Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Foodborne illnesses and infections are categorized based on their causative biological agents, which include viruses, bacteria, protozoa, and parasitic helminths.
Step 2: Detailed Explanation:
Let us classify the etiology of each of the listed diseases:
1. Toxoplasmosis (A): A parasitic disease caused by the protozoan parasite Toxoplasma gondii, commonly transmitted through undercooked meat or contact with cat feces.
2. Trichinellosis (B): A parasitic disease caused by roundworms (nematodes) of the genus Trichinella, typically acquired by consuming raw or undercooked pork.
3. Shigellosis (C): An acute infectious foodborne diarrheal disease caused by bacteria belonging to the genus {Shigella (such as Shigella dysenteriae). It is transmitted through the fecal-oral route, contaminated water, or poorly handled food. Hence, this is a bacterial disease.
4. Cysticercosis (D): A parasitic tissue infection caused by larval cysts of the pork tapeworm Taenia solium.
Thus, Shigellosis is the only bacterial disease among the options.
Step 3: Final Answer:
Therefore, Shigellosis is a bacterial disease.
