Abstract
- Following recent Newcastle disease virus (NDV) outbreaks in Iranian poultry farms which were mostly associated with lesions of the avian gastrointestinal tract, it was speculated that the scale of the outbreaks could be attributed in part to co-circulating infectious agents or a new NDV genotype/subgenotype. This speculation was due to the isolation of a few 5th panzootic subgenotype VII.2 viruses from Iranian poultry farms in 2017. Samples from different species of commercial and domestic birds were collected from different provinces of Iran, 19 of which were selected for the current study. Phylogenetic analyses showed that the recent outbreaks have been caused by only one agent, i.e. the distinctive NDV subgenotype VII.1.1 (previously known VIIl) viruses that seem to be circulating predominantly in Iran, but have also been sporadically reported from Iraq among neighbouring countries. At most, 96.3–96.7% BLAST identity to non-Iranian VII.1.1 isolates was observed. Genetic distance values of
