Which of the following causative agents is responsible for Ranikhet disease (also known as Newcastle disease) in poultry ?
Paramyxovirus
Ranikhet disease, known internationally as Newcastle disease, is caused by a paramyxovirus — specifically Avian orthoavulavirus 1, still widely called Newcastle disease virus, a single-stranded RNA virus of the family Paramyxoviridae.
It spreads through respiratory droplets and droppings and shows up as gasping, twisting of the neck, paralysis, greenish diarrhoea and a sudden collapse in egg production. Velogenic strains can wipe out an unvaccinated flock within days, which is why the LaSota and F1 vaccines are central to poultry management in India.
The other agents cause different poultry conditions. Avipoxvirus produces fowl pox with scabby lesions on the comb and wattles, herpesvirus causes Marek's disease and infectious laryngotracheitis, and orthomyxovirus is the family to which avian influenza belongs.
Hence, the answer is Paramyxovirus.
