus belonging to class 1 was epidemiologically linked to viruses from China, three class II APMV-1 viruses were epidemiologically connected with viruses from Nigeria and Luxembourg, and one APMV-4 virus was related to goose viruses from Egypt. In summary, we have identified the wild bird species most likely to be infected with APMV, and our data support possible intercontinental transmission of APMVs by wild birds.

“…The avian paramyxovirus host range is very large, and the natural reservoirs of paramyxoviruses of different serotypes are wild birds of aquatic, shore, and terrestrial ecosystems (22,23). Most of the countries with developed industrial poultry production monitor APMVs among both poultry and wild birds.…”

“…Lentogenic APMV-1 was also detected in Haliaetus leucocephalus and Bubo virginianus, but not in Accipiter cooperi, Carthartes aura and C. atratus (Jindal et al, 2010). Although most APMV-1 strains endemic in wild birds are lentogenic, deficient biosecurity in poultry facilities may enable challenge with virulent strains (Camenisch et al, 2008). The raptors in this study may not pose risks to commercial poultry regarding APMV-1.…”

Clinically healthy racing pigeons may harbour notifiable pathogens and serve as an unnoticed reservoir. Thus, 3480 healthy racing pigeons from 172 different lofts were monitored over a period of 2 years for the presence of avian influenza virus (AIV) and avian paramyxovirus-1 (APMV-1). Pharyngeal and cloacal swabs as well as blood samples were collected from juvenile and adult pigeons. Pools of five pharyngeal swabs per loft and age group were initially screened by real-time reverse transcriptase-polymerase chain reaction (rRT-PCR). Pharyngeal and cloacal samples from lofts that were positive or suspect in the AIV rRT-PCR or the APMV-1 rRT-PCR were inoculated into embryonated chicken eggs for virus isolation. In addition, sera were examined for antibodies against AIV by enzyme-linked immunosorbent assay. The antibody levels after vaccination against APMV-1 were determined by haemagglutination inhibition assay. Of the investigated lofts, 0.0 to 1.4% were positive by rRT-PCR for APMV-1 and 0.0 to 6.7% for AIV during this 2-year period with a total of four samplings. No sample yielded replicating virus in egg culture. No antibodies against AIV were detected. Haemagglutination inhibition test of vaccinated racing pigeons indicated age-dependent APMV-1 titres. The results suggest that the examined racing pigeons may have had contact with AIV, but virus replication may have been too low to induce detectable circulating antibody levels. Only a low percentage of samples were positive for APMV-1, but two outbreaks were observed in monitored flocks, indicating ongoing circulation of APMV-1 in the racing pigeon population. These observations highlight the relevance of APMV-1 vaccination and indicate the importance of flock immunity.
