Abstract	The northwest of Iran shares long borders with three neighboring countries; therefore, it is considered one of the main entry portals of Newcastle disease virus (NDV) into the country. Ten virulent NDVs were recovered from 19 poultry farms of various prefectures in northwestern Iran during Newcastle disease outbreaks in 2010. The isolates were genotypically analyzed using an F-gene-specific reverse transcription polymerase chain reaction (RT-PCR) assay. The amplified F gene (nucleotides 189-1666) sequences of the NDV isolates were compared phylogenetically with those of previously published strains in GenBank. All of the NDV isolates belonged to genotype VIIb and were closely related to some isolates from Iran, Russia, and Sweden. Therefore, it can be postulated that these isolates evolved from previously reported strains. The velogenic viruses carried the motif 112R-R-Q-K-R/F117 at the F0 cleavage site and a unique substitution of 190L→F which had never been reported in any NDV genotype VIIb isolate. They shared high sequence similarity with each other but were distinct from current NDV vaccines and NDV strains reported from other countries. This information is fundamental for improving the efficacy of controlling strategies and vaccine development for NDV.
