Question

Match List-I with List-II: 

List I (Infectious diseases)	List II (Diagnostic techniques)
(A) Brucellosis	(I) Standard tube agglutination test
(B) Paratuberculosis	(II) Agar gel immunodiffusion assay
(C) Tuberculosis	(III) CAMP test
(D) Streptococcus agalactiae in milk	(IV) Stormont test

Choose the correct answer from the options given below:

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

Hint:

The CAMP test is a classic diagnostic tool for identifying Streptococcus agalactiae in milk (D-III). Using this specific microbiological association helps narrow down the correct option immediately.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
This matching question tests the knowledge of specific diagnostic tests used to identify bacterial and mycobacterial infections in livestock.

Step 2: Detailed Explanation:
Let us analyze each infectious disease and its corresponding diagnostic technique:
- Brucellosis (A): The Standard Tube Agglutination Test (STAT) is a classic serological method used to detect and quantify antibodies against Brucella abortus in blood serum. This matches with (I).
- Paratuberculosis Johne's Disease (B): The Agar Gel Immunodiffusion (AGID) assay is a common, specific serological test used to detect antibodies against Mycobacterium avium subsp. paratuberculosis in sheep and goats. This matches with (II).
- Tuberculosis (C): The Stormont test is a specialized, highly sensitive double-injection intradermal tuberculin test developed to detect tuberculosis in cattle. This matches with (IV).
- Streptococcus agalactiae in milk (D): The CAMP test (Christie-Atkins-Munch-Petersen test) is used to identify S. agalactiae based on its ability to produce a synergistic zone of hemolysis when grown alongside Staphylococcus aureus. This matches with (III).
Combining these individual linkages, the matching sequence is (A) - (I), (B) - (II), (C) - (IV), (D) - (III).

Step 3: Final Answer:
The matching sequence is represented by option (C).
