Point mutation revealed the resurgence of sub-genotype VII.2 Newcastle disease virus in Israel.

RESEARCH HIGHLIGHTSIn 2019, there was a resurgence of NDV from sub-genotype VII.2 in Israel, in an already endemic area of sub-genotype VII.1.A mismatch at the 3' end of the reverse primer caused a diagnostic failure of the NDV virulence differentiation rRT-PCR assay.The 2019 NDV sub-genotype VII.2 virus is genetically close to viruses from Jordan (2018) and Pakistan (2015-2016).
