NiV is a member of the genus Henipavirus in the subfamily Paramyxovirinae, family Paramyxoviridae. It has several distinctive genetic and biologic features [14, 15, 16, 17, 18] although its morphology and genome organization is similar to that of other members of the subfamily. NiV has six genes arranged in tandem, 39-N, P, M, F, G and L-59 [15, 16] . The N, P and L are required for reconstituting viral RNA polymerase activity, the matrix protein M is required for particle formation and budding, and the two surface glycoproteins G and F are required for attachment and entry into the host cell [19, 20] . EphrinB2 and B3 have been identified as the NiV entry receptors [21, 22, 23] . After fusion of the virus and the cell membrane, the viral ribonucleoprotein is released in to the cell cytoplasm. Following transcription and replication, the viral components migrate to the plasma membrane for assembly and budding of progeny particles [24, 25] .
