Isolation and characterization of genotype XIII Newcastle disease virus from Emu in India.

ABSTRACT: Newcastle disease virus (NDV) infects at least 241 species of pet and free-living birds in addition to domesticated avian species. Wild, feral and domesticated birds are recognized reservoirs of NDV, and contribute to the epidemiology of NDV in the domesticated poultry. The biological and molecular characterization of velogenic NDV (vNDV) from emus is limited. In this study, 54 tissues were collected from eight Emu flocks between May 2010 and January 2012 from highly poultry-dense areas of India including Namakkal, Hyderabad and Bareilly regions. The presence of vNDV was confirmed by virus isolation, fusion (F)-gene based RT-PCR, sequencing of the cleavage site and the virulence scored. One out of eight flocks received from Hyderabad region was found positive for NDV and the in vivo pathot
