Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

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

Hint:

Diagnostic Culture Media:
Bismuth Sulfite Agar = Salmonella spp.
Baird-Parker = Staphylococcus aureus
MYP Agar = Bacillus cereus
Oxford Moxalactam = Listeria monocytogenes.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Selective differential bacteriological culture media and target foodborne pathogens.

Step 2: Detailed Explanation:
Matching selective diagnostic media in List I with target bacterial pathogens in List II:
- A. Bismuth Sulfite Agar (BSA): Highly selective diagnostic medium for II. Salmonella spp. (colonies appear jet black with surrounding metallic silvery sheen due to $\text{H}_2\text{S}$ and bismuth reduction).
- B. Baird-Parker Medium: Selective diagnostic agar for III. {Staphylococcus aureus (black colonies surrounded by clear egg-yolk lecithinase-clearing zones).
- C. Mannitol Egg Yolk Polymyxin (MYP) Agar (Mossel): Selective agar for enumerating IV. {Bacillus cereus (pink-red mannitol-negative colonies with dense egg-yolk lecithinase precipitation halo).
- D. Moxalactam Agar (Oxford PALCAM Medium): Selective diagnostic medium for I. {Listeria monocytogenes (black esculin-hydrolyzing colonies with halos).
Matching sequence: A-II, B-III, C-IV, D-I.

Step 3: Final Answer:
Hence, the correct matching is A-II, B-III, C-IV, D-I, matching option (C).
