Complete genome sequence of a novel isolate of avian orthoavulavirus serotype 1 from Himalayan Griffon vulture

Abstract Newcastle disease virus (NDV), also known as orthoavulavirus 1, is an avian pathogen that was originally identified in 1926 [10, 16]. NDV infection has been reported in a wide range of birds with varied degrees of susceptibility [14]. Several countries worldwide, including Korea, India, Sri Lanka, Japan, Australia, and the Philippines, reported successive ND outbreaks [1, 6, 23, 27]. According to National Animal Disease Referral Expert System (NADRES) data, NDV outbreaks have been reported recently from different states in India including Andaman and Nicobar Islands, Pondicherry, West Bengal, Tripura, Manipur, Meghalaya, Haryana, Nagaland, Assam, Arunachal Pradesh. Many isolates have been reported from wild avian species apart from poultry in India [11, 12, 22]. On the basis of virulence, NDV strains are broadly categorized as lentogenic (least), mesogenic (moderately), and velogenic (highly) pathotypes [2].
