In 2010 and 2011, several devastating Newcastle disease (ND) outbreaks occurred in China, affecting broilers, layers, and breeders. The CK-JSX1-201005 virus was isolated from broiler breeder flocks vaccinated with the classical ND virus (NDV) vaccine program, but laying rate decreased from 80% to 30 to 40% in the clinic. Here, we report the complete genome sequence and molecular characteristic ...

Background: Newcastle disease is a major avian disease that causes enormous economic loss in poultry industry. There have been a number of reports on the suitability of plant-based recombinant vaccine against this disease. Fusion (F) and hemagglutinin-neuraminidase (HN) epitopes of the Newcastle disease virus (NDV) represent the major immunogenic sites for development of recomb...

Newcastle disease (ND) is a contagious and widespread avian disease affecting most species of birds. ND virus (NDV) is the only member of the avian paramyxovirus serotype 1 (APMV1) causing ND outbreak in bird flocks. The technique of nucleic acid sequence-based amplification (NASBA) is a potential method to rapidly and reliably detect NDV isolates. Here, we describe an effective and unprecedent...

Newcastle disease virus (NDV) is an avian virus that is being evaluated as a vaccine vector for the delivery of foreign genes in mammals. The use of NDV as a vaccine vector in these species offers two major advantages. First, NDV is highly attenuated in mammals, rendering its use inherently safe. Second, mammals lack pre-existing NDV immunity, which minimizes the risk of vaccination failure. ND...

Two complete genome sequences of Newcastle disease virus (NDV) are described here. Virulent isolates pigeon/Pakistan/Lahore/21A/2015 and pigeon/Pakistan/Lahore/25A/2015 were obtained from racing pigeons sampled in the Pakistani province of Punjab during 2015. Phylogenetic analysis of the fusion protein genes and complete genomes classified the isolates as members of NDV class II, genotype VI.

Velogenic Newcastle disease virus (NDV) was recovered from two dead Eurasian Scops Owls (Otus scops) from a wildlife rescue center in Korea during 2005. Phylogenetic analysis based on the sequence of the partial fusion (F) protein revealed that the isolates had the highest level of homology to recent Korean NDV strains from poultry.

In 2000, three Newcastle disease virus (NDV) strains were isolated from outbreaks of infection in layers, ducklings, and geese in the same region of China during the same time period. Here, we report their complete genome sequences, which belong to the NDV genotype VIId. This discovery might provide clues as to the evolution of the NDVs of different avian origins.

Goose/GD/2010 is a newly emerging Newcastle disease virus (NDV) isolated from a sick goose flock in southern China. Here, we report the complete genome sequence of this isolate, which belongs to NDV subgenotype VIIb. This is the first report about the complete genome information of an isolate of subgenotype VIIb in China.

To our knowledge, our study is the first to report the whole-genome sequence of an ostrich-origin Newcastle disease virus (NDV) isolate, abbreviated as Ostrich/SX-01/06. Phylogenetic analysis revealed that this isolate belongs to the subgenotype c in class II. The identification of the complete genome will provide useful information regarding ostrich diseases, especially NDV.
