Question

Match List I with List II 

 

• A. A-III, B-IV, C-I, D-II
• B. A-II, B-IV, C-I, D-III
• C. A-IV, B-II, C-I, D-III
• D. A-IV, B-III, C-II, D-I

Hint:

The "Wheelbarrow test" is an extremely unique clinical sign-based field test specific to Jaagsiekte (Ovine Pulmonary Adenomatosis) in sheep.
Pairing B-III with the well-known Coggin's test for Equine Infectious Anemia (A-IV) makes finding the correct sequence (D) simple.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Veterinary diagnostic procedures utilize specific immunodiagnostic assays, clinical maneuvers, or tumor-associated cellular markers to identify viral infections or neoplastic diseases in domestic animals.

Step 2: Detailed Explanation:
Let us analyze each diagnostic test, antigen, or clinical test:
- A. Coggin's test: This is the gold-standard agar gel immunodiffusion (AGID) test used globally to detect antibodies against Equine Infectious Anemia (EIA) virus in horses.
Thus, A matches with IV.
- B. Wheelbarrow test: This is a classical clinical field maneuver for Jaagsiekte (Ovine Pulmonary Adenomatosis).
Lifting the hind legs of a suspected sheep like a wheelbarrow causes copious amount of clear surfactant-rich fluid to drain from the nostrils due to neoplastic secretory activity in the lungs.
Thus, B matches with III.
- C. MATSA (Marek's Disease Tumor-Associated Surface Antigen): This is a specific surface glycoprotein antigen expressed on cells transformed by Marek's Disease Virus, distinguishing Marek's Disease (MD) from other lymphoid tumors in chickens.
Thus, C matches with II.
- D. COFAL test (Complement Fixation for Avian Leukosis): This is a diagnostic group-specific assay used to detect viral antigen or antibody associated with the group-specific antigen of Avian Leukosis viruses.
Thus, D matches with I.

Step 3: Final Answer:
Matching these parameters gives: A-IV, B-III, C-II, D-I, which corresponds to option (D).
