Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Metacestode (larval tapeworm) predilection sites in intermediate ruminant and porcine hosts.
Step 2: Detailed Explanation:
Metacestode larval forms and intermediate host tissue predilection:
1. {Taenia hydatigena (Definitive host: Dog): Its larval stage, {Cysticercus tenuicollis (thin-necked bladderworm), migrates through the sheep liver parenchymal tracks and attaches as large fluid-filled cysts to the peritoneal cavity, mesentery, and omentum of sheep and goats.
2. Taenia saginata: Cysticercus bovis in bovine skeletal muscle.
3. Taenia solium: Cysticercus cellulosae in porcine muscle.
4. Echinococcus multilocularis: Alveolar multilocular hydatid cysts in rodent liver.
Step 3: Final Answer:
Therefore, the parasite larval stage found in sheep peritoneal cavity is Taenia hydatigena, corresponding to option (B).
