Question

Match List-I with List-II

List-I (Disease)	List-II (Post-mortem lesion)
(A) Theileriosis	(I) Thickening and corrugation of intestinal wall
(B) Johne's disease	(II) Morocco leather like abomasal mucosa
(C) Candidiasis	(III) Punched necrotic abomasal ulcers
(D) Ostertagiosis	(IV) Turkish towel crop

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

Hint:

- "Johne's disease" = corrugated intestine (B-I).
- "Ostertagiosis" = Morocco leather abomasum (D-II).
Recognizing either of these classic lesions immediately narrows down the choices.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This matching question connects classic veterinary infectious and parasitic diseases with their pathognomonic macro-pathological (post-mortem) lesions.
Detailed Explanation:
Let us match the diseases with their classic post-mortem findings:
- (A) Theileriosis: Infections with Theileria annulata in cattle characteristically produce multiple (III) punched necrotic abomasal ulcers (punched-out ulcers) on the mucosal surface of the abomasum.
- (B) Johne's disease: Infection with Mycobacterium avium subsp. paratuberculosis in ruminants causes chronic granulomatous enteritis, leading to a classic (I) thickening and corrugation of the intestinal wall.
- (C) Candidiasis: Yeast infection in birds (crop mycosis) produces a thickened, white, wrinkled pseudomembrane on the crop mucosa resembling a (IV) Turkish towel crop.
- (D) Ostertagiosis: Infection with the abomasal nematode Ostertagia ostertagi in cattle causes abomasal mucosal hyperplasia, giving it a characteristic (II) Morocco leather abomasal mucosa (or cobblestone abomasum).
This yields the matched sequence:
\[ \text{(A) - (III), (B) - (I), (C) - (IV), (D) - (II)} \]

Step 2: Final Answer:
The correct matching sequence corresponds to Option (B).
