Newcastle disease is considered the most contagious poultry disease and may cause severe economic loss in the poultry industry. The present study was undertaken to focus on molecular and phylogenetic analyses of the hemagglutinin-neuraminidase (HN) gene in the Iranian isolates. The nucleotide sequence of the HN (780-903 nt) coding region of 6 Newcastle disease viruses (NDVs), isolated from various outbreaks in Iran, was determined and aligned with previously published sequences of 26 NDV isolates in GenBank; the resulting alignment was then analyzed in terms of genetic variation. The number of nucleotide sequence variations presented by each of the isolates indicated …
