Question

Raniket disease is caused by _______.

• A. Herpesvirus
• B. Paramyxovirus
• C. Arbovirus
• D. H1N1 influenza virus

Answer 1

The Correct Option is B

Raniket disease is caused by the virus belonging to the Paramyxoviridae family, specifically, the Paramyxovirus genus. It is commonly associated with Newcastle Disease which affects many types of birds, causing respiratory distress and neurologic symptoms. To identify the correct causative agent of Raniket disease, we consider the options provided:

• Herpesvirus
• Paramyxovirus
• Arbovirus
• H1N1 influenza virus

By analyzing these options, we find that:

• Herpesvirus: Known for causing diseases such as chickenpox and cold sores in humans, not related to Raniket disease.
• Paramyxovirus: The correct causative agent of Raniket disease, known to affect birds.
• Arbovirus: Associated with diseases spread by arthropods, not linked to Raniket disease.
• H1N1 influenza virus: A subtype of the influenza virus affecting humans, unrelated to Raniket disease.

Therefore, the correct answer is: Paramyxovirus

Answer 2

The correct answer is (B) Paramyxovirus.

Ranikhet disease (also known as Newcastle disease) is a highly contagious viral disease that affects poultry, caused by the Paramyxovirus of the genus Avulavirus. This virus affects the respiratory, nervous, and digestive systems of birds, leading to high mortality rates in infected flocks.

Let's briefly go over the other options:

(A) Herpesvirus: Herpesviruses cause different types of diseases in animals, but they are not responsible for Ranikhet disease.

(C) Avipoxvirus: Avipoxvirus causes pox diseases in birds, such as fowlpox, but it is not the cause of Ranikhet disease.

(D) H1N1 influenza virus: The H1N1 influenza virus is a strain of the influenza virus that affects humans and some animals, but it is not related to Ranikhet disease in poultry.

Thus, the correct cause of Ranikhet disease is (B) Paramyxovirus.
