Molecular Characterization and Phylogenetic Study of Newcastle Disease Viruses Isolated in Iran, 2014–2015

Molecular characterization of haemagglutinin-neuraminidase gene among virulent Newcastle disease viruses isolated in Iran

Background: Virulent Newcastle disease virus (vNDV) causes great economic losses to the poultry industry throughout the world. Despite the endemicity of Newcastle disease (ND) and occurrence of recurrent outbreaks, the nature and genetic features of circulating NDV strains in Iran are largely unknown. Aims: This study was conducted to characterize 13 NDV isolat...

Phylogenetic characterization of the fusion genes of the Newcastle disease viruses isolated in Fars province poultry farms during 2009-2011

Despite routine vaccination programs against Newcastle disease (ND), sporadic cases have occasionally occurred that remain a constant threat to commercial poultry. Ten isolates of Newcastle disease viruses (NDV) from infected broiler chicken cases were obtained from various locations in Fars province during 2009-2011 and genetically analyzed using reverse transcription polymerase chain reaction...

Biological and Molecular Characterization of Newcastle Disease Virus Isolated from Iran

Perspective on Possible Recombination Event in Fusion Protein Gene of Newcastle Disease Viruses Isolated in Iran

Background and Aims: Newcastle disease (ND), caused by the virulent Newcastle disease virus (NDV), is one of the most important viral diseases in birds. In recent years recombination occurring throughout the NDVs genome isolated in China and Indonesia has been reported. This study was focused to investigate the recombination events in the F gene of the Iranian NDVs to generate useful data that ...

Phylogenetic characterization of Newcastle disease viruses isolated in Taiwan during 2003-2006.

Isolates of Newcastle disease virus (NDV) from chicken cases were obtained from various locations in Taiwan during 2003-2006 and were genotypically analyzed by using reverse transcription polymerase chain reaction (RT-PCR) with primers specific to the viral fusion (F) protein gene (534 bp). Part of the amplified F protein DNA product (nucleotide sequence 47-418) and the deduced amino acid seque...

Phylogenetic study based on the phosphoprotein gene of Iranian Newcastle disease viruses (NDV) isolates, 2010 -2012

BACKGROUND: Newcastle disease virus (NDV) is the causativeagent of the Newcastle disease (ND), a highly contagiousdisease in birds that causes significant economic losses to thepoultry industry worldwide. ND is endemic in Iran and outbreaksare reported regularly in commercial poultry flocks and differentspecies of birds. OBJECTIVES:The current study was carried outto characterize NDV based on p...
