Which genus is associated with the virus that causes VND?

The virus responsible for causing Virulent Newcastle Disease (VND) is categorized under the genus Avulavirus. This classification is crucial because it highlights the specific viral lineage to which this pathogenic strain belongs. Avulavirus encompasses a range of viruses that primarily infect birds, underscoring the importance of this genus in the context of avian health and veterinary virology.

The association with Avulavirus is not just a taxonomical classification; it also informs researchers and health officials about the virus’s behavior, epidemiology, and potential impact on poultry industries. Understanding that VND is linked to this specific genus aids in developing effective prevention and control strategies to mitigate outbreaks among avian populations.

The other options relate to different viral families or genera: Paramyxovirus is a broader category that includes various viruses but does not specifically focus on VND; Poxvirus pertains to a completely different group of viruses that cause pox diseases; and Thermalivirus is not relevant in the context of Newcastle Disease, making them less suitable options for this specific inquiry. The specificity of Avulavirus to Newcastle Disease is what makes it the correct answer in this context.
