Thermostability and Immunogenicity of Genotype II Avian Orthoavulavirus (AOaV-1) Isolates from Duck () and Parrot ().

Newcastle disease (ND) is a highly contagious viral disease of poultry causing significant economic losses worldwide. Vaccination is considered the most reliable approach to curb the economic menace that is ND, but the thermolabile nature of Newcastle disease virus (NDV) vaccination poses a significant threat to its protective efficacy. This study aimed to profile the thermostability of NDV isolates from duck (As/Km/19/44) and parrot (As/WB/19/91) and evaluate their immunogenic potential in chicks.

A study of risk factors associated with Newcastle disease and molecular characterization of genotype XIII Newcastle disease virus in backyard and commercial poultry in Assam, India.

The continuous emergence of Newcastle disease virus (NDV) poses a persistent threat to the poultry industry. Recent increasing outbreaks of NDV in the North East region of India have highlighted the need to closely monitor and analyze the potential risk factors for Newcastle disease (ND) outbreaks. In the present study, an attempt was made to genotype the circulating Newcastle disease virus (NDV) in the backyard and commercial poultry flocks in Assam, India.

Isolation of genotype VII avian orthoavulavirus serotype 1 from barn owl from Northeast India.

Newcastle disease virus (NDV) affects commercial poultry as well as other avian species in the wild and in captivity. Although the diversity of NDV in domestic chickens has been well understood, little light has been shed on NDV outbreaks in other avian species. We provide an annotated sequence of NDV/Owl/Guwahati/01/20, a virulent strain of NDV isolated from barn owls in captivity from Guwahati in Northeast India.
