Step 1: Understanding the Concept:
Veterinary obstetrics, pathology, and theriogenology utilize precise terminology to describe fetal presentations, birth anomalies, developmental defects, and infectious diseases.
Step 2: Detailed Explanation:
Let us match the terms in List-I with their corresponding definitions or synonyms in List-II:
- (A) Breech Presentation \(\rightarrow\) (III) Bilateral hip flexion:
In veterinary obstetrics, a breech presentation is a posterior longitudinal presentation where the fetus's hind legs are flexed forward at the hip joints.
This results in the buttocks presenting first at the maternal pelvic inlet, which often causes dystocia.
- (B) Monster \(\rightarrow\) (IV) Amorphous Globosus:
An Amorphous Globosus (also known as an acardiac monster) is an asymmetrical, skin-covered spherical tissue mass.
It lacks recognizable external limbs or internal organs and is attached to the placenta of a normal twin fetus, classifying it as a classic fetal monster.
- (C) Still Birth \(\rightarrow\) (I) Birth of dead fetus:
A stillbirth is defined as the delivery of a dead fetus after the stage of viability has been reached.
- (D) Bang's Disease \(\rightarrow\) (II) Brucellosis:
Bang's disease is the historic and common clinical name for bovine brucellosis, caused by Brucella abortus.
It was named after Bernard Bang, the Danish veterinarian who first isolated the pathogen.
This matches the sequence: (A)-(III), (B)-(IV), (C)-(I), (D)-(II), which corresponds to Option (D).
Step 3: Final Answer:
The correct matching is represented by Option (D).
