Question

Match List-I with List-II: 

List-I (Name of the virus)	List-II (Disease)
(A) Atadenovirus	(I) Malignant catarrhal fever in cattle
(B) Macavirus	(II) Peste des petits ruminants
(C) Parapoxvirus	(III) Egg drop syndrome-76
(D) Morbillivirus	(IV) Contagious ecthyma in goats

Choose the correct answer from the options given below:

• (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Using a single well-known connection, such as matching the genus Morbillivirus (D) to Peste des petits ruminants (PPR) (II), helps you identify the correct option immediately.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This matching question is centered on veterinary virology, testing our knowledge of viral taxonomy (genera) and the corresponding diseases they cause in domestic animals and poultry.

Step 2: Detailed Explanation:
Let us analyze each virus genus from List-I and match it with the correct disease in List-II:
- (A) Atadenovirus:
This genus belongs to the family Adenoviridae.
Egg drop syndrome virus 1 (EDSV-76), which causes sudden drops in egg production and poor eggshell quality in laying hens, is classified within the genus Atadenovirus.
Therefore, (A) matches with (III) Egg drop syndrome-76.
- (B) Macavirus:
This genus belongs to the subfamily Gammaherpesvirinae of the family Herpesviridae.
Alcelaphine gammaherpesvirus 1 and Ovine gammaherpesvirus 2 (which are members of the genus Macavirus) are the causative agents of Malignant Catarrhal Fever (MCF) in cattle.
Therefore, (B) matches with (I) Malignant catarrhal fever in cattle.
- (C) Parapoxvirus:
This genus belongs to the subfamily Chordopoxvirinae of the family Poxviridae.
Orf virus, a member of the genus Parapoxvirus, causes a highly contagious pustular dermatitis commonly referred to as Contagious Ecthyma (sore mouth) in sheep and goats.
Therefore, (C) matches with (IV) Contagious ecthyma in goats.
- (D) Morbillivirus:
This genus belongs to the family Paramyxoviridae.
Peste des petits ruminants virus (PPRV), which causes an acute, highly contagious respiratory and digestive disease in small ruminants, belongs to the genus Morbillivirus.
Therefore, (D) matches with (II) Peste des petits in ruminants.
Combining these individual matches, we obtain the sequence: (A) - (III), (B) - (I), (C) - (IV), (D) - (II).

Step 3: Final Answer:
The correct matching sequence corresponds to Option (B).
