ABSTRACTNewcastle disease (ND), caused by the virulent Newcastle disease virus (NDV), is one of the most important viral diseases of birds globally, but little is currently known regarding enzootic trends of NDV in northeastern China, especially for class I viruses. Thus, we performed a surveillance study for NDV in northeastern China from 2013 to 2015. A total 755 samples from wild and domestic birds in wetlands and live bird markets (LBMs) were collected, and 10 isolates of NDV were identified. Genetic and phylogenetic analyses showed that five isolates from LBMs belong to class I subgenotype 1b, two (one from wild birds and one from LBMs) belong to the vaccine-like class II genotype II, and three (all from wild birds) belong to class II subgenotype Ib. Interestingly, the five class I isolates had epidemiological connections with viruses from southern, eastern, and southeastern China. Our findings, together with recent prevalence trends of class I and virulent class II NDV in China, suggest possible virus transmission between wild and domestic birds and the potential for an NDV epidemic in the future.

Virulent strains of Newcastle disease virus (NDV) cause Newcastle disease (ND), a devastating disease of poultry and wild birds. Phylogenetic analyses clearly distinguish historical isolates (obtained prior to 1960) from currently circulating viruses of class II genotypes V, VI, VII, and XII through XVIII. Here, partial and complete genomic sequences of recent virulent isolates of genotypes II and IX from China, Egypt, and India were found to be nearly identical to those of historical viruses isolated in the 1940s. Phylogenetic analysis, nucleotide distances, and rates of change demonstrate that these recent isolates have not evolved significantly from the most closely related ancestors from the 1940s. The low rates of change for these virulent viruses (7.05 × 10−5and 2.05 × 10−5per year, respectively) and the minimal genetic distances existing between these and historical viruses (0.3 to 1.2%) of the same genotypes indicate an unnatural origin. As with any other RNA virus, Newcastle disease virus is expected to evolve naturally; thus, these findings suggest that some recent field isolates should be excluded from evolutionary studies. Furthermore, phylogenetic analyses show that these recent virulent isolates are more closely related to virulent strains isolated during the 1940s, which have been and continue to be used in laboratory and experimental challenge studies. Since the preservation of viable viruses in the environment for over 6 decades is highly unlikely, it is possible that the source of some of the recent virulent viruses isolated from poultry and wild birds might be laboratory viruses.

The first complete genome sequence of a strain of Newcastle disease virus (NDV) of genotype XVII is described here. A velogenic strain (duck/Nigeria/903/KUDU-113/1992) was isolated from an apparently healthy free-roaming domestic duck sampled in Kuru, Nigeria, in 1992. Phylogenetic analysis of the fusion protein gene and complete genome classified the isolate as a member of NDV class II, genotype XVII.

Newcastle disease is an OIE-listed and highly contagious viral avian disease inflicting great economic losses and constituting a serious threat to poultry farms all over the world. The paper provides monitoring research results for Newcastle disease among poultry and wild birds in the Russian Federation for 2017. The tests were carried out with diagnostic kits for Newcastle disease virus antibody detection by immunosorbent assay and HI at the FGBI “ARRIAH” Reference Laboratory for Viral Avian Diseases (Vladimir). Biological material delivered from Rosselkhoznadzor Territorial Administrations was collected from 31 678 domestic and 433 wild and synanthropic birds from 22 and 4 regions of the Russian Federation, respectively. The paper shows different levels of seroprevalence in poultry from industrial poultry establishments of a closed type and backyards and in wild birds of various regions of the Russian Federation. Almost total Newcastle disease seroprevalence was found in adult poultry from industrial closed establishments due to a total vaccination against the disease. Broilers demonstrated a relatively low average Newcastle disease virus seroprevalence because of an insufficient antibody level by the moment of blood sampling (mostly during slaughter). On average, antibodies to Newcastle disease virus were detected in one third of samples from backyard poultry. With that, high seroprevalence was registered on farms of North Caucasian Republics and southern regions of the Russian Federation. Seroprevalence in wild birds was moderate. Thus, the monitoring research indicates an unstable epidemiological situation for Newcastle disease in the Russian Federation and the remaining risk of disease outbreak on industrial and backyard farms.
